At its outset the Association represented just 14 member companies and has grown into a global alliance comprised of around 1,000 member companies. By developing and adopting SD standards, members enjoy better compatibility of member cards between devices, greatly enhancing consumer enjoyment and convenience.
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.
In our SD card test, the IOGear had read and write speeds of 84 MB/s and 72 MB/s, respectively. When reading and writing to the microSD card, it had speeds of 85 MB/s and 64 MB/s, and in our CF card test, it had read and write speeds of 144 MB/s and 114 MB/s.

You can sometimes help increase the read speed of your card to your computer if you are using a USB 2 or FireWire accessory such as the Lexar UDMA Dual Slot (CF and SD) model or the SanDisk ImageMate Multi-Card USB 2.0 Reader.
NAND relies on ECC to compensate for bits that may spontaneously fail during normal device operation. A typical ECC will correct a one-bit error in each 2048 bits (256 bytes) using 22 bits of ECC, or a one-bit error in each 4096 bits (512 bytes) using 24 bits of ECC. If the ECC cannot correct the error during read, it may still detect the error. When doing erase or program operations, the device can detect blocks that fail to program or erase and mark them bad. The data is then written to a different, good block, and the bad block map is updated.
UHS-II uses an additional row of pins to transfer data faster than UHS-I. Because of that extra row of physical pins, you can use a UHS-II card with a UHS-I camera, and a UHS-I card with a UHS-II camera, but you won’t get UHS-II speeds unless both camera and card support it. Likewise, to get those transfer speeds from your SD card to your computer, both the card and card reader must support it. Only high-end cameras can take advantage of UHS-II SD cards right now, but we expect this to change. In February 2017, the SD Association also introduced UHS-III (PDF) to provide further support for 360-degree, 3D, 4K, and 8K media content, but we expect it will take a year or two before we see memory cards and devices that support the new interface.
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.
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. During its launch weekend, the GameCube sold $100 million worth of GameCube products in North America. The console was sold out in several stores, selling faster than both of its competitors, the Xbox and the PlayStation 2, has initially sold. 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. Other popular games include Star Wars Rogue Squadron II: Rogue Leader And Wave Race: Blue Storm. By early December 2001, the system had sold 600,000 units in the US.
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.

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.)
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.
Please note that Wii systems bought in 2011 or later may not be compatible with Nintendo GameCube software, and accessories that use the Nintendo GameCube Controller Sockets. Click here to find out how to identify if a Wii is compatible with Nintendo GameCube software and accessories.
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. 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. Later, however, Eidos resumed development 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.
CompactFlash drive technology: The forerunner to the SD card, the original CF cards were designed on the Parallel Advanced Technology Attachment standard and were no larger than a matchbook. CF cards included a microcontroller and were used as flash memory storage for high-resolution photography. CF and SD cards lack built-in USB computer device connectivity.
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 searched for advice on how to fix this – consensus seemed to be to uninstall the SDA driver and reinstall it. Fine – except I cannot find a place to download the driver! I have an integrated SD Card reader in my ASUS X012B Notebook PC

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.
If you still need a USB-A card reader for your older computer, or you’re a photographer who wants 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.
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.*

Bad block management is a relatively new feature in NOR chips. In older NOR devices not supporting bad block management, the software or device driver controlling the memory chip must correct for blocks that wear out, or the device will cease to work reliably.
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.
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 Class 2 card can handle sustained writing of data at a rate of 2MB/sec; a Class 4 card achieves 4MB/sec; a Class 8 card 8MB/sec, and so on. However, this is the minimum rate rather than the actual rate. It’s entirely possible a Class 4 SDXC card will also brandish 15MB/s on its exterior – a claim that can only be made as a possible speed rather than a full-time sustainable one.
