how many pictures can a 32gb memory card hold | big w sd cards

Because the host views the SD card as a block storage device, the card does not require MBR partitions or any specific file system. The card can be reformatted to use any file system the operating system supports. For example:

When NOR flash was developed, it was envisioned as a more economical and conveniently rewritable ROM than contemporary EPROM and EEPROM memories. Thus random-access reading circuitry was necessary. However, it was expected that NOR flash ROM would be read much more often than written, so the write circuitry included was fairly slow and could erase only in a block-wise fashion. On the other hand, applications that use flash as a replacement for disk drives do not require word-level write address, which would only add to the complexity and cost unnecessarily.[citation needed]

The GameCube[b] is a home video game console released by Nintendo in Japan and North America in 2001 and Europe and Australia in 2002. The sixth generation console is the successor to the Nintendo 64 and competed with Sony Computer Entertainment’s PlayStation 2 and Microsoft’s Xbox.
Each NOR flash cell is larger than a NAND flash cell – 10 F2 vs 4 F2 – even when using exactly the same semiconductor device fabrication and so each transistor, contact, etc. is exactly the same size – because NOR flash cells require a separate metal contact for each cell.[49]
If your device is able to use a Secure Digital High Capacity (SDHC) and Secure Digital eXtended Capacity (SDXC) card, you’ll be able to store substantially more photos and videos than traditional SD cards. However, these formats are not backward compatible.
A fairer and more recent system is the ‘class rating’. The SD Association created the speed class rating test which focuses on finding the absolute minimum data transfer rate of SD/SDHC/SDXC cards, as opposed to a sustainable rate.
After researching nearly 50 USB-C SD readers, we tested 12 models that met our requirements in December 2016 and three new models in July 2017. We also looked for models with promising user reviews, although the category is so new that many of the ones we tested don’t have any yet. Then we plugged them into a MacBook Pro (13-inch, late 2016, Two Thunderbolt 3 Ports) and a 2016 Dell XPS 13 (we used a 2017 Dell XPS 15 for our most recent tests) and used AJA System Test and CrystalDiskMark to test their speeds with a SanDisk Extreme Pro UHS-II SD card, a SanDisk Extreme Pro UHS-II microSD card, and a SanDisk Extreme Pro CompactFlash Card. The test results presented here are from our tests on a Windows laptop; our Mac tests were identical, except where noted.

Generally, if you want to shoot HD video or if you plan on taking a lot of high-resolution photos in quick succession (or use a digital SLR’s RAW image file format), buy a Class 10 card. If you’re planning to just take snapshots or occasionally show videos, Class 4 or Class 6 will do. Since even smartphones can record HD video these days, Class 2 cards aren’t the best choice. They’re simply too slow to record HD video, so you’re limiting your device’s features. The price difference between Class 4, Class 6, and Class 10 cards can vary, but not vastly. At the time of this writing, on Newegg.com, 32GB SDHC cards made by Kingston Technology were available in Class 4 for $54, Class 6 for $66, and $73 for Class 10. UHS-1 cards are much, much more expensive than the other cards; Kingston was offering a 32 GB UHS-1 SD card for $293, and that was on sale. Unless you’re a professional who needs absolute certainty in speed when dealing with very large images or high-bitrate video, you don’t need UHS-1. In fact, unless you have professional or semi-professional equipment, you probably won’t even be able to use these cards. Always check your device’s documentation for support information before you commit to a memory card.
Hope in the future that Amazon punishes vendors who ship inferior, counterfeit, or products different than described or pictured. Right now, the only way I see to determine if this might be the case is to S L O W L Y read the 1 and 2 Star reviews for a product. Four or maybe even two years ago, you could comfortably make a purchase based on 4-Stars or above. No more – especially on these commodity products where confusion exists regarding product specifications. [On this product alone: SD vs. SDXC vs. SDHC; Suitability of Capacity; Choice of writing speed for application. For in-depth information see SDCard dot ORG] An overall rating is NO LONGER a sufficient criterion for a purchasing decision since many of these commodity type products have their reviews gamed by paid reviewers.
What’s even scarier – the dead device becomes very hot when plugged in! To me, this indicates that the reader was NOT designed for becoming hot, and became damaged from the heat. Furthermore, it means that the power circuitry is faulty – why would a non-working device draw that much power to become painfully hot? Because of these problems, it becomes very dangerous to plug into a computer. Most modern computers come with current protection to prevent anything bad from happening due to faulty devices, but I wouldn’t take that chance.
Since late 2009, newer Apple computers with installed SD card readers have been able to boot in macOS from SD storage devices, when properly formatted to Mac OS Extended file format and the default partition table set to GUID Partition Table.[97] (See Other file systems below).
The last thing you want to happen when you’re ready to capture that priceless moment with your smartphone is run out of memory. Samsung’s got you covered with its microSD memory expansion cards. Simply slide the card into the expansion slot of your Android™ smartphone and add 256 GB of capacity.
The GameCube is the first Nintendo console to use optical discs as its primary storage medium. The discs are similar to the miniDVD format; as a result of their smaller size and the console’s small disc compartment, the system was not designed to play standard DVDs or audio CDs. The console supports online gaming for a small number of games via the broadband or modem adapter and connects to the Game Boy Advance via the link cable, allowing players to access exclusive in-game features using the handheld as a second screen and controller.
When it comes to flash memory cards, there are three aspects you need to consider: physical format, size, and speed. Each of the three variables has its own set of classes, so you can have anything from a 1GB Class 2 microSD card to a 32GB UHS-1 SDXC card. We’ll explore the distinctions below.
On such SD cards, standard utility programs such as Mac OS X’s “Disk Utility” or Windows’ SCANDISK can be used to repair a corrupted filing system and sometimes recover deleted files. Defragmentation tools for FAT file systems may be used on such cards. The resulting consolidation of files may provide a marginal improvement in the time required to read or write the file,[104] but not an improvement comparable to defragmentation of hard drives, where storing a file in multiple fragments requires additional physical, and relatively slow, movement of a drive head. Moreover, defragmentation performs writes to the SD card that count against the card’s rated lifespan. The write endurance of the physical memory is discussed in the article on flash memory; newer technology to increase the storage capacity of a card provides worse write endurance.
Example applications of both types of flash memory include personal computers, PDAs, digital audio players, digital cameras, mobile phones, synthesizers, video games, scientific instrumentation, industrial robotics, and medical electronics. In addition to being non-volatile, flash memory offers fast read access times, although not as fast as static RAM or ROM.[2] Its mechanical shock resistance helps explain its popularity over hard disks in portable devices, as does its high durability, ability to withstand high pressure, temperature and immersion in water, etc.[3]
In most respects, the above types of flash memory cards differ from those used in enterprise storage. EMC is credited with being the first vendor to include SSDs in enterprise storage hardware when it added them to its Symmetrix disk arrays in 2008, spawning the advent of hybrid arrays that combine flash drives with a traditional spinning disk. Initially, enterprise SSDs in hybrid arrays were relegated for caching read data in flash due to their higher cost and lower endurance compared to HDDs.
USB drive: This portable plug-and-play flash storage device is inserted into a computer’s standard USB port. USB drives ushered in the demise of floppy disks and, to some extent, the reduced use of compact discs.
In 1999, SanDisk, Matsushita, and Toshiba agreed to develop and market the Secure Digital (SD) Memory Card.[58] The card was derived from the MultiMediaCard (MMC) and provided digital rights management based on the Secure Digital Music Initiative (SDMI) standard and for the time, a high memory density.
Integrated USB connector – The SanDisk SD Plus product can be plugged directly into a USB port without needing a USB card reader.[55] Other companies introduced comparable products, such as the Duo SD product of OCZ Technology and the 3 Way (microSDHC, SDHC, and USB) product of A-DATA, which was available in 2008 only.
Four-bit SD bus mode: Uses extra pins plus some reassigned pins. This is the same protocol as the one-bit SD bus mode which uses one command and four data lines for faster data transfer. All SD cards support this mode. UHS-I and UHS-II require this bus type.
Secure Digital includes four card families available in three different sizes. The four families are the original Standard-Capacity (SDSC), the High-Capacity (SDHC), the eXtended-Capacity (SDXC), and the SDIO, which combines input/output functions with data storage.[5][6][7] The three form factors are the original size, the mini size, and the micro size. Electrically passive adapters allow a smaller card to fit and function in a device built for a larger card. The SD card’s small footprint is an ideal storage medium for smaller, thinner and more portable electronic devices.

The guaranteed cycle count may apply only to block zero (as is the case with TSOP NAND devices), or to all blocks (as in NOR). This effect is mitigated in some chip firmware or file system drivers by counting the writes and dynamically remapping blocks in order to spread write operations between sectors; this technique is called wear leveling. Another approach is to perform write verification and remapping to spare sectors in case of write failure, a technique called bad block management (BBM). For portable consumer devices, these wearout management techniques typically extend the life of the flash memory beyond the life of the device itself, and some data loss may be acceptable in these applications. For high reliability data storage, however, it is not advisable to use flash memory that would have to go through a large number of programming cycles. This limitation is meaningless for ‘read-only’ applications such as thin clients and routers, which are programmed only once or at most a few times during their lifetimes.
Reliability and warranty: It’s vital that a card reader works the way it’s meant to. We tested a surprising number of units in this category that were defective or performed inconsistently. For this reason, we favor readers from trustworthy manufacturers with solid warranties—most USB-C card readers that we found had one-year warranties, but two- and three-year warranties are even better.
By repeating deletion and write of files, data area is gradually fragmented and it influences write speed. Generally, write speed to a fragmented area is slower than sequential write speed due to flash memory characteristics. In an era when memory capacity is not large enough, fragmented write needed to be considered. However, high capacity memory card is available at this time, Speed Class write is defined to perform sequential writes to a completely un-fragmented area (called “Free AU”). It makes Speed Class controls of host easy. On the other hand, even unused memory exists in total, there is a possibility that host cannot perform Speed Class recording. In that case, data arrangement to reduce fragmented area or move data to anther storage to re-format the card will be required. Video Speed Class supports “Suspend/Resume” function that can stop and retrieve sequential write. By using the function, it is possible to improve memory usage ratio considerably.

