note 5 memory card | best micro sd card for phones

These devices include the Secure Digital card (SD card) and its smaller variant, the microSD card; Secure Digital High Capacity (SDHC) card; CompactFlash card (CF card); SmartMedia card; Memory Stick; MultiMediaCard (MMC); xD-Picture card; and USB card.
TransFlash cards are sold in 16MB and 32MB sizes. microSD cards are sold in many sizes, from 64 MB to 32 GB, while microSDHC cards are sold in sizes between 4 GB to 64 GB. Larger ones are microSDXC memory cards, sold in sizes between 8 GB and 256 GB. [5]
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.
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.
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]
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.

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.
The Unitek USB-C Card Reader is the best SD card reader for most people because it produced reliably fast speeds during our SD, microSD, and CF tests, and it has a pocketable design (with a useful indicator light) that’s easy to use. It’s also affordable at around $20, and comes with a two-year warranty.
My experience with this 64MB Memory Card is with a Wii used to play GameCube games. There are lots of good reviews but when I used the card, the GameCube did not recognize the card at all. After reading the 3/2/1 star reviews, I saw that: (1) The card seems to perform much better with an actual GameCube (2) People were able to get the card working with the Wii by wiggling it around (not really a good sign) (3) People have had corruption issues with the card – usually with the Wii. After searching around, I found that even Nintendo larger capacity cards have this problem with the Wii. The recommendation is to use the low capacity Nintendo cards which are priced fairly low. After all of that, I tried this 64MB card again and it is working – which is why I am giving 3 stars. I also ordered the Nintendo lower capacity card and will switch over to it when it arrives (for reliability).
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).
A solid-state drive was offered as an option with the first MacBook Air introduced in 2008, and from 2010 onwards, all models shipped with an SSD. Starting in late 2011, as part of Intel’s Ultrabook initiative, an increasing number of ultra-thin laptops are being shipped with SSDs standard.
Also in early 2010, commercial SDXC cards appeared from Toshiba (64 GB),[69][70] Panasonic (64 GB and 48 GB),[71] and SanDisk (64 GB).[72] In early 2011, Centon Electronics, Inc. (64 GB and 128 GB) and Lexar (128 GB) began shipping SDXC cards rated at Speed Class 10.[73] Pretec offered cards from 8 GB to 128 GB rated at Speed Class 16.[74]
^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.
At the 2000 Consumer Electronics Show (CES) trade show, the three companies announced the creation of the SD Association (SDA) to promote SD cards. The SD Association, headquartered in San Ramon, California, United States, started with about 30 companies and today consists of about 1,000 product manufacturers that make interoperable memory cards and devices. Early samples of the SD Card became available in the first quarter of 2000, with production quantities of 32 and 64 MB cards available three months later.
This card arrived quickly (Fulfillment by Amazon, sold by SanDisk + Prime Membership)! I ordered two of them, because ordering individual cards was a little less expensive than ordering them in pairs or quads (go figure???).
Hewlett Packard Enterprise and SanDisk are partnering on a similar initiative to develop storage-class memory based on SanDisk’s nonvolatile resistive random-access memory (ReRAM) technology, which would be used to design a new class of SSDs.

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.
The IOGear USB-C 3-Slot Card Reader is the best SD card reader for most people because it’s affordable (usually less than $20) and produced fast speeds during our SD, microSD, and CF tests, every single time.
This card writes at a C4 speed (as indicated by the number 4 encircled by a C on the label). It’s a decent speed for smaller files, but considering a RAW photo files can be rather large, if you’re shooting high res, RAW files, this is not the card for you. It will absolutely freeze up your camera.

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.
A flash memory card (sometimes called a storage card) is a small storage device that uses nonvolatile semiconductor memory to store data on portable or remote computing devices. Such data includes text, pictures, audio and video. Most current products use flash memory, although other memory technologies are being developed, including devices that combine dynamic random access memory (DRAM) with flash memory.
The earliest commercially designed SSDs were made with single-level cell (SLC) or multi-level cell (MLC) flash. SLC uses a high grade of flash media to provide performance and endurance, but it typically costs twice as much as MLC flash.
In addition, speed may vary markedly between writing a large amount of data to a single file (sequential access, as when a digital camera records large photographs or videos) and writing a large number of small files (a random-access use common in smartphones). A study in 2012 found that, in this random-access use, some Class 2 cards achieved a write speed of 1.38 MB/s, while all cards tested of Class 6 or greater (and some of lower Classes; lower Class does not necessarily mean better small-file performance), including those from major manufacturers, were over 100 times slower.[35] In 2014, a blogger measured a 300-fold performance difference on small writes; this time, the best card in this category was a class 4 card.[36]
MicroSD cards, which are used in most cell phones and smartphones, are downright Lilliputian, measuring 15 by 11 by 1 mm (HWD) and weighing only half a gram. With a total volume of 165 mm3, you could fit nine microSD cards inside a single SD card (though realistically, with the slight lip found on the end of microSD cards, you could probably only squeeze in six).
The console was announced as the Nintendo GameCube at a press conference in Japan on August 24, 2000,[13] abbreviated as “NGC” in Japan[14] and “GCN” in North America.[15] Nintendo unveiled its software lineup for the sixth generation console at E3 2001, focusing on fifteen launch games, including Luigi’s Mansion and Star Wars Rogue Squadron II: Rogue Leader.[16] Several games originally scheduled to launch with the console were delayed.[17] It is also the first console in the company’s history not to accompany a Super Mario platform game at launch.[18]

