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]
When reformatting an SD card with a capacity of at least 32 MB (65536 logical sectors or more), but not more than 2 GB, FAT16B with partition type 06h and EBPB 4.1[103] is recommended if the card is for a consumer device. (FAT16B is also an option for 4 GB cards, but it requires the use of 64 kiB clusters, which are not widely supported.) FAT16B does not support cards above 4 GB at all.

What I had been unaware of when I first bought this card is that memory cards have speed ratings which indicate how quickly they can process the data you want to write on them. To further complicate things, there are two types of ratings, Speed Class and Ultra High Speed. Speed classes come in four ratings, C2, C4, C6, and C10, which means they can write data at a rate of 2MB/s, 4MB/s, 6MB/s, and 10MB/s, respectively, or UHS comes in UHS U1 and U3, which writes at speeds of 10MB/s and 30MB/s. The higher the MB/s, the better the card.
There are wide discrepancies in memory access speed depending on the SD memory card manufacturer and brand. Varying speeds make it difficult to make out which card can surely record streaming contents. Recording video require a constant minimum write speed to avoid ‘frame drop’ during recording for a smooth playback. The SD Association has defined various Speed Class standards to answer a demand for advanced video quality recording. Speed Class symbols indicated to host and card products help users decide the best combination for reliable recording (no frame drop). There are three kinds of speed indications:
Secure Digital cards are ubiquitous in consumer electronic devices and have become the dominant means of storing several gigabytes of data in a small form factor. This new device is extremely compact but big on compatibility within the SD memory card family. The unit supports the very latest in memory card format, SDXC (Secure Digital Extended Capacity). 
I haven’t really been able to find reviews for this reader that thoroughly address the issue of car connectivity [and I’ll admit I gave a few a quick once-over and was just trying to key in on a few words]. I bought this item on a gamble because of that. I figured that for the price, if it wouldn’t work with my car, I can always find another use for it, with barely a dent in my wallet.
CompactFlash (CF) cards offer very high storage capacities and fast processing times. They were first introduced by Sandisk in 1994 and were widely used, but now they are usually only found in the most advanced DSLRs. Last year Canon chose CompactFlash as the recording media for use in its new lineup of professional high definiton (HD) video cameras.

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.

Flash memory stores information in an array of memory cells made from floating-gate transistors. In single-level cell (SLC) devices, each cell stores only one bit of information. Multi-level cell (MLC) devices, including triple-level cell (TLC) devices, can store more than one bit per cell.
On April 22, 2002, veteran third party Nintendo console developer Factor 5 announced its 3D audio software development kit for GameCube developers, MusyX. In collaboration with Dolby Laboratories, it provides motion-based surround sound encoded as Dolby Pro Logic II.[32]

Partnering with Nintendo in 1998, ArtX began the complete design of the system logic and of the graphics processor (codenamed “Flipper”)[9] of Nintendo’s sixth generation video game console, reportedly bearing the early internal code name of “N2000”.[10] At Nintendo’s press conference in May 1999, the console was first publicly announced as “Project Dolphin”, the successor to the Nintendo 64.[8][11] Subsequently, Nintendo began providing development kits to game developers. Nintendo also formed a strategic partnership with IBM for the production of Dolphin’s CPU, code-named “Gekko”.
Well I really didn’t think this topic would generate such intense controversy. I thought it would be relativley straightforward and easy to find out the answer, but I guess things are more complicated than that. Hopefully we’ll get an official comment from Nintendo about it one or another. I personally don’t care if they discontinue it, I’m not going to be offended by that decision, I just wish they were more upfront about it.
An individual memory cell is made up of one planar polysilicon layer containing a hole filled by multiple concentric vertical cylinders. The hole’s polysilicon surface acts as the gate electrode. The outermost silicon dioxide cylinder acts as the gate dielectric, enclosing a silicon nitride cylinder that stores charge, in turn enclosing a silicon dioxide cylinder as the tunnel dielectric that surrounds a central rod of conducting polysilicon which acts as the conducting channel.[24]
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.
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).
The Lightning to SD Card Camera Reader supports standard photo formats, including JPEG and RAW, along with SD and HD video formats, including H.264 and MPEG-4. It supports data transfer at up to USB 3 speeds on the 12.9-inch and 10.5-inch iPad Pro, and up to USB 2 speeds on the 9.7-inch iPad Pro and all other iPad and iPhone models.*
Video Speed Class defines a set of requirements for UHS cards to match the modern MLC NAND flash memory[19] and supports progressive 4K and 8K video with minimum sequential writing speeds of 6-90 MB/s.[17][34][40] The graphical symbols use ‘V’ followed by a number designating write speed (V6, V10, V30, V60, and V90).
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.
The proprietary nature of the complete SD specification affects embedded systems, laptop computers, and some desktop computers; many desktop computers do not have card slots, instead using USB-based card readers if necessary. These card readers present a standard USB mass storage interface to memory cards, thus separating the operating system from the details of the underlying SD interface. However, embedded systems (such as portable music players) usually gain direct access to SD cards and thus need complete programming information. Desktop card readers are themselves embedded systems; their manufacturers have usually paid the SDA for complete access to the SD specifications. Many notebook computers now include SD card readers not based on USB; device drivers for these essentially gain direct access to the SD card, as do embedded systems.
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.
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.
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.

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.
An essential for any GameCube owner. Excellent price, decent build (hard plastic, but it feels sturdy). 64 MB is plenty of storage (excessive, really), but it ensures that lack of memory will never be a problem you have to face.
Retrospectively, Joystiq compared the GameCube’s launch window to its successor, the Wii, noting that the GameCube’s “lack of games” resulted in a subpar launch, and the console’s limited selection of online games damaged its market share in the long run.[60] Time International concluded that the system had low sales figures, because it lacked “technical innovations”.[75]

Most NAND devices are shipped from the factory with some bad blocks. These are typically marked according to a specified bad block marking strategy. By allowing some bad blocks, the manufacturers achieve far higher yields than would be possible if all blocks had to be verified good. This significantly reduces NAND flash costs and only slightly decreases the storage capacity of the parts.
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.

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.
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:
In addition to digital cameras, many portable media players feature SD memory card slots for storing music, data, and video. The Standard SD memory card gives you plenty of space for all your tunes, TV shows, video clips, and more.
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.
IOGEAR’s GFR204SD Secure Digital cards are ubiquitous in consumer electronic devices and have become the dominant means of storing several gigabytes of data in a small form factor. This new product supports the very latest memory cards available in today’s market, SDXC (Secure Digital Extended Capacity). The SD/MicroSD/MMC Card Reader/Writer is a solution for hi-speed, bi-directional image and data transfer. Images and data can be transferred quickly from Secure Digital Card (SD), MultiMedia Card (MMC), or MicroSD memory cards to PCs or Macs.
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
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.

When you plug it in, the clear LED lights up as a bright blue – something you may wish to cover with a piece of scotch tape if bright blue lights at night bother you! When you’re reading or copying files to the SD card, the little blue light on top blinks to indicate data activity.
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.