In 2006, the SDA released a simplified version of the specification of the host controller interface (as opposed to the specification of SD cards) and later also for the physical layer, ASSD extensions, SDIO, and SDIO Bluetooth Type-A, under a disclaimers agreement.[116] Again, most of the information had already been discovered and Linux had a fully free driver for it. Still, building a chip conforming to this specification caused the One Laptop per Child project to claim “the first truly Open Source SD implementation, with no need to obtain an SDI license or sign NDAs to create SD drivers or applications.”[117]

The SDA announced the microSD format at CTIA Wireless 2005 on March 14, 2005, and the final microSD details were announced on July 13, 2005. When they were first sold, the microSD format was sold in sizes of 32, 64, and 128 MB. SanDisk made a 4 GB microSD card on July 2006, at first costing $99 (USD). Since then, the prices for flash memory devices have become much lower. At the time of April 2009, the same 4 GB card could be bought for as low as $12 (USD) at department stores, and by May 2009, for as low as $6 (USD) at online electronics stores. In January 2010, a 16 GB micro SD card class 2 cost about $40 (USD), and a 4 GB class 2 micro SD card about $8 (USD).
Flash memory is a non-volatile memory chip used for storage and for transfering data between a personal computer (PC) and digital devices. It has the ability to be electronically reprogrammed and erased. It is often found in USB flash drives, MP3 players, digital cameras and solid-state drives.
I bought this during black friday and I got a huge discount using my rewards points also. I primarlly use it for my Galaxy Note 2. After 2 months, the phone says that the sd card was unexpectedly unmouted. Then my card was not recognized and blank. I could not reformat it in any way since my computer and any other devices can not recognize it. After a successfull fix, 2 days later same thing happen and now I can not get it to work at all. I do not know who to get a hold on to get this fixed. But it is a bummer since I it is a nice size and value. But it just failed horribly.
When it comes to flash memory cards, there are three aspects you need to consider: physical format, size, and speed. Each of the three variables has its own set of classes, so you can have anything from a 1GB Class 2 microSD card to a 32GB UHS-1 SDXC card. We’ll explore the distinctions below.
Windows Vista (SP1) and later[21] and OS X (10.6.5 and later) support exFAT out of the box.[22][23] (Windows XP and Server 2003 can support exFAT via an optional update from Microsoft.)[24] Most BSD and Linux distributions do not, for legal reasons; users must manually install third-party implementations of exFAT (as a FUSE module) in order to be able to mount exFAT-formatted volumes.[25] However, SDXC cards can be reformatted to use any file system (such as ext2, UFS, or VFAT), alleviating the restrictions associated with exFAT availability.
Compatibility with SD and CF cards: There are a wide variety of memory card formats, but the most prominent are Secure Digital (SD), microSD, and CompactFlash (CF). We looked for readers that support SD and CF cards to ensure compatibility with as many cameras as possible; although most people don’t need CF support nowadays, we considered them for professionals and people with older cameras. We also tried to find readers that support faster UHS-II speeds for SD cards,1 but couldn’t find any USB-C readers with both UHS-II support and a CF card slot.
The fastest memory card seems to chance from week to week and several companies claim they have the “fastest”, but UDMA (Ultra Direct Memory Access) Cfast 2.0 cards are the current front runners – with speeds of over 500MB/sec. However, these are really yet to be available for more than a narrow selection of cameras and remain highly expensive.
As discussed above, the memory card options available to you are limited by the device you are using it in. Each device has a discrete set of compatible card choices. Check your device carefully, as many cameras have multiple memory card slots, giving you more options of what cards you can use.
A hybrid flash array blends disk and SSDs. Hybrid arrays use SSDs as a cache to speed access to frequently requested hot data, which subsequently is rewritten to back-end disk. Many enterprises commonly archive data from disk as it ages by replicating it to an external magnetic tape library.
Flash memory incorporates the use of floating-gate transistors to store data. Floating-gate transistors, or floating gate MOSFET (FGMOS), is similar to MOSFET, which is a transistor used for amplifying or switching electronic signals. Floating-gate transistors are electrically isolated and use a floating node in direct current (DC). Flash memory is similar to the standard MOFSET, except the transistor has two gates instead of one.
If you need a USB-A card reader, or a reader that can take both CF cards and high-speed UHS-II SD cards, the Kingston USB 3.0 High-Speed Media Reader is your best bet. The Kingston supports SD, microSD, CF, and Memory Stick cards, and it reliably transferred data at UHS-II speeds in our SD card tests. It also has a big red indicator light, and comes with a two-year warranty.
Electrons are trapped in the floating gate whether or not a device containing the flash memory cell is receiving power as a result of electrical isolation created by the oxide layer. This characteristic enables flash memory to provide persistent storage.
Flash memory architecture includes a memory array stacked with a large number of flash cells. A basic flash memory cell consists of a storage transistor with a control gate and a floating gate, which is insulated from the rest of the transistor by a thin dielectric material or oxide layer. The floating gate stores the electrical charge and controls the flow of the electrical current. 
SDXC cards are allowed to use all 22 bits of the C_SIZE field. An SDHC card that did so (reported C_SIZE > 65375 to indicate a capacity of over 32 GB) would violate the specification. A host device that relied on C_SIZE rather than the specification to determine the card’s maximum capacity might support such a card, but the card might fail in other SDHC-compatible host devices.
Devices using flash memory erase data at the block level and rewrite data at the byte level — NOR flash — or multiple-byte page level — NAND flash. Flash memory is widely used for storage and data transfer in consumer devices, enterprise systems and industrial applications.

Early SDSC host devices that assume 512-byte blocks therefore do not fully support the insertion of 2 GB or 4 GB cards. In some cases, the host device can read data that happens to reside in the first 1 GB of the card. If the assumption is made in the driver software, success may be version-dependent. In addition, any host device might not support a 4 GB SDSC card, since the specification lets it assume that 2 GB is the maximum for these cards.[citation needed]
Flash memory was first introduced in 1980 and developed by Dr. Fujio Masuoka, an inventor and mid level factory manager at Toshiba Corporation (TOSBF). Flash memory was named after its capability to erase a block of data “”in a flash.” Dr. Masuoka’s objective was to create a memory chip preserving data when the power was turned off. Dr. Masuoka also invented a type of memory known as SAMOS and developed a 1Mb dynamic random access memory (DRAM). In 1988, Intel Corporation produced the first commercial NOR-type flash chip, which replaced the permanent read-only memory (ROM) chip on PC motherboards containing the basic input/output operating system (BIOS).

With early SD cards, a few card manufacturers specified the speed as a “times” (“×”) rating, which compared the average speed of reading data to that of the original CD-ROM drive. This was superseded by the Speed Class Rating, which guarantees a minimum rate at which data can be written to the card.[34]
The SD card specification defines three physical sizes. The SD and SDHC families are available in all three sizes, but the SDXC family is not available in the mini size, and the SDIO family is not available in the micro size. Smaller cards are usable in larger slots through use of a passive adapter.
The Kingston had read and write speeds of 159 MB/s and 127 MB/s, respectively, during our SD card test. In our microSD card test, it had expected read and write speeds of 83 MB/s and 69 MB/s. It was a bit slower when reading and writing to a CF card, with speeds of 127 MB/s and 107 MB/s.
I’m not a tech wiz but I’m by no means a complete moron when it comes to technology but I was somewhat distressed to find how little I knew about memory cards. I had received one with a little no frills digital camera a few years ago & had used them already but a recent faux pas brought my ignorance to light. I was at one of my daughter’s competitions with my little Panasonic video camera intending to record her show (she does color guard). We had bought the video camera a couple of years ago. It needed a memory card so I just took the one out of my other camera thinking that’s what I needed. Here’s where not realizing the difference between MB and GB ruined my plans.Trying to record the show, I kept getting the message that the memory was full. Turns out… The card was just 512MB! Those of you in the know are laughing I’m sure…yep, that may be fine for photos but NOT video..So after finding out 1 GB is roughly the same as 1000 MB, I knew what to look for. This card has a good amount of memory. I’ve recorded several of my daughter’s routines and still show as having just under half the memory available. I also have found that you get what you pay for. I bought a generic card that didn’t work and another that got corrupted quickly so I only trust SanDisk now! My next step is getting a 32GB and having a backup card at all times!
Not sure what the difference is between a £50 Class 2 SD and a £450 Class 10 SDHC memory card? We’ve split them up into their categories and broken down the speed jargon by translating it into real speed ratings so you can decide if a certain memory card is worth the extra money.

NOR flash is more expensive to produce than NAND flash and tends to be used primarily in consumer and embedded devices for boot purposes and read-only applications for code storage. NAND flash is more suitable for data storage in consumer devices and enterprise server and storage systems due to its lower cost per bit to store data, greater density, and higher programming and erase (P/E) speeds.
If you just bought a brand-new laptop and suddenly find yourself lacking a built-in SD reader, you may need a USB-C model. All of the latest MacBooks (including the 2016 and 2017 MacBook Pro models) have only USB-C ports, and no SD card readers. Some new Windows laptops exclusively use USB-C ports, too, and others have a mix of USB types and no built-in SD card slot.
Micro SD cards were initially a popular method of storing images in mobile phones. In actual size they are the smallest commercially available memory card at 15×11×1mm but can store up to 2GB of information. The Micro SDHC versions are able to store much larger files from 4GB-32GB. Micro SD cards are now more commonly seen in GPS systems and MP3 players, however a small number of digital cameras (recent Samsung compact models) are also compatible with them.
When you insert a memory card, it is automatically mounted (connected to the device) and prepared for use. However, should you unmount the card without removing it from the device, you will need to mount it before it can be accessed.
It’s the most compact card reader we tested, measuring 2.4 by 1 by 0.4 inches and weighing just 0.3 ounces. The Cable Matters also has an attached, 6-inch cable and a pleasant blue indicator light on top so you know when it’s in use. In testing we found—after wasting time trying to insert them right-side up—that the slots are oriented so you have to insert both SD cards and microSD cards upside down for the card reader to identify them. Once you’ve loaded your microSD and SD cards, you have to flip the card reader back around to see its indicator light.
The Hyperdrive 3-in-1 Connection Kit gave us SD read and write speeds of 20 MB/s, though we should have been getting at least 80 MB/s on a UHS-I connection. And its design obstructs other plugs—most notably blocking the power plug on a Dell XPS 13, and the only other port on the MacBook Pro (13-inch, late 2016, Two Thunderbolt 3 Ports).

SDXC cards are allowed to use all 22 bits of the C_SIZE field. An SDHC card that did so (reported C_SIZE > 65375 to indicate a capacity of over 32 GB) would violate the specification. A host device that relied on C_SIZE rather than the specification to determine the card’s maximum capacity might support such a card, but the card might fail in other SDHC-compatible host devices.
In the definition of SDHC cards in version 2.0, the C_SIZE portion of the CSD is 22 bits and it indicates the memory size in multiples of 512 KB (the C_SIZE_MULT field is removed and READ_BL_LEN is no longer used to compute capacity). Two bits that were formerly reserved now identify the card family: 0 is SDSC; 1 is SDHC or SDXC; 2 and 3 are reserved.[30] Because of these redefinitions, older host devices do not correctly identify SDHC or SDXC cards nor their correct capacity.
Speaking more generally, CompactFlash (CF) cards on the market can have a speed rating of 150MB/sec (1000x) and will work for a large variety of cameras, while most standard SDHC cards currently tend to be around 20-30MB/sec (133-200x). While there are also a few super-fast UHS-II U3 SDHC cards available now with potential write speeds of 250MB/s, these are also not as widely available for use in all cameras and do start to get rather pricey.
Nintendo developed stereoscopic 3D technology for the GameCube, and one launch game, Luigi’s Mansion, supports it. However, the feature was never enabled outside of development. 3D televisions were not widespread at the time, and it was deemed that compatible displays and crystals for the add-on accessories would be too cost-prohibitive for the consumer.[43][44][45] Another unofficial feature are two audio Easter eggs that can be invoked when the console is turned on. When the power is activated with the “Z” button on the Player 1 controller held down, a more whimsical startup sound is heard in place of the standard one. With four controllers connected, holding down the “Z” button on all four simultaneously produces a “ninja-like” tune at startup.[46]
After a new round of research and testing, we found that the Unitek USB-C Card Reader is the best USB-C SD card reader for most people. Our previous pick, the Iogear USB-C 3-Slot Card Reader, is now our runner-up. We have a new, less-expensive UHS-II SD reader recommendation, the Verbatim USB-C Pocket Card Reader, and our budget and USB-A picks remain the same.
The memory card market does sometimes seem overcomplicated, but if there’s one thing you need to remember from this article then it’s this: image quality is completely unaffected by your choice of memory card.
The Kingston had read and write speeds of 159 MB/s and 127 MB/s, respectively, during our SD card test. In our microSD card test, it had expected read and write speeds of 83 MB/s and 69 MB/s. It was a bit slower when reading and writing to a CF card, with speeds of 127 MB/s and 107 MB/s.
The Iogear is about an inch skinnier and a half inch longer than the Unitek, measuring in at 3 by 1.6 by 0.5 inches. Although it’s technically shorter and lighter than the Unitek, its rounded top makes it appear bulkier. It also has a shiny black body that attracts fingerprints, and a short, 4.3-inch connecting cable attached to its back.