  1. While the SD Association (the group that defines SD card technology) doesn’t release exact speed standards for card classes to non-members, it does offer loose guidelines for which classes are acceptable various uses. Class 2 is suitable for standard-definition video recording, while Class 4 and Class 6 can record high-definition video. Class 10 is the card for HD video and “HD still consecutive recording,” which, like the classes’ speeds, is ill-defined. The various card classes seem to have different speed ranges according to different memory manufacturers. According to Sandisk, for example, Class 4 cards offer read and write speeds of 15 megabytes per second (MBps), Class 6 cards can handle 20MBps, and Class 10 cards reach 30MBps. Kingston, on the other hand, describes its Class 4 cards as delivering a 4MBps data transfer rate, Class 6 as having 15MBps write speed, and Class 10 offering a 40MBps data transfer rate. According to Sandisk, UHS-1 SD cards can transfer up to 45MBps, and according to the SD Association, the maximum transfer speed based on the interface bus used is 310MBps (though this limit won’t be reached by cards for a long time, likely after several faster UHS speed classes are defined).
    However, SD is much more open than Memory Stick, for which no public documentation nor any documented legacy implementation is available. All SD cards can be accessed freely using the well-documented SPI bus.

  2. With no moving parts for less wear and tear, the Standard SD memory card provides reliable performance. SanDisk designed their Standard SD memory cards to withstand harsh operating conditions.

    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.
    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
    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.
    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]
    It is unclear how long flash memory will persist under archival conditions – i.e., benign temperature and humidity with infrequent access with or without prophylactic rewrite. Anecdotal evidence[specify] suggests that the technology is reasonably robust on the scale of years.[citation needed] Datasheets of Atmel’s flash-based “ATmega” microcontrollers typically promise retention times of 20 years at 85 °C (185 °F) and 100 years at 25 °C (77 °F).[78]
    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.

  3. Recommendation: If you are inexperienced with updating Micro SD Card Reader device drivers manually, we highly recommend downloading the Micro SD Card Reader Driver Utility. This tool will download and update the correct Micro SD Card Reader driver versions automatically, protecting you against installing the wrong Micro SD Card Reader drivers.
    This article seems leaned towards USB-C which I feel remains a newer standard that most computer owners don’t have or need yet. Mac and PC’s are so powerful these days that there is less incentive to upgrade to newer models, especially as Apple annoyingly continues to get rid of all ports. There should be more options for the “traditional” USB ports section. For example, @99EE:disqus and @kinnonyee:disqus have pointed out that Lexar Professional Workflow SR2 was not included in the review, although it has rave reviews on Amazon and B&H.
    The advent of flash memory fueled the rise of all-flash arrays. These systems contain only SSDs. They offer advantages in performance, and sometimes reduced operational costs, compared to all disk-based storage arrays. The chief difference, aside from the media, is in the underlying physical architecture used to write data to a storage device.
    A memory card, flash card or memory cartridge is an electronic flash memory data storage device used for storing digital information. These are commonly used in portable electronic devices, such as digital cameras, mobile phones, laptop computers, tablets, PDAs, portable media players, video game consoles, synthesizers, electronic keyboards, and digital pianos.
    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.
    NOR flash is fast on data reads, but it is typically slower than NAND on erases and writes. NOR flash programs data at the byte level. NAND flash programs data in pages, which are larger than bytes, but smaller than blocks. For instance, a page might be 4 kilobytes (KB), while a block might be 128 KB to 256 KB or megabytes in size. NAND flash consumes less power than NOR flash for write-intensive applications.
    The Iogear lacks an indicator light—a useful feature offered on other card readers, including our top pick, that reassured us the device was working during our tests. Unlike the Unitek, which had sturdy slots that worked the way they should, we found that the Iogear’s SD card slot was a bit too shallow, and the microSD card slot on the unit we tested was slightly misaligned. At one point during testing, we were concerned about breaking the microSD card by jamming it into the janky slot. (Removing it is just as difficult.) We also tried inserting our CF card right-side up, but it wouldn’t fit into the Iogear’s CF slot. After around 30 seconds wasting time and risking damage to the slot and card we realized we had to insert our CF card upside down (in relation to the logo and the SD and microSD slots) for the Iogear to recognize it. The Unitek’s slots work intuitively and identify every card right-side up.

