I ordered the IOGEAR SD/MicroSD/MMC Card Reader/Writer GFR204SD and got it in the mail about three days after ordering [impressive]. As some other reviewers have noted, it does feel a little flimsy, and care should be taken to insert and remove it AS STRAIGHT AS YOU CAN from whatever device you use it in, especially when it’s a very tight fit into the USB port.
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.
With most people carrying around smartphones, MP3 players, digital cameras, pocket camcorders, or all of them, flash memory cards have become a requirement for keeping your digital life running smoothly. If you got a shiny new device that can snap photos or play music, odds are (unless, of course, it’s an Apple product) it’s going to use a flash memory card to offer additional storage capacity. To get more granular, it’s most likely going to use some variety of Secure Digital (SD) card. SD has emerged as the dominant flash memory format, but it’s not that simple. There are scores of SD cards of all shapes, sizes, and speeds available, so picking the right one for each device can be slightly confusing.
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.

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]
With its fast data rates and reliable performance, the SanDisk Ultra CompactFlash Memory Card helps you get the most out of your camera, camcorders and other devices that support CompactFlash memory cards. This CompactFlash card comes in capacities of up to 32GB2, so you can keep shooting without worrying about running out of space.
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.
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.
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]
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.
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.
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.
The most common memory cards typically come in 8GB, 16GB, 32GB, 64GB and 128GB capacities. However, some high-capacity cards can now hold terabytes (TB) of data. One TB is equal to 1,000GB. Often these larger memory cards are SDXC cards, so you’ll want to check your device and make sure it’s compatible with these cards before purchasing.
mSATA flash drives mainly used in laptops, netbooks and other portable computing devices. The mSATA specification maps SATA signals to an internally mounted PCIe card in a computer motherboard. The M.2 SSD form factor for ultrathin computing devices is generally considered to be the eventual replacement for mSATA-based flash memory cards.
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.
I bought this to run on my Droid Razr Maxx HD phone. Worked fairly smoothly at first. Then in the two days prior to total failure, it kept unmounting from my phone. After that nothing. Won’t read on my phone or pc at all. Dead in the water. I like the price, the capacity, and the brand name. Wish I could rate it higher, but when something fails so badly, there is no value in it or any way I could give it a higher overall rating.
Worked fine for about 90 days then started showing “reading card” on start ups and suddenly NOTHING. From other reviews it appears to be a common problem with Samsung Galaxy phones. I have a S3 and Note II and the card no longer works on either. If you have the same combo and are coming up on 90 days, backup everything frequently and wait for “Sudden Death”, other than that its a great value IF SanDisk PAYS YOU to use it. To be fair perhaps Samsung is part of the problem – but so far no one appears to be part of a solution.
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]
Flash is the least expensive form of semiconductor memory. Unlike dynamic random access memory (DRAM) and static RAM (SRAM), flash memory is nonvolatile, offers lower power consumption and can be erased in large blocks. Also, on the plus side, NOR flash offers fast random reads, while NAND flash is fast with serial reads and writes.
Most SD cards are 2.1 mm (0.083 inches) thick, compared to 1.4 mm (0.055 inches) for MMCs. The SD specification defines a card called Thin SD with a thickness of 1.4 mm, but they occur only rarely, as the SDA went on to define even smaller form factors.
Toshiba developed flash memory from EEPROM (electrically erasable programmable read-only memory) in the early 1980s and introduced it to the market in 1984. The two main types of flash memory are named after the NAND and NOR logic gates. The individual flash memory cells exhibit internal characteristics similar to those of the corresponding gates.
The adapter works to import image files to the iOS Photos app. I’m running iOS 9.2 on an iPhone 6 Plus and iPad Pro. The transfer speed on the iPad Pro is faste The adapter works to import image files to the iOS Photos app. I’m running iOS 9.2 on an iPhone 6 Plus and iPad Pro. The transfer speed on the iPad Pro is faster, rated at USB 3.0 speeds as opposed to the iPhone’s USB 2.0 speed. I transferred a Nikon D800 RAW file, which are huge 36 megapixel files, in about 2 seconds on the iPad and roughly 5 seconds on the iPhone. If you’re working with RAW files, make sure your camera model is supported by iOS. Once the files are transferred to your Photos app, you will still need an app to convert the RAW files to file types compatible with the photo editor apps you use. 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)

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.
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.
Saving games without a Memory card for a Game Cube is like Trying to save data without Hard Drive! A Memory Card to a Game Cube is what a Hard Drive is to a Computer! Get a Memory Card for the Game Cube or better yet get Two one for slot A and another for slot B! That way you have more space on the second card so when Memory Card in Slot A runs outta Space you can move data to Slot B

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.
In September 2006, SanDisk announced the 4 GB miniSDHC.[61] Like the SD and SDHC, the miniSDHC card has the same form factor as the older miniSD card but the HC card requires HC support built into the host device. Devices that support miniSDHC work with miniSD and miniSDHC, but devices without specific support for miniSDHC work only with the older miniSD card. Since 2008, miniSD cards were no longer produced.
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]
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:

NAND was developed by Toshiba a year after NOR was produced. It is faster, has a lower cost per bit, requires less chip area per cell and has added resilience. The shelf life of a NAND gate is approximately 100,000 write/erase cycles. In NOR gate flash every cell has an end connected to a bit line and the other end connected to a ground. If a word line is “high” then the transistor proceeds to lower the output bit line.