Bottom line, some of them (namely, the old 30-pin SD card reader combined with a Lightning-to-30-pin converter) no longer work after upgrading to iOS 11. I’m with you, folks — the obsolescence of the old “Camera Kit” hardware is a sad thing. But, it’s time for us all to get over it and upgrade to the new hardware — you’ll be so glad once you have.

NAND flash has reduced erase and write times, and requires less chip area per cell, thus allowing greater storage density and lower cost per bit than NOR flash; it also has up to 10 times the endurance of NOR flash. However, the I/O interface of NAND flash does not provide a random-access external address bus. Rather, data must be read on a block-wise basis, with typical block sizes of hundreds to thousands of bits. This makes NAND flash unsuitable as a drop-in replacement for program ROM, since most microprocessors and microcontrollers require byte-level random access. In this regard, NAND flash is similar to other secondary data storage devices, such as hard disks and optical media, and is thus highly suitable for use in mass-storage devices, such as memory cards. The first NAND-based removable media format was SmartMedia in 1995, and many others have followed, including:
The GameCube is unable to play games from other Nintendo home consoles, but with the Game Boy Player attachment, it is able to play Game Boy, Game Boy Color, and Game Boy Advance games. The GameCube’s successor, the Wii, supports backward compatibility with GameCube controllers, memory cards, and games. However, later versions of the Wii – including the “Family Edition” released in 2011 and the Wii Mini edition released in 2012 – dropped support for all GameCube hardware.[56][57][58]
Micro SD cards were initially a popular method of storing images in mobile phones. In actual size they are the smallest commercially available memory card at 15×11×1mm but can store up to 2GB of information. The Micro SDHC versions are able to store much larger files from 4GB-32GB. Micro SD cards are now more commonly seen in GPS systems and MP3 players, however a small number of digital cameras (recent Samsung compact models) are also compatible with them.
An additional subcategory is a hybrid hard drive that combines a conventional HDD with a NAND flash module. A hybrid hard drive is generally viewed as a way to bridge the divide between rotating media and flash memory.
Electrons are trapped in the floating gate whether or not a device containing the flash memory cell is receiving power as a result of electrical isolation created by the oxide layer. This characteristic enables flash memory to provide persistent storage.
Works very well for a third party GC memory card. Used it for about a week and not a single game file has corrupted. If you’re looking for a 1019 block GC memory card but don’t want to shell out the $20, this is what you’re looking for.
If your camera uses SD cards but your laptop lacks a card reader (or it has one, and you’re unimpressed by its speed), you’ll need a separate card reader that hooks up to your laptop via USB-C or USB-A to transfer your photos and videos.
I bought this card for my Samsung Galaxy S II (T-Mobile T-989) and couldn’t be happier. I’ve got about 15 games, 10 apps, and 200+ songs on it and barely put a dent in it. The speed is also amazing…real fast. I work in a very dusty construction type environment in Michigan, outdoors, year-round, so the durability is also a nice plus. Water resistant (submersed) for up to 72 hrs and temp range of -13 to 185. Sandisk really got it right with this one.

If you are interested in an SD card for a DSLR, look at something like the Lexar Professional 600x 32GB SDHC UHS-I Flash Memory Card LSD32GCRBNA600. Since switching to the C10/U1 Lexar, I’ve been infinitely more happy with my camera. The Sandisk C4 32GB remains in my point and shoot, where it’s better suited.
In 2008, the SDA specified Embedded SD, “leverag[ing] well-known SD standards” to enable non-removable SD-style devices on printed circuit boards.[98] However this standard was not adopted by the market while the MMC standard became the de facto standard for embedded systems. SanDisk provides such embedded memory components under the iNAND brand.[99]

Most SD cards ship preformatted with one or more MBR partitions, where the first or only partition contains a file system. This lets them operate like the hard disk of a personal computer. Per the SD card specification, an SD card is formatted with MBR and the following file system:
A host device can ask any inserted SD card for its 128-bit identification string (the Card-Specific Data or CSD). In standard-capacity cards (SDSC), 12 bits identify the number of memory clusters (ranging from 1 to 4,096) and 3 bits identify the number of blocks per cluster (which decode to 4, 8, 16, 32, 64, 128, 256, or 512 blocks per cluster). The host device multiplies these figures (as shown in the following section) with the number of bytes per block to determine the card’s capacity in bytes.[citation needed]
These cards are each pre-packed in a certified Frustration Free Packaging (FFP) mailer labelled Amazon/SanDisk (No. 80-56-10641), and then shipped in a bubble wrap envelope which was 11.25″ x 9″. The bubble envelope seemed too big, but perhaps that size was necessary to accommodate the huge shipping label. I will post some pictures of the package and card.
Nevertheless, in order to be fully compliant with the SDXC card specification, many SDXC-capable host devices are firmware-programmed to expect exFAT on cards larger than 32 GB[citation needed]. Consequently, they may not accept SDXC cards reformatted as FAT32, even if the device supports FAT32 on smaller cards (for SDHC compatibility). Therefore, even if a file system is supported in general, it is not always possible to use alternative file systems on SDXC cards at all depending on how strictly the SDXC card specification has been implemented in the host device. This bears a risk of accidental loss of data, as a host device may treat a card with an unrecognized file system as blank or damaged and reformat the card.
The GameCube introduced a proprietary miniDVD optical disc format as the storage medium for the console, capable of storing up to 1.5 GB of data.[37] The technology was designed by Matsushita Electric Industrial (now Panasonic Corporation) which utilizes a proprietary copy-protection scheme – different from the Content Scramble System (CSS) found in standard DVDs – to prevent unauthorized reproduction.[38] The Famicom Data Recorder, Famicom Disk System, SNES-CD, and 64DD had explored various complementary storage technologies, but the GameCube was Nintendo’s first console to move away from cartridge-based media altogether.[39] The GameCube’s 1.5 GB mini-disc have sufficient room for most games, although a few games require an extra disc, higher video compression, or removal of content present in versions on other consoles. By comparison, the PlayStation 2 and Xbox, also sixth-generation consoles, both use 8.5 GB Dual-Layer DVDs.
Many personal computers of all types, including tablets and mobile phones, use SD cards, either through built-in slots or through an active electronic adapter. Adapters exist for the PC card, ExpressBus, USB, FireWire, and the parallel printer port. Active adapters also let SD cards be used in devices designed for other formats, such as CompactFlash. The FlashPath adapter lets SD cards be used in a floppy disk drive.

It’s the most compact card reader we tested, measuring 2.4 by 1 by 0.4 inches and weighing just 0.3 ounces. The Cable Matters also has an attached, 6-inch cable and a pleasant blue indicator light on top so you know when it’s in use. In testing we found—after wasting time trying to insert them right-side up—that the slots are oriented so you have to insert both SD cards and microSD cards upside down for the card reader to identify them. Once you’ve loaded your microSD and SD cards, you have to flip the card reader back around to see its indicator light.

As of 2013, V-NAND flash architecture allows read and write operations twice as fast as conventional NAND and can last up to 10 times as long, while consuming 50 percent less power. They offer comparable physical bit density using 10-nm lithography, but may be able to increase bit density by up to two orders of magnitude.[24]
Yes. To save Nintendo GameCube games, you must have a Nintendo GameCube Memory Card inserted into one of the Nintendo GameCube Memory Card slots of your Wii. Please note that you cannot save GameCube game data to your Wii’s internal flash memory or to an SD card.
On ASUS systems there are USB port issues going on since Windows 8.1. Since SD card reader on these ASUS models is off USB, can you please try the following which is uninstall AI Suite software as suggested in the following blog:
NAND flash also uses floating-gate transistors, but they are connected in a way that resembles a NAND gate: several transistors are connected in series, and the bit line is pulled low only if all the word lines are pulled high (above the transistors’ VT). These groups are then connected via some additional transistors to a NOR-style bit line array in the same way that single transistors are linked in NOR flash.

Common flash devices such as USB flash drives and memory cards provide only a block-level interface, or flash translation layer (FTL), which writes to a different cell each time to wear-level the device. This prevents incremental writing within a block; however, it does help the device from being prematurely worn out by intensive write patterns.

I bought this during black friday and I got a huge discount using my rewards points also. I primarlly use it for my Galaxy Note 2. After 2 months, the phone says that the sd card was unexpectedly unmouted. Then my card was not recognized and blank. I could not reformat it in any way since my computer and any other devices can not recognize it. After a successfull fix, 2 days later same thing happen and now I can not get it to work at all. I do not know who to get a hold on to get this fixed. But it is a bummer since I it is a nice size and value. But it just failed horribly.
If your camera uses SD cards but your laptop lacks a card reader (or it has one, and you’re unimpressed by its speed), you’ll need a separate card reader that hooks up to your laptop via USB-C or USB-A to transfer your photos and videos.
If the SD card is integrated, the drivers for it will be amongst the motherboard drivers. Have you tried looking at the motherboard manufacturers website? Often times that driver will be bundled with other drivers.

With the increasing speed of modern CPUs, parallel flash devices are often much slower than the memory bus of the computer they are connected to. Conversely, modern SRAM offers access times below 10 ns, while DDR2 SDRAM offers access times below 20 ns. Because of this, it is often desirable to shadow code stored in flash into RAM; that is, the code is copied from flash into RAM before execution, so that the CPU may access it at full speed. Device firmware may be stored in a serial flash device, and then copied into SDRAM or SRAM when the device is powered-up.[71] Using an external serial flash device rather than on-chip flash removes the need for significant process compromise (a process that is good for high-speed logic is generally not good for flash and vice versa). Once it is decided to read the firmware in as one big block it is common to add compression to allow a smaller flash chip to be used. Typical applications for serial flash include storing firmware for hard drives, Ethernet controllers, DSL modems, wireless network devices, etc.
Store several gigabytes of data in a small form factor. Supports the latest in memory card format, SDXC (Secure Digital Extended Capacity). Provides two different memory card slots: whether you have the SD or MicroSD size memory card, the dual slot IOGEAR Card Reader/Writer has got you covered.
SDHC cards are physically and electrically identical to standard-capacity SD cards (SDSC). The major compatibility issues between SDHC and SDSC cards are the redefinition of the Card-Specific Data (CSD) register in version 2.0 (see below), and the fact that SDHC cards are shipped preformatted with the FAT32 file system.

If our pick is out of stock or unavailable, we recommend the Iogear USB-C 3-Slot Card Reader. It was fast and reliable in all of our tests, it supports SD, microSD, and CF cards, and it’s slim and light. But it lacks an indicator light, it’s less intuitive to use, and it’s usually a little more expensive than our top pick, the Unitek. Iogear includes a three-year warranty, longer than that of any of its competitors.

Dr. Fujio Masuoka is credited with the invention of flash memory when he worked for Toshiba in the 1980s. Masuoka’s colleague, Shoji Ariizumi, reportedly coined the term flash because the process of erasing all the data from a semiconductor chip reminded him of the flash of a camera.