    We appreciate your interest in the Nintendo GameCube.  At this time, we haven’t announced any immediate plans to discontinue the sale and distribution of this system, or the games available for it.  In fact, we still have a handful of software titles being developed for the Nintendo GameCube.  For the latest news and information on this system, as well as other Nintendo-related products, please keep an eye on the news section of our website (

    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.
    The microSD card has helped propel the smartphone market by giving both manufacturers and consumers greater flexibility and freedom.[according to whom?] Due to their compact size, microSD cards are used in many[which?] different applications in a large variety[which?] of markets. Action cameras, such as the GoPRO’s Hero and cameras in drones, frequently use microSD cards.[citation needed]
    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.
    The microSD removable miniaturized Secure Digital flash memory cards were originally named T-Flash or TF, abbreviations of TransFlash. TransFlash and microSD cards are functionally identical allowing either to operate in devices made for the other.[62] SanDisk had conceived microSD when its chief technology officer and the chief technology officer of Motorola concluded that current memory cards were too large for mobile phones. The card was originally called T-Flash, but just before product launch, T-Mobile sent a cease-and-desist order to SanDisk claiming that T-Mobile owned the trademark on T-(anything),[citation needed] and the name was changed to TransFlash. At CTIA Wireless 2005, the SDA announced the small microSD form factor along with SDHC secure digital high capacity formatting in excess of 2 GB with a minimum sustained read and write speed of 17.6 Mbit/s. SanDisk induced the SDA to administer the microSD standard. The SDA approved the final microSD specification on July 13, 2005. Initially, microSD cards were available in capacities of 32, 64, and 128 MB.

  5. SDXC cards utilize the exFAT file system, the use of which is governed by a proprietary license, thereby limiting its legal availability to a small set of operating systems. Therefore, exFAT-formatted SDXC cards are not a universally readable exchange medium.
    Consumer flash storage devices typically are advertised with usable sizes expressed as a small integer power of two (2, 4, 8, etc.) and a designation of megabytes (MB) or gigabytes (GB); e.g., 512 MB, 8 GB. This includes SSDs marketed as hard drive replacements, in accordance with traditional hard drives, which use decimal prefixes.[60] Thus, an SSD marked as “64 GB” is at least 64 × 10003 bytes (64 GB). Most users will have slightly less capacity than this available for their files, due to the space taken by file system metadata.

    Kingston Card Readers quickly transfer all your data – photos, videos, music etc.– so you can wait less and do more. They support a wide variety of formats, including microSD, microSDHC, SD, SDHC, SDXC and CompactFlash.
    When things get a bit more serious, enthusiasts and professionals need to look for the speed of a card, as most DSLRs can produce large Raw files, shoot HD video or capture multiple shots in a single burst, the data streaming through the camera’s buffer will need to be met by a card at the end that can ‘match up’ to its specification to receive all the information. (See below for how to work out the speeds of a card.)
    An SD Card (Secure Digital Card) is an ultra small flash memory card designed to provide high-capacity memory in a small size. SD cards are used in many small portable devices such as digital video camcorders, digital cameras, handheld computers, audio players and mobile phones. In use since 1999, SD Memory Cards are now available in capacities between 16 Megabytes and 1 Gigabyte. An SD card typically measures 32 x 24 x 2.1 mm and weighs approximately 2grams.
    Because of the particular characteristics of flash memory, it is best used with either a controller to perform wear leveling and error correction or specifically designed flash file systems, which spread writes over the media and deal with the long erase times of NOR flash blocks.[58] The basic concept behind flash file systems is the following: when the flash store is to be updated, the file system will write a new copy of the changed data to a fresh block, remap the file pointers, then erase the old block later when it has time.
    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]
    The SDIO family comprises Low-Speed and Full-Speed cards. Both types of SDIO cards support SPI and one-bit SD bus types. Low-Speed SDIO cards are allowed to also support the four-bit SD bus; Full-Speed SDIO cards are required to support the four-bit SD bus. To use an SDIO card as a “combo card” (for both memory and I/O), the host device must first select four-bit SD bus operation. Two other unique features of Low-Speed SDIO are a maximum clock rate of 400 kHz for all communications, and the use of Pin 8 as “interrupt” to try to initiate dialogue with the host device.[57]

  6. Like other types of flash memory card, an SD card of any SD family is a block-addressable storage device, in which the host device can read or write fixed-size blocks by specifying their block number.[citation needed]
    If you’re planning to use your camera, smartphone or camcorder to take high-resolution video, such a 1080P or 4K UHD, you’ll want to make sure you have a large capacity card to avoid needing to empty it after a small amount of footage.
    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.
    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.
    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.
    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.
    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.