Your computer may not have the right memory card reader built in, or have any card reader at all. Card readers are simple-to-use, portable attachments you can plug in to a USB port to transfer your photos and videos from your memory card. Card readers come in a wide variety with different combinations of memory card ports.

Reliability and warranty: It’s vital that a card reader works the way it’s meant to. We tested a surprising number of units in this category that were defective or performed inconsistently. For this reason, we favor readers from trustworthy manufacturers with solid warranties—most USB-C card readers that we found had one-year warranties, but two- and three-year warranties are even better.

File fragmentation: where there is not sufficient space for a file to be recorded in a contiguous region, it is split into non-contiguous fragments. This does not cause rotational or head-movement delays as with electromechanical hard drives, but may decrease speed; for instance, by requiring additional reads and computation to determine where on the card the file’s next fragment is stored.
Cards often have a multiplication factor written on them which usually represents read speed (such as 133x, 200x, 300x, etc). This is called the ‘Commercial x rating’ with 1x being equivalent to the speed of the original CD-ROM of 150 KB/sec. This makes it easy to convert between the two by multiplying or dividing by 150. So, 200x will equate to 1 seconds to read a 29.5MB image file (200 x 150 = 30,000/1016 = 29.528).
Version 1.01 let an SDSC card use a 4-bit field to indicate 1,024 or 2,048 bytes per block instead.[30] Doing so enabled cards with 2 GB and 4 GB capacity, such as the Transcend 4 GB SD card and the Memorette 4GB SD card.
While larger is better, you need to make sure your device can use the larger card. The SD/SDHC/SDXC classification isn’t just for cards, but for devices as well. Older digital cameras can only read SD cards, making SDHC cards useless. Similarly, cameras that aren’t SDXC-compatible won’t accept 64GB cards. Most current devices are SDHC compatible, but double-check your older devices before getting SDHC cards, and check the specs on your newer gear before getting SDXC cards.
Hamming codes are the most commonly used ECC for SLC NAND flash. Reed-Solomon codes and Bose-Chaudhuri-Hocquenghem codes are commonly used ECC for MLC NAND flash. Some MLC NAND flash chips internally generate the appropriate BCH error correction codes.[37]
UHS-II standard SDHC/SDXC cards were recently released by Sandisk and aim to offer quicker transfer rates, increasing write speeds up to 250MB/s or faster. The Sandisk Extreme Pro cards match up with the sheer amount of data streaming through the camera’s buffer when shooting lots of Raw files or high quality HD movies. Prices can range between around £50-£150 depending on the capacity (currently 16-64GB).
Many of Nintendo’s own first-party games, such as Super Smash Bros. Melee and Mario Kart: Double Dash‼, saw strong sales, though this did not typically benefit third-party developers or directly drive sales of their games. Many cross-platform games — such as sports franchises released by Electronic Arts — were sold in numbers far below their PlayStation 2 and Xbox counterparts, eventually prompting some developers to scale back or completely cease support for the GameCube. Exceptions include Sega’s family friendly Sonic Adventure 2 and Super Monkey Ball, which reportedly yielded more sales on GameCube than most of the company’s games on the PlayStation 2 and Xbox.[20] After several years of losing money from developing for Nintendo’s console, Eidos Interactive announced in September 2003 that it would end support for the GameCube, canceling several games that were in development.[87] Later, however, Eidos resumed development[88] of GameCube games, releasing hit games such as Lego Star Wars: The Video Game and Tomb Raider: Legend. In addition, several third-party games originally intended to be GameCube exclusives – most notably Resident Evil 4 – were eventually ported to other systems in an attempt to maximize profits following lackluster sales of the original GameCube versions.
Flash memory is extremely small, fast, lightweight, and makes no noise or have any moving parts, unlike hard drives. However, hard disks can hold considerably more data and its cost per megabyte is much cheaper although prices are quickly dropping as capacity grows larger for flash devices daily. Yet flash memory is quite reliable and allows you to specify which data you want to keep.
NAND devices also require bad block management by the device driver software, or by a separate controller chip. SD cards, for example, include controller circuitry to perform bad block management and wear leveling. When a logical block is accessed by high-level software, it is mapped to a physical block by the device driver or controller. A number of blocks on the flash chip may be set aside for storing mapping tables to deal with bad blocks, or the system may simply check each block at power-up to create a bad block map in RAM. The overall memory capacity gradually shrinks as more blocks are marked as bad.

V-NAND uses a charge trap flash geometry (pioneered in 2002 by AMD)[citation needed] that stores charge on an embedded silicon nitride film. Such a film is more robust against point defects and can be made thicker to hold larger numbers of electrons. V-NAND wraps a planar charge trap cell into a cylindrical form.[24]
Flash memory, also known as flash storage, is a type of nonvolatile memory that erases data in units called blocks. A block stored on a flash memory chip must be erased before data can be written or programmed to the microchip. Flash memory retains data for an extended period of time, regardless of whether a flash-equipped device is powered on or off.
NAND sacrifices the random-access and execute-in-place advantages of NOR. NAND is best suited to systems requiring high capacity data storage. It offers higher densities, larger capacities, and lower cost. It has faster erases, sequential writes, and sequential reads.

We were really surprised with this little USB SD/Micro SD/MMC reader. The design is reminiscent of older USB flash sticks and as such may be a little awkward when used on a laptop machine in one’s lap. It comes complete with a small cap to go over the USB port, and like flash sticks, can get lost quite easily, but that’s all we could find to complain about.
A new generation of memory card formats, including RS-MMC, miniSD and microSD, feature extremely small form factors. For example, the microSD card has an area of just over 1.5 cm2, with a thickness of less than 1 mm. As of August 2017 microSD cards with capacity up to 400GB are available.[11][12]

Nintendo sold 22 million GameCube units worldwide during its lifespan,[5][81] placing it slightly behind the Xbox’s 24 million,[82] and well behind the PlayStation 2’s 153 million.[83] The GameCube’s predecessor, the Nintendo 64, outperformed it as well selling nearly 33 million units.[84] The console was able to outsell the short-lived Dreamcast, however, which yielded 9.13 million unit sales.[85] In September 2009, IGN ranked the GameCube 16th in its list of best gaming consoles of all time, placing it behind all three of its sixth-generation competitors: the PlayStation 2 (3rd), the Dreamcast (8th), and the Xbox (11th).[72] As of March 31, 2003, the GameCube had sold 9.55 million units worldwide, falling short of Nintendo’s initial goal of 10 million consoles.[86]
An additional subcategory is a hybrid hard drive that combines a conventional HDD with a NAND flash module. A hybrid hard drive is generally viewed as a way to bridge the divide between rotating media and flash memory.
You may not know, but not all devices are compatible with SD cards of 128GB, as well as not all devices support different classes and versions of external memories on the market. So, Taking a look at the capacity is very important since you do not want to end up with a card that your device doesn’t support.
Well, Nintendo’s most recent official confirmation about the production of the GC was revealed only 2 months ago. And they said it’s still produced. If it was out of production, don’t you think they would say something? They haven’t said anything about the GC since then. Again, the last time they did they said it’s still produced and that wasn’t very long ago.

Early versions of the SD specification were available only after agreeing to a non-disclosure agreement (NDA) that prohibited development of an open source driver. However, the system was eventually reverse-engineered, and free software drivers provided access to SD cards that did not use DRM. Since then, the SDA has provided a simplified version of the specification under a less restrictive license.[115] Although most open-source drivers were written before this, it has helped to solve compatibility issues.
Initiating the GameCube’s design in 1998, Nintendo partnered with ArtX (then acquired by ATI Technologies during development) for the system logic and the GPU,[9] and with IBM for the CPU. IBM designed a PowerPC-based processor for the next-generation console, known as Gekko, which runs at 485 MHz and features a floating point unit (FPU) capable of 1.9 GFLOPS. Designed at 0.18 microns and described as “an extension of the IBM Power PC architecture”, Gekko features IBM’s reportedly then-unique copper-based chip manufacturing technology.[8] Codenamed “Flipper”, the GPU runs at 162 MHz and, in addition to graphics, manages other tasks through its audio and input/output (I/O) processors.[33][34][35][36]

In Japan, between 280,000 and 300,000 GameCube consoles were sold during the first three days of its sale, out of an initial shipment of 450,000 units.[76] During its launch weekend, the GameCube sold $100 million worth of GameCube products in North America.[77] The console was sold out in several stores, selling faster than both of its competitors, the Xbox and the PlayStation 2, has initially sold.[78] The most popular game at the system’s launch was Luigi’s Mansion, which, according to Nintendo, sold more at launch than Super Mario 64 had.[79] Other popular games include Star Wars Rogue Squadron II: Rogue Leader And Wave Race: Blue Storm.[77] By early December 2001, the system had sold 600,000 units in the US.[80]
With the GameCube, Nintendo failed to reclaim the market share lost by its predecessor, the Nintendo 64. Throughout the lifespan of its console generation, GameCube hardware sales remained far behind its direct competitor the PlayStation 2, and slightly behind Microsoft’s Xbox. The console’s “family-friendly” appeal and lack of support from certain third-party developers skewed the GameCube toward a younger market, which was a minority demographic of the gaming population during the sixth generation.[96] Many third-party games popular with teenagers or adults, such as the blockbuster Grand Theft Auto series and several key first-person shooters, skipped the GameCube entirely in favor of the PlayStation 2 and Xbox.
These two are linked by the design choices made in the development of NAND flash. A goal of NAND flash development was to reduce the chip area required to implement a given capacity of flash memory, and thereby to reduce cost per bit and increase maximum chip capacity so that flash memory could compete with magnetic storage devices like hard disks.[citation needed]

SD cards are also available in various speeds. If you’re using a point-and-shoot digital camera or a standard-definition pocket camcorder, speed class won’t matter much. If you’re shooting high-resolution RAW photos with a digital SLR, however, you need a quick card to take more than two or three shots at a time. SD cards are generally described by their Speed Class, ranging from Class 2 (slowest) to Class 10 (fastest). There’s also a separate, even faster category called UHS Class 1 (for Ultra High Speed), but most current devices can’t use them.
SDHC card: This card has the same form factor as an SD card, with specifications that define SDHC card capacities from 4 GB to 32 GB. These devices were developed to tackle high-definition video and high-resolution images. Although SD cards will work in an SDHC device, an SDHC card will not function in an SD card-based digital camera or card reader.

Most will convert to JPG at this time. I’m using the piRAWnha app but there are others. Even the current Adobe apps for iOS will only work with JPG files—Lightroom and Photoshop Fix are the two I tested. More(Read full review)
Video Speed Class is defined to answer a demand for high resolution and high quality 4K8K video recording and it also has an important feature to support next generation flash memory such as 3D NAND. Furthermore, as it covers speed of HD(2K) video, it is possible to integrate into Video Speed Class from now on.
Like the SanDisk, StarTech’s USB-C Dual UHS-II Card Reader supports UHS-II performance and does not have a microSD card slot. It’s much wider and longer than the competition, and it costs almost 2.5 times the price of the Verbatim for similar performance. It can read two SD cards simultaneously, although you lose some speed in the process.
It was designed to compete with the Memory Stick, a DRM product that Sony had released the year before. Developers predicted that DRM would induce wide use by music suppliers concerned about piracy.[59]

File fragmentation: where there is not sufficient space for a file to be recorded in a contiguous region, it is split into non-contiguous fragments. This does not cause rotational or head-movement delays as with electromechanical hard drives, but may decrease speed; for instance, by requiring additional reads and computation to determine where on the card the file’s next fragment is stored.

A card’s read speed describes how fast data can be retrieved from a card. This performance is seen when transferring card contents to computers and printers for example. A faster read speed will transfer images to your computer more rapidly also (depending on how the SD card is wired up to the computer, as a direct connection vs USB 2 vs FireWire 800 vs USB 3 will make a significant difference also, as will, potentially, your hard disk or SSD storage memory speed).
When capturing images and videos with your camera, camcorder, drone, or select mobile device, you may need a memory card. Memory cards act as storage for your devices, capturing photographs or even 4K Ultra HD video. The more complex your images or videos — such as shooting burst photographs, fast action shots or high-definition videos — the faster and larger your memory card needs to be. When shopping for the right memory card, you’ll want to make sure it is compatible, and has the capacity and speed to support your device.
The GameCube is unable to play games from other Nintendo home consoles, but with the Game Boy Player attachment, it is able to play Game Boy, Game Boy Color, and Game Boy Advance games. The GameCube’s successor, the Wii, supports backward compatibility with GameCube controllers, memory cards, and games. However, later versions of the Wii – including the “Family Edition” released in 2011 and the Wii Mini edition released in 2012 – dropped support for all GameCube hardware.[56][57][58]
The Video Speed Classes defined by the SD Association are V6, 10,30,60 and 90. V6 and V10 can be applied to High Speed and UHS Bus IF product family. V30 can be applied to UHS Bus IF product family. V60 and V90 can be applied to UHS-II / UHS-III product family.

SDHC card: This card has the same form factor as an SD card, with specifications that define SDHC card capacities from 4 GB to 32 GB. These devices were developed to tackle high-definition video and high-resolution images. Although SD cards will work in an SDHC device, an SDHC card will not function in an SD card-based digital camera or card reader.
There are two major SPI flash types. The first type is characterized by small pages and one or more internal SRAM page buffers allowing a complete page to be read to the buffer, partially modified, and then written back (for example, the Atmel AT45 DataFlash or the Micron Technology Page Erase NOR Flash). The second type has larger sectors. The smallest sectors typically found in an SPI flash are 4 kB, but they can be as large as 64 kB. Since the SPI flash lacks an internal SRAM buffer, the complete page must be read out and modified before being written back, making it slow to manage. SPI flash is cheaper than DataFlash and is therefore a good choice when the application is code shadowing.
If you use a camera or cards that support UHS-II speeds, we recommend the Verbatim USB-C Pocket Card Reader. The Verbatim had read and write speeds of 227 MB/s and 219 MB/s, respectively—around 2.5 times the speed of our top pick—but it cannot read multiple cards at once. It also lacks a CF card slot (so high-end DSLR owners may want to look at our pick for traditional USB ports, along with an adapter if they need USB-C compatibility) and an indicator light, but it costs around the same price as our top pick and comes with a one-year warranty.
ArtX was acquired by ATI in April 2000, whereupon the Flipper graphics processor design had already been mostly completed by ArtX and was not overtly influenced by ATI.[7][9] In total, ArtX team cofounder Greg Buchner recalled that their portion of the console’s hardware design timeline had arced from inception in 1998 to completion in 2000.[7] Of ATI’s acquisition of ArtX, an ATI spokesperson said, “ATI now becomes a major supplier to the game console market via Nintendo. The Dolphin platform is reputed to be king of the hill in terms of graphics and video performance with 128-bit architecture.”[12]
I am using this memory card for saving Gamecube games on my softmodded Wii. I am USB loading the games with Dios-Mios. That being said, I doubt that it is my application that is causing this card to fail because it has a very difficult time recognizing the card even in the Wii data options.
^They quit releasing new games for the GC, but they’re still producing the GameCube system as well as all first-party games released for it. Also, Nintendo hasn’t released ANY official information saying they discontinued production of the GC. The production info in the Game Daily interview is completely false, it was confirmed that Perrin Kaplan is wrong again. And so, the GC is still in production, shipped to stores, and sold worldwide and that’s a fact.

After a new round of research and testing, we found that the Unitek USB-C Card Reader is the best USB-C SD card reader for most people. Our previous pick, the Iogear USB-C 3-Slot Card Reader, is now our runner-up. We have a new, less-expensive UHS-II SD reader recommendation, the Verbatim USB-C Pocket Card Reader, and our budget and USB-A picks remain the same.
Most flash ICs come in ball grid array (BGA) packages, and even the ones that do not are often mounted on a PCB next to other BGA packages. After PCB Assembly, boards with BGA packages are often X-rayed to see if the balls are making proper connections to the proper pad, or if the BGA needs rework. These X-rays can erase programmed bits in a flash chip (convert programmed “0” bits into erased “1” bits). Erased bits (“1” bits) are not affected by X-rays.[33][34]

Flash memory (both NOR and NAND types) was invented by Fujio Masuoka while working for Toshiba circa 1980.[4][5] According to Toshiba, the name “flash” was suggested by Masuoka’s colleague, Shōji Ariizumi, because the erasure process of the memory contents reminded him of the flash of a camera.[6] Masuoka and colleagues presented the invention at the IEEE 1987 International Electron Devices Meeting (IEDM) held in San Francisco.[7]

Although data structures in flash memory cannot be updated in completely general ways, this allows members to be “removed” by marking them as invalid. This technique may need to be modified for multi-level cell devices, where one memory cell holds more than one bit.
Nintendo sold 22 million GameCube units worldwide during its lifespan,[5][81] placing it slightly behind the Xbox’s 24 million,[82] and well behind the PlayStation 2’s 153 million.[83] The GameCube’s predecessor, the Nintendo 64, outperformed it as well selling nearly 33 million units.[84] The console was able to outsell the short-lived Dreamcast, however, which yielded 9.13 million unit sales.[85] In September 2009, IGN ranked the GameCube 16th in its list of best gaming consoles of all time, placing it behind all three of its sixth-generation competitors: the PlayStation 2 (3rd), the Dreamcast (8th), and the Xbox (11th).[72] As of March 31, 2003, the GameCube had sold 9.55 million units worldwide, falling short of Nintendo’s initial goal of 10 million consoles.[86]
The SD card specification defines three physical sizes. The SD and SDHC families are available in all three sizes, but the SDXC family is not available in the mini size, and the SDIO family is not available in the micro size. Smaller cards are usable in larger slots through use of a passive adapter.
Unlike our other picks, the IOGear lacks an indicator light, so you can’t see when your card is connected or a transfer is underway at a glance. We also found that the SD card slot was a bit too shallow. The IOGear reader is slightly bigger than our other USB-C picks, but it has the best warranty of its competitors, covering three years.
Compatibility with SD and CF cards: There are a wide variety of memory card formats, but the most prominent are Secure Digital (SD), microSD, and CompactFlash (CF). We looked for readers that support SD and CF cards to ensure compatibility with as many cameras as possible; although most people don’t need CF support nowadays, we considered them for professionals and people with older cameras. We also tried to find readers that support faster UHS-II speeds for SD cards,1 but couldn’t find any USB-C readers with both UHS-II support and a CF card slot.
Version 6.0, released in February 2017, added two new data rates to the standard. FD312 provides 312 MB/s while FD624 doubles that. Both are full-duplex. The physical interface and pin-layout are the same as with UHS-II, retaining backward compatibility.[33]
Allow me a tiny bit of backstory here: when I transitioned over from one mobile OS to another (from Android to WP8), I completely lost my USB audio streaming because my [then] car (a 2011 KIA Forte), only read audio from devices that allow USB Mass Storage upon device connect (Android does, WP8 doesn’t, it uses Media Transfer Protocol (MTP), unreadable in every USB enabled car *I’ve* driven). It was was dangerous streaming music via my car’s Bluetooth because that car only allows volume control via that method, I had to pick up my phone to change songs or reach over to the windshield mount and fumble with it that way. Totally unsafe, the focus should be on driving

USB flash drives are known as the floppy disks of the 21st century. You can see people walking around with them dangling from key chains, backpacks, and even around their necks. These are more resistant to physical abuse than the media cards used in digital cameras.
Specified in SD version 3.01,[30] supports a clock frequency of 100 MHz (a quadrupling of the original “Default Speed”), which in four-bit transfer mode could transfer 50 MB/s (SDR50). UHS-I cards declared as UHS104 (SDR104) also support a clock frequency of 208 MHz, which could transfer 104 MB/s. Double data rate operation at 50 MHz (DDR50) is also specified in Version 3.01, and is mandatory for microSDHC and microSDXC cards labeled as UHS-I. In this mode, four bits are transferred when the clock signal rises and another four bits when it falls, transferring an entire byte on each full clock cycle, hence a 50 MB/s operation could be transferred using a 50 MHz clock.
EPROM and EEPROM cells operate similarly to flash memory in how data is written, or programmed, but differ from flash memory in how data is erased. An EPROM is erased by removing the chip from the system and exposing the array to ultraviolet light. An EEPROM erases data electronically at the byte level, while flash memory erases data electronically at the block level.
A host device can lock an SD card using a password of up to 16 bytes, typically supplied by the user. A locked card interacts normally with the host device except that it rejects commands to read and write data. A locked card can be unlocked only by providing the same password. The host device can, after supplying the old password, specify a new password or disable locking. Without the password (typically, in the case that the user forgets the password), the host device can command the card to erase all the data on the card for future re-use (except card data under DRM), but there is no way to gain access to the existing data.
The most important advice[according to whom?] to consumers is to continue to match SD card purchases to an application’s recommended speed class. Applications that require a specific speed class usually specify this in their user manuals.
Jump up ^ Many serial flash devices implement a bulk read mode and incorporate an internal address counter, so that it is trivial to configure them to transfer their entire contents to RAM on power-up. When clocked at 50 MHz, for example, a serial flash could transfer a 64 Mbit firmware image in less than two seconds.
Most types of memory cards available have constantly powered, nonvolatile memory, particularly NAND flash. Nonvolatile memory safeguards data in the event of a power outage, software bug or other disruption, and also eliminates the need to periodically refresh data on the memory card. Because memory cards use solid-state media, they involve no moving parts and are less likely to suffer mechanical difficulties.
In hindsight, the heating issues were probably a major warning sign. After 6 months, I plugged in my reader – and it died. Rather, it didn’t respond at all – no lights or anything, even with a SD card inside! I tested it on multiple computers and operating systems to eliminate the possibility of computer issues or driver problems – no issues. (On Linux, I checked to see if the kernel even saw it – nothing showed up at all, not even a USB error! It’s as if I plugged nothing in…)
NAND flash has reduced erase and write times, and requires less chip area per cell, thus allowing greater storage density and lower cost per bit than NOR flash; it also has up to 10 times the endurance of NOR flash. However, the I/O interface of NAND flash does not provide a random-access external address bus. Rather, data must be read on a block-wise basis, with typical block sizes of hundreds to thousands of bits. This makes NAND flash unsuitable as a drop-in replacement for program ROM, since most microprocessors and microcontrollers require byte-level random access. In this regard, NAND flash is similar to other secondary data storage devices, such as hard disks and optical media, and is thus highly suitable for use in mass-storage devices, such as memory cards. The first NAND-based removable media format was SmartMedia in 1995, and many others have followed, including:
Jump up ^ A. H. Johnston, “Space Radiation Effects in Advanced Flash Memories” Archived 4 March 2016 at the Wayback Machine.. NASA Electronic Parts and Packaging Program (NEPP). 2001. “… internal transistors used for the charge pump and erase/write control have much thicker oxides because of the requirement for high voltage. This causes flash devices to be considerably more sensitive to total dose damage compared to other ULSI technologies. It also implies that write and erase functions will be the first parameters to fail from total dose. … Flash memories will work at much higher radiation levels in the read mode. … The charge pumps that are required to generate the high voltage for erasing and writing are usually the most sensitive circuit functions, usually failing below 10 krad(SI).”

The GameCube[b] is a home video game console released by Nintendo in Japan and North America in 2001 and Europe and Australia in 2002. The sixth generation console is the successor to the Nintendo 64 and competed with Sony Computer Entertainment’s PlayStation 2 and Microsoft’s Xbox.
The standard was introduced in August 1999 by joint efforts between SanDisk, Panasonic (Matsushita Electric) and Toshiba as an improvement over MultiMediaCards (MMC),[1] and has become the industry standard. The three companies formed SD-3C, LLC, a company that licenses and enforces intellectual property rights associated with SD memory cards and SD host and ancillary products.[2]

If your smartphone, tablet or entry-level point-and-shoot camera has a memory card slot, you may opt to add a memory card to store your photos, videos, and other data like apps or music. In these cases, you will be more concerned about the card’s storage capacity than its speed. Though they are small, microSD cards can offer large capacities of 128GB and more. Whichever size card you’re interested in, you’ll want to make sure before you buy that your device will support that capacity.
Since 2010, new products of Sony (previously only using Memory Stick) and Olympus (previously only using XD-Card) have been offered with an additional SD-Card slot.[1] Effectively the format war has turned in SD-Card’s favor.[2][3][4]
This reader does exactly what it says – it can read and write regular SD cards and MicroSD cards. The speeds aren’t amazing, but it will get the job done. It takes around a minute or more to transfer a 1 GB file, versus a USB 3.0 reader (on USB 2.0) taking around 30 seconds or less. The USB 3.0 reader I’m using now is this: Transcend Information USB 3.0 Card Reader (TS-RDF5K)
An additional subcategory is a hybrid hard drive that combines a conventional HDD with a NAND flash module. A hybrid hard drive is generally viewed as a way to bridge the divide between rotating media and flash memory.
It gets two stars because it can save/load so it does work…but my Wii has a very difficult time recognizing the card and I have to pull it out of the slot and insert it back several times for it to read. For how often I am going to use it this is okay. It is frustrating and not what I want to do but it will work.
For example, if your host device requires a Speed Class 4 SD memory card, you can use Speed Class 4, 6 or 10 SD memory cards. If your host device requires a UHS Speed Class 1 SD memory card, you can use UHS Speed Class 1 or 3 SD memory cards. Video Speed Class is also the same. Note that expected write speed will not be available by a combination of different class symbols such as Class 10, U1 and V10 even those are indicated to the same 10MB/sec write speed.
In 2008, the SDA specified Embedded SD, “leverag[ing] well-known SD standards” to enable non-removable SD-style devices on printed circuit boards.[98] However this standard was not adopted by the market while the MMC standard became the de facto standard for embedded systems. SanDisk provides such embedded memory components under the iNAND brand.[99]

The SanDisk Extreme Pro UHS-II Card USB-C Reader was our previous recommendation for UHS-II speeds, but it costs nearly three times as much as the Verbatim, and it doesn’t have a microSD slot. Its SD card read and write speeds were about 39 MB/s and 31 MB/s faster than the Verbatim’s, though, and it has a useful indicator light and a simple design.
Integrated USB connector – The SanDisk SD Plus product can be plugged directly into a USB port without needing a USB card reader.[55] Other companies introduced comparable products, such as the Duo SD product of OCZ Technology and the 3 Way (microSDHC, SDHC, and USB) product of A-DATA, which was available in 2008 only.

However, when I look at “This PC” (I am on Windows 10) via File Explorer, I still cannot see anything that looks like an SD drive listed…. I’m back to square one.

The Kingston had read and write speeds of 186 MB/s and 172 MB/s, respectively, during our SD card test—it’s slower than Verbatim’s USB-C reader, but it had the most consistent performance of the USB-A readers we tested. In our microSD card test, the Kingston had expected read and write speeds of 90 MB/s and 68 MB/s. It was a little slower than our other picks when reading and writing to a CF card, with speeds of 144 MB/s and 136 MB/s, respectively.
The specific commands used to lock, unlock, program, or erase NOR memories differ for each manufacturer. To avoid needing unique driver software for every device made, special Common Flash Memory Interface (CFI) commands allow the device to identify itself and its critical operating parameters.
A hybrid flash array blends disk and SSDs. Hybrid arrays use SSDs as a cache to speed access to frequently requested hot data, which subsequently is rewritten to back-end disk. Many enterprises commonly archive data from disk as it ages by replicating it to an external magnetic tape library.
Many ASICs are pad-limited, meaning that the size of the die is constrained by the number of wire bond pads, rather than the complexity and number of gates used for the device logic. Eliminating bond pads thus permits a more compact integrated circuit, on a smaller die; this increases the number of dies that may be fabricated on a wafer, and thus reduces the cost per die.

When dealing with larger, high-resolution files, you may think that capacity is your first concern. However, the speed of a memory card plays a huge part when filming 4K video, taking large print-quality photos, and taking rapid burst shots. This type of photography may require a higher write or read speed in order to process data quickly. When looking at memory cards, it’s important to delineate write speed and read speed and make sure you get what works best for each.
There are 2 options I am aware of: use the Win 10 option to back out the upgrade and go back to the last OS, or buy a new external card reader that plugs into a USB port [and live without the built-in card slot]. The Insignia NS-DCR30A2 USB 3.0 Multiformat Memory Card Reader I bought at Best Buy also works with USB 2 and reads my cards up to and including the 64GB SDXC. (An older external reader I had would not handle the 32 and 64GB cards.)

Because of the series connection and removal of wordline contacts, a large grid of NAND flash memory cells will occupy perhaps only 60% of the area of equivalent NOR cells[50] (assuming the same CMOS process resolution, for example, 130 nm, 90 nm, or 65 nm). NAND flash’s designers realized that the area of a NAND chip, and thus the cost, could be further reduced by removing the external address and data bus circuitry. Instead, external devices could communicate with NAND flash via sequential-accessed command and data registers, which would internally retrieve and output the necessary data. This design choice made random-access of NAND flash memory impossible, but the goal of NAND flash was to replace mechanical hard disks, not to replace ROMs.
In 1997, a graphics hardware design company called ArtX was launched, staffed by twenty engineers who had previously worked at SGI on the design of the Nintendo 64’s graphics hardware. The team was led by Dr. Wei Yen, who had been SGI’s head of Nintendo Operations, the department responsible for the Nintendo 64’s fundamental architectural design.[7][8]
It takes up the most space of all our picks, measuring 3.5 by 2 by 0.6 inches, and it weighs 4 ounces. The Kingston card reader isn’t terrible to look at, despite the loud red-and-white design on its top (including a large, red “Kingston” logo that doubles as an indicator light), but it isn’t as attractive as other readers we tested. It comes bundled with a removable, 43-inch connecting cable. None of the other readers we tested had a cable that was this long, or removable.
With the GameCube, Nintendo failed to reclaim the market share lost by its predecessor, the Nintendo 64. Throughout the lifespan of its console generation, GameCube hardware sales remained far behind its direct competitor the PlayStation 2, and slightly behind Microsoft’s Xbox. The console’s “family-friendly” appeal and lack of support from certain third-party developers skewed the GameCube toward a younger market, which was a minority demographic of the gaming population during the sixth generation.[96] Many third-party games popular with teenagers or adults, such as the blockbuster Grand Theft Auto series and several key first-person shooters, skipped the GameCube entirely in favor of the PlayStation 2 and Xbox.
Flash memory offers non-volatile data storage and thus is capable of retaining it’s data even when it’s power source has been turned off. This makes it ideal for devices such as digital cameras where batteries go dead often. With being able to retain data even when power is lost you can rest assured that all your pictures will still be kept safe on the memory card. Examples of flash memory cards include Secure Digital (SD) memory cards, Compact Flash (CF) memory cards, and Sony’s Memory Sticks (MS, M2, MS Duo, MS Pro, and MS Pro Duo) to name a few. Other examples of proprietary and permanent flash memory devices include memory cards for video gaming systems.
Cards that comply with UHS show Roman numerals ‘I’, ‘II’ or ‘III’ next to the SD card logo,[27][34] and report this capability to the host device. Use of UHS-I requires that the host device command the card to drop from 3.3-volt to 1.8-volt operation over the I/O interface pins and select the four-bit transfer mode, while UHS-II requires 0.4-volt operation.
A joint development at Intel and Micron will allow the production of 32-layer 3.5 terabyte (TB) NAND flash sticks and 10 TB standard-sized SSDs. The device includes 5 packages of 16 × 48 GB TLC dies, using a floating gate cell design.[66]
SDIO cards support most of the memory commands of SD cards. SDIO cards can be structured as eight logical cards, although currently, the typical way that an SDIO card uses this capability is to structure itself as one I/O card and one memory card.
Flash memory was first introduced in 1980 and developed by Dr. Fujio Masuoka, an inventor and mid level factory manager at Toshiba Corporation (TOSBF). Flash memory was named after its capability to erase a block of data “”in a flash.” Dr. Masuoka’s objective was to create a memory chip preserving data when the power was turned off. Dr. Masuoka also invented a type of memory known as SAMOS and developed a 1Mb dynamic random access memory (DRAM). In 1988, Intel Corporation produced the first commercial NOR-type flash chip, which replaced the permanent read-only memory (ROM) chip on PC motherboards containing the basic input/output operating system (BIOS).
Flash dual inline memory module (DIMM), otherwise known as memory channel solid-state storage, which exploits idle DIMM DRAM slots as low-latency, high-performance flash cache to buffer host server performance.

USB 3.0 speeds: We considered only USB 3.0 (or faster) card readers in this review, because outdated USB 2.0 card readers aren’t fast enough. Theoretically, USB 2.0 readers can deliver speeds up to 60 MB/s, but they regularly max out at 20 MB/s. With a USB 3.0 card reader, you should be able to enjoy the full speed of a UHS-I SD card. We made our picks based on their ability to deliver fast speeds for each card.
Version 6.0, released in February 2017, added two new data rates to the standard. FD312 provides 312 MB/s while FD624 doubles that. Both are full-duplex. The physical interface and pin-layout are the same as with UHS-II, retaining backward compatibility.[33]

While EPROMs had to be completely erased before being rewritten, NAND-type flash memory may be written and read in blocks (or pages) which are generally much smaller than the entire device. NOR-type flash allows a single machine word (byte) to be written – to an erased location – or read independently.
When an SD is inserted, the driver appears in the device manager and a drive letter is assigned. An update request indicates the driver is up-to-date. Uninstalling and reinstalling the driver does not help. There were popups asking to reformat the card, but don’t do it because the card is not the problem. Win 7 read all my cards just fine, and Win 10 does not.
A group called the Open NAND Flash Interface Working Group (ONFI) has developed a standardized low-level interface for NAND flash chips. This allows interoperability between conforming NAND devices from different vendors. The ONFI specification version 1.0[44] was released on 28 December 2006. It specifies:
Despite the additional transistors, the reduction in ground wires and bit lines allows a denser layout and greater storage capacity per chip. (The ground wires and bit lines are actually much wider than the lines in the diagrams.) In addition, NAND flash is typically permitted to contain a certain number of faults (NOR flash, as is used for a BIOS ROM, is expected to be fault-free). Manufacturers try to maximize the amount of usable storage by shrinking the size of the transistors.

The NAND type operates primarily in memory cards, USB flash drives, solid-state drives (those produced in 2009 or later), and similar products, for general storage and transfer of data. NAND or NOR flash memory is also often used to store configuration data in numerous digital products, a task previously made possible by EEPROM or battery-powered static RAM. One key disadvantage of flash memory is that it can only endure a relatively small number of write cycles in a specific block.[1]
As of 2013, V-NAND flash architecture allows read and write operations twice as fast as conventional NAND and can last up to 10 times as long, while consuming 50 percent less power. They offer comparable physical bit density using 10-nm lithography, but may be able to increase bit density by up to two orders of magnitude.[24]

In flash memory, each memory cell resembles a standard MOSFET, except that the transistor has two gates instead of one. On top is the control gate (CG), as in other MOS transistors, but below this there is a floating gate (FG) insulated all around by an oxide layer. The FG is interposed between the CG and the MOSFET channel. Because the FG is electrically isolated by its insulating layer, electrons placed on it are trapped until they are removed by another application of electric field (e.g. Applied voltage or UV as in EPROM). Counter-intuitively, placing electrons on the FG sets the transistor to the logical “0” state. Once the FG is charged, the electrons in it screen (partially cancel) the electric field from the CG, thus, increasing the threshold voltage (VT1) of the cell. This means that now a higher voltage (VT2) must be applied to the CG to make the channel conductive. In order to read a value from the transistor, an intermediate voltage between the threshold voltages (VT1 & VT2) is applied to the CG. If the channel conducts at this intermediate voltage, the FG must be uncharged (if it was charged, we would not get conduction because the intermediate voltage is less than VT2), and hence, a logical “1” is stored in the gate. If the channel does not conduct at the intermediate voltage, it indicates that the FG is charged, and hence, a logical “0” is stored in the gate. The presence of a logical “0” or “1” is sensed by determining whether there is current flowing through the transistor when the intermediate voltage is asserted on the CG. In a multi-level cell device, which stores more than one bit per cell, the amount of current flow is sensed (rather than simply its presence or absence), in order to determine more precisely the level of charge on the FG.

You’ll need a memory card reader to transfer photos to your computer if you don’t fancy lugging around a USB cable for every one of your devices. You’ll be able to get a card reader for each of the above types of memory cards and some come with built in memory and can also function as a USB flash drive. But check the device you’re loading your photos to as some computers, printers and notebooks already come with built-in memory card slots. If you’re using more than one memory card regularly it will probably be worth investing in a multi-card reader, which accept multiple types of memory cards and brands. Some even take as many as 35-in-1.
Flash memory devices are typically much faster at reading than writing.[69] Performance also depends on the quality of storage controllers which become more critical when devices are partially full.[69] Even when the only change to manufacturing is die-shrink, the absence of an appropriate controller can result in degraded speeds.[70]
The main disadvantages of flash memory are the wear-out mechanism and cell-to-cell interference as the dies get smaller. Bits can fail with excessively high numbers of program/erase cycles, which eventually break down the oxide layer that traps electrons. The deterioration can distort the manufacturer-set threshold value at which a charge is determined to be a zero or a one. Electrons may escape and get stuck in the oxide insulation layer, leading to errors and bit rot.
The method used to read NAND flash memory can cause nearby cells in the same memory block to change over time (become programmed). This is known as read disturb. The threshold number of reads is generally in the hundreds of thousands of reads between intervening erase operations. If reading continually from one cell, that cell will not fail but rather one of the surrounding cells on a subsequent read. To avoid the read disturb problem the flash controller will typically count the total number of reads to a block since the last erase. When the count exceeds a target limit, the affected block is copied over to a new block, erased, then released to the block pool. The original block is as good as new after the erase. If the flash controller does not intervene in time, however, a read disturb error will occur with possible data loss if the errors are too numerous to correct with an error-correcting code.[30][31][32]

If you use a camera or cards that support UHS-II speeds, we recommend the Verbatim USB-C Pocket Card Reader. The Verbatim had read and write speeds of 227 MB/s and 219 MB/s, respectively—around 2.5 times the speed of our top pick—but it cannot read multiple cards at once. It also lacks a CF card slot (so high-end DSLR owners may want to look at our pick for traditional USB ports, along with an adapter if they need USB-C compatibility) and an indicator light, but it costs around the same price as our top pick and comes with a one-year warranty.

2) I put it in the camera, and the Nikon D40 immediately formatted the card and it was ready for use. The information screen said that it was ready to hold 2.2K (2200) pictures. I held down the shutter in continuous mode, and fired off about 20 seconds of pictures (the D40 shoots somewhere around 3 or 3.3 pics per second in burst mode). There was no stutter, lag, etc. when writing to the card. This SDHC card (remember different format than SD, which was the format available when I bought the camera) worked flawlessly in this little test. I buy only SanDisk or Lexar products, and I can say that media from neither company has ever let me down. The two Lexar cards have stored downloaded and erased around 72K pictures over six years, generally at 300-500 pics per download/erase/format cycle and are still going strong with the original capacity intact.
xD cards are simply 18-pin NAND flash chips in a special package and support the standard command set for raw NAND flash access. Although the raw hardware interface to xD cards is well understood, the layout of its memory contents—necessary for interoperability with xD card readers and digital cameras—is totally undocumented. The consortium that licenses xD cards has not released any technical information to the public.
The Kingston had read and write speeds of 186 MB/s and 172 MB/s, respectively, during our SD card test—it’s slower than Verbatim’s USB-C reader, but it had the most consistent performance of the USB-A readers we tested. In our microSD card test, the Kingston had expected read and write speeds of 90 MB/s and 68 MB/s. It was a little slower than our other picks when reading and writing to a CF card, with speeds of 144 MB/s and 136 MB/s, respectively.
With the GameCube, Nintendo aimed to reverse the trend as evidenced by the number of third-party games available at launch – the N64 had none. The new optical disc format introduced with the GameCube increased the capacity significantly and reduced production costs. For the most part, the strategy worked. High-profile exclusives such as Star Wars Rogue Squadron II: Rogue Leader from Factor 5, Resident Evil 4 from Capcom, and Metal Gear Solid: The Twin Snakes from Konami were very successful. Sega, which focused on third-party development following the demise of its Dreamcast console, offered a vast amount of support for the GameCube porting old favorites over such as Crazy Taxi and Sonic Adventure 2. The company also started new franchises on the GameCube including Super Monkey Ball. Several third-party developers were contracted to work on new games for existing Nintendo franchises, including Star Fox Assault by Namco and Wario World from Treasure.[59][61]
The reverse happens when using Fowler-Nordheim tunneling to trap electrons in the floating gate. Electrons manage to forge through the thin oxide layer to the floating gate in the presence of a high electric field, with a strong negative charge on the cell’s source and the drain and a strong positive charge on the control gate.
Secure Digital cards are used in many consumer electronic devices, and have become a widespread means of storing several gigabytes of data in a small size.[citation needed] Devices in which the user may remove and replace cards often, such as digital cameras, camcorders, and video game consoles, tend to use full-sized cards.[citation needed] Devices in which small size is paramount, such as mobile phones, tend to use microSD cards.[citation needed]
Speed classes 2, 4, and 6 assert that the card supports the respective number of megabytes per second as a minimum sustained write speed for a card in a fragmented state. Class 10 asserts that the card supports 10 MB/s as a minimum non-fragmented sequential write speed and uses a High Speed bus mode.[30] The host device can read a card’s speed class and warn the user if the card reports a speed class that falls below an application’s minimum need.[30] By comparison, the older “×” rating measured maximum speed under ideal conditions, and was vague as to whether this was read speed or write speed. The graphical symbol for the speed class has a number encircled with ‘C’ (C2, C4, C6, and C10).
In most respects, the above types of flash memory cards differ from those used in enterprise storage. EMC is credited with being the first vendor to include SSDs in enterprise storage hardware when it added them to its Symmetrix disk arrays in 2008, spawning the advent of hybrid arrays that combine flash drives with a traditional spinning disk. Initially, enterprise SSDs in hybrid arrays were relegated for caching read data in flash due to their higher cost and lower endurance compared to HDDs.

The first thing to consider when getting a memory card is where you’re going to use it. Different cameras, camcorders, and smartphones use different sizes of card, and while you can start with the smallest and use adapters to work your way up, it’s generally best to use the card size intended for the device.
The next step is to form a cylindrical hole through these layers. In practice, a 128 Gibit V-NAND chip with 24 layers of memory cells requires about 2.9 billion such holes. Next the hole’s inner surface receives multiple coatings, first silicon dioxide, then silicon nitride, then a second layer of silicon dioxide. Finally, the hole is filled with conducting (doped) polysilicon.[24]
The Cable Matters reader has similar speeds to the Unitek and Iogear readers. During our SD card tests, the Cable Matters reader had a read speed of 92 MB/s and a write speed of 86 MB/s. When we tested the unit with a microSD card, it had a read and write speed of 92 MB/s and 71 MB/s, respectively. The Cable Matters can also read two cards simultaneously, like our top pick, though its speeds drop sharply. Running an SD and a microSD card at the same time gave us abysmal read and write speeds of 19.5 MB/s and 17.2 MB/s from both cards, respectively. The Unitek gave us decent read and write speeds of 59 MB/s and 49 MB/s when transferring data from two cards at once.
NAND flash architecture was introduced by Toshiba in 1989.[38] These memories are accessed much like block devices, such as hard disks. Each block consists of a number of pages. The pages are typically 512[39] or 2,048 or 4,096 bytes in size. Associated with each page are a few bytes (typically 1/32 of the data size) that can be used for storage of an error correcting code (ECC) checksum.
Nintendo began its marketing campaign with the catchphrase “The Nintendo Difference” at its E3 2001 reveal.[16] The goal was to distinguish itself from the competition as an entertainment company.[23] Later advertisements push the slogan, “Born to Play”, and video game commercials feature a rotating cube animation that morphs into a GameCube logo and ends with a voice whispering, “GameCube”.[24][25] On May 21, 2001, the console’s launch price of $199 was announced- $100 lower than that of Sony’s PlayStation 2 and Microsoft’s Xbox.[26]
If you use only SD and microSD cards, you should get the Cable Matters USB 3.1 Type-C Dual Slot Card Reader. The Cable Matters reader has similar speeds to the IOGear and Transcend readers, but it doesn’t support CF cards. It’s smaller, lighter, and cheaper than our other top picks, plus it has good speeds and an indicator light. It also comes with only a one-year warranty.
UHS memory cards work best with UHS host devices. The combination lets the user record HD resolution videos with tapeless camcorders while performing other functions. It is also suitable for real-time broadcasts and capturing large HD videos.
The SD protocol envisioned the ability to gang 30 cards together without separate chip select lines. The host device would broadcast commands to all cards and identify the card to respond to the command using its unique serial number.[citation needed]
It is the smallest memory card that can be bought; at 15 mm × 11 mm × 1 mm (about the size of a fingernail), it is about a quarter of the size of a normal-sized SD card.[2] There are adapters that make the small microSD able to fit in devices that have slots for standard SD, miniSD, Memory Stick Duo card, and even USB. But, not all of the different cards can work together. Many microSD cards are sold with a standard SD adapter, so that people can use them in devices that take standard SD but not microSD cards.

It gets two stars because it can save/load so it does work…but my Wii has a very difficult time recognizing the card and I have to pull it out of the slot and insert it back several times for it to read. For how often I am going to use it this is okay. It is frustrating and not what I want to do but it will work.

Integrated Wi-Fi – Several companies produce SD cards with built-in Wi-Fi transceivers supporting static security (WEP 40; 104; and 128, WPA-PSK, and WPA2-PSK). The card lets any digital camera with an SD slot transmit captured images over a wireless network, or store the images on the card’s memory until it is in range of a wireless network. Examples include: Eye-Fi / SanDisk, Transcend Wi-Fi, Toshiba FlashAir, Trek Flucard, PQI Air Card and LZeal ez Share.[52] Some models geotag their pictures.
Write amplification: The flash controller may need to overwrite more data than requested. This has to do with performing read-modify-write operations on write blocks, freeing up (the much larger) erase blocks, while moving data around to achieve wear leveling.
Flash memory offers non-volatile data storage and thus is capable of retaining it’s data even when it’s power source has been turned off. This makes it ideal for devices such as digital cameras where batteries go dead often. With being able to retain data even when power is lost you can rest assured that all your pictures will still be kept safe on the memory card. Examples of flash memory cards include Secure Digital (SD) memory cards, Compact Flash (CF) memory cards, and Sony’s Memory Sticks (MS, M2, MS Duo, MS Pro, and MS Pro Duo) to name a few. Other examples of proprietary and permanent flash memory devices include memory cards for video gaming systems.
Compared to NOR flash, replacing single transistors with serial-linked groups adds an extra level of addressing. Whereas NOR flash might address memory by page then word, NAND flash might address it by page, word and bit. Bit-level addressing suits bit-serial applications (such as hard disk emulation), which access only one bit at a time. Execute-in-place applications, on the other hand, require every bit in a word to be accessed simultaneously. This requires word-level addressing. In any case, both bit and word addressing modes are possible with either NOR or NAND flash.
In 2002, Nintendo introduced the WaveBird Wireless Controller, the first wireless gamepad developed by a first-party console manufacturer. The RF-based wireless controller is similar in design to the standard controller. It communicates with the GameCube by way of a wireless receiver dongle connected to one of the console’s controller ports. Powered by two AA batteries, which are housed in a compartment on the underside of the controller, the WaveBird lacks the vibration functionality of the standard controller. In addition to the standard inputs, the WaveBird features a channel selection dial – also found on the receiver – and an on/off switch. An orange LED on the face of the controller indicates when it is powered on. The controller is available in light grey and platinum color schemes.[55]

Like its predecessor, the Nintendo 64, GameCube models were produced in several different color motifs. The system launched in “Indigo”, the primary color shown in advertising and on the logo, and in “Jet Black”.[40] A year later, Nintendo released a “Platinum” limited edition GameCube, which uses a silver color scheme for both the console and controller.[41] A “Spice” orange-colored console was eventually released as well only in Japan, though the color scheme could be found on controllers released in other countries.[42]
While larger is better, you need to make sure your device can use the larger card. The SD/SDHC/SDXC classification isn’t just for cards, but for devices as well. Older digital cameras can only read SD cards, making SDHC cards useless. Similarly, cameras that aren’t SDXC-compatible won’t accept 64GB cards. Most current devices are SDHC compatible, but double-check your older devices before getting SDHC cards, and check the specs on your newer gear before getting SDXC cards.
Home consoles now commonly use hard disk drive storage for saved games and allow the use of generic USB flash drives or other card formats via a memory card reader to transport game saves and other game information, along with cloud storage saving, though most portable gaming systems still rely on custom memory cartridges to store program data, due to their low power consumption, smaller physical size and reduced mechanical complexity.

In 2008, the SDA specified Embedded SD, “leverag[ing] well-known SD standards” to enable non-removable SD-style devices on printed circuit boards.[98] However this standard was not adopted by the market while the MMC standard became the de facto standard for embedded systems. SanDisk provides such embedded memory components under the iNAND brand.[99]
In most cases, once the Micro SD Card is inserted in your phone, your phone automatically starts scanning the card, pulls out all the information MicroSD Card  needs, and immediately stores information in the appropriate location. So that Micro SD Card will start working directly.
Today’s digital cameras take increasingly high quality photos, so there is a greater need for storage space to store these high-resolution files. The SanDisk Standard memory cards come in capacities of up to 32 GB1, allowing you to take plenty of photos without running out of space. With the Standard SD memory card, you won’t miss those special moments like a baby’s first steps, a child’s first dance recital, or a treasured vacation moment.

The presence of a notch, and the presence and position of a tab, have no effect on the SD card’s operation. A host device that supports write protection should refuse to write to an SD card that is designated read-only in this way. Some host devices do not support write protection, which is an optional feature of the SD specification. Drivers and devices that do obey a read-only indication may give the user a way to override it.

Contemporary reception of the GameCube was generally positive. The console was praised for its controller, extensive software library and high-quality games, but was criticized for its exterior design and lack of features. Nintendo sold 21.74 million GameCube units worldwide before it was discontinued in 2007. Its successor, the Wii, which has backward compatibility with most GameCube software, was released in November 2006.
Although many personal computers accommodate SD cards as an auxiliary storage device using a built-in slot, or can accommodate SD cards by means of a USB adapter, SD cards cannot be used as the primary hard disk through the onboard ATA controller, because none of the SD card variants support ATA signalling. Primary hard disk use requires a separate SD controller chip[96] or an SD-to-CompactFlash converter. However, on computers that support bootstrapping from a USB interface, an SD card in a USB adapter can be the primary hard disk, provided it contains an operating system that supports USB access once the bootstrap is complete.

The Kingston had read and write speeds of 159 MB/s and 127 MB/s, respectively, during our SD card test. In our microSD card test, it had expected read and write speeds of 83 MB/s and 69 MB/s. It was a bit slower when reading and writing to a CF card, with speeds of 127 MB/s and 107 MB/s.
Jump up ^ Many serial flash devices implement a bulk read mode and incorporate an internal address counter, so that it is trivial to configure them to transfer their entire contents to RAM on power-up. When clocked at 50 MHz, for example, a serial flash could transfer a 64 Mbit firmware image in less than two seconds.
SD card: Postage stamp-sized device widely used in a variety of handheld devices, including digital cameras, smartphones and tablets. SD cards secure digital data by encrypting it on the device. SanDisk offers the highest capacity SD card at 512 gigabytes (GB).
Channel hot-electron injection, also known as hot-carrier injection, enables electrons to break through the gate oxide and change the threshold voltage of the floating gate. This breakthrough occurs when electrons acquire a sufficient amount of energy from the high current in the channel and the attracting charge on the control gate.

Overall, SD is less open than CompactFlash or USB flash memory drives. Those open standards can be implemented without paying for licensing, royalties, or documentation. (CompactFlash and USB flash drives may require licensing fees for the use of the SDA’s trademarked logos.)
Read speed determines how fast data can be retrieved from the card. A faster read speed means you can more quickly transfer data from the card onto a computer or printer. Faster read speeds decrease your wait time so you can edit, save and share faster. For example, if you were shooting weddings, or doing work where you’d have to download a large amount of large raw image files to the computer, you’d want a higher read speed. However, read speed is really more of a convenience, whereas your primary focus should be write speed when you’re looking for a memory card.
MultiMediaCard: Developed in 1997 by SanDisk and Siemens, MMCs were originally designed to use NAND flash memory technology from Toshiba. However, MMCs are less common with the arrival of SD card technology. Most computer hardware vendors no longer provide ports for inserting an MMC device. A new development is embedded MMC, or eMMC, in which the flash card is integrated on the computer motherboard along with controller software to use the eMMC as a bootable system drive. MMCs weigh approximately two grams.

But, not all of the different cards can work together. Many microSD cards are sold with a standard SD adapter, so that people can use them in devices that take standard SD but not microSD cards.

Example applications of both types of flash memory include personal computers, PDAs, digital audio players, digital cameras, mobile phones, synthesizers, video games, scientific instrumentation, industrial robotics, and medical electronics. In addition to being non-volatile, flash memory offers fast read access times, although not as fast as static RAM or ROM.[2] Its mechanical shock resistance helps explain its popularity over hard disks in portable devices, as does its high durability, ability to withstand high pressure, temperature and immersion in water, etc.[3]

SD cards are not the most economical solution in devices that need only a small amount of non-volatile memory, such as station presets in small radios. They may also not present the best choice for applications that require higher storage capacities or speeds as provided by other flash card standards such as CompactFlash. These limitations may be addressed by evolving memory technologies, such as the world’s highest capacity SanDisk Ultra 200GB microSD released in 2015.[89]

The command interface is an extension of the MultiMediaCard (MMC) interface. SD cards dropped support for some of the commands in the MMC protocol, but added commands related to copy protection. By using only commands supported by both standards until determining the type of card inserted, a host device can accommodate both SD and MMC cards.
Flash memory is a type of electronically erasable programmable read only memory (EEPROM), but may also be a standalone memory storage device such as a USB drive. EEPROM is a type of data memory device using an electronic device to erase or write digital data. Flash memory is a distinct type of EEPROM, which is programmed and erased in large blocks.

Micro SD Card Reader drivers are tiny programs that enable your Micro SD Card Reader hardware to communicate with your operating system software. Maintaining updated Micro SD Card Reader software prevents crashes and maximizes hardware and system performance. Using outdated or corrupt Micro SD Card Reader drivers can cause system errors, crashes, and cause your computer or hardware to fail. Furthermore, installing the wrong Micro SD Card Reader drivers can make these problems even worse.
The latest format for top-end cameras and camcorders is XQD. Even faster than CFast, it has the fastest write speed of all. Found in select top-end cameras, XQD is PCIe based, and doesn’t have the same speed limitations as CFast or CompactFlash. Often a top-end camera will use either CFast or XQD, but not both.

Doubling the storage space of the 16GB variety, the Sandisk Extreme Pro 32GB features the same high-speed spec, but with even more space. Perfect for the avid videographer shooting lots of high quality videos, at a great price.

I am using this memory card for saving Gamecube games on my softmodded Wii. I am USB loading the games with Dios-Mios. That being said, I doubt that it is my application that is causing this card to fail because it has a very difficult time recognizing the card even in the Wii data options.

MiniSD cards, the least frequently used format these days, measure 21.5 by 20 by 1.4 mm (HWD) and weigh just a gram, making them just over a third the volume and taking up just over half the area of a full-size SD card. Instead of cut corners, miniSD cards have a tapered corner to help you orient the card when putting it in a slot. This design aspect follows with the smallest of the SD cards, the microSD card.
After researching all the USB-C SD readers available, we called in 12 models that met our requirements by accessories makers we trust. Then we plugged them into a 2016 MacBook Pro and a 2016 Dell XPS 13 and used AJA System Test and CrystalDiskMark to test their speeds with three SanDisk cards–one SD card, one microSD card, and one CF card.

Consumer-grade solid-state drives (SSDs) embed silicon-based memory chips as storage media for persistent storage of data. The earliest SSDs were generally designed for consumer devices. The debut of the Apple iPod in 2005 marked the first notable flash-based device to broadly penetrate the consumer market. SanDisk has a line of portable SSDs that scale to 1.92 terabytes (TB) of flash capacity; they are marketed mainly for flash storage of digital photography.
The SD Standard allows usage of only the above-mentioned Microsoft FAT file systems and any card produced in the market shall be preloaded with the related standard file system upon its delivery to the market. If any application or user re-formats the card with a non-standard file system the proper operation of the card, including interoperability, cannot be assured.
The low-level interface to flash memory chips differs from those of other memory types such as DRAM, ROM, and EEPROM, which support bit-alterability (both zero to one and one to zero) and random access via externally accessible address buses.
