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 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 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.
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).
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.
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.
MicroSD: In 2005, SanDisk and Motorola teamed up to introduce the original microSD product, then known as TransFlash, as a 128 GB removable card for mobile phones. In June 2016, SanDisk (now part of Western Digital Corp.) launched a suite of 256 GB microSD cards, including Ultra microSDHC and microSDXC UHS-I cards geared for Android-based devices.
Memory cards offer a number of advantages over a hard disk drive (HDD): they are much smaller and lighter, extremely portable, silent, allow more immediate access and are less prone to mechanical damage. However, an HDD still offers a compelling advantage: Although flash prices are coming down, a typical memory card still costs more (and has a lower storage capacity) than a high-capacity HDD.
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.
Long before the console’s launch, Nintendo had developed and patented an early prototype of motion controls for the GameCube, with which developer Factor 5 had experimented for its launch games. An interview quoted Greg Thomas, Sega of America’s VP of Development as saying, “What does worry me is Dolphin’s sensory controllers [which are rumored to include microphones and headphone jacks] because there’s an example of someone thinking about something different.” These motion control concepts would not be deployed to consumers for several years, until the Wii Remote.

Samsung Galaxy Note II owner – card worked great out of the package without any need for formatting in my phone. Just after the 30-day return period had expired, I’ve started noticing the Reading SD Card icon briefly appearing when I wake my phone from sleep. Now, I’m constantly getting read errors on my phone asking me to format my card. After formatting on my computer (tried FAT32 and FAT – on my computer because it does not format on my phone with this error) and then again on my phone (to ensure a correct format), it would briefly work for about an hour and then the reading errors would recur. It’s just a matter of time before complete and utter card failure. The card is a complete failure now with the constant read errors. It simply is not usable. Bought this card on sale (not much of a savings now that I have a useless chunk of plastic). Thought I’d risk it even though SanDisk’s quality has been on the decline, but never again. Who would have thought that SanDisk, once a leader in flash memory, would have fallen so low. I’ve never had any of my Patriot cards fail as miserably as this SanDisk card. I should have suspected the poor quality control by just looking at the cheap grey and red paint job on the card. I highly recommend anyone thinking about buying this card to learn from my mistake and reconsider spending a little more to buy from a quality company.
In March 2006, Samsung announced flash hard drives with a capacity of 4 GB, essentially the same order of magnitude as smaller laptop hard drives, and in September 2006, Samsung announced an 8 GB chip produced using a 40 nm manufacturing process. In January 2008, SanDisk announced availability of their 16 GB MicroSDHC and 32 GB SDHC Plus cards.
If you’re planning to store photos and videos on your memory card, you may need to consider write speed as well as capacity. If your photography needs are fairly basic, such as taking clear, quality pictures of family vacations or get-togethers, any average memory card, like a Speed Class 10, should provide sufficient speed and reliability. However, if you plan on taking video including 4K Ultra HD or HRD, you’ll require faster speed and more capacity.
Nintendo is traditionally recognized for releasing innovative, first-party games, most notably from the Super Mario and The Legend of Zelda series. These first-party series continued on the GameCube and bolstered the console’s popularity. As a publisher, Nintendo also focused on creating new franchises, such as Pikmin and Animal Crossing, and renewing some that skipped the N64 platform, most notably the Metroid series with the release of Metroid Prime. The console also saw success with the critically acclaimed The Legend of Zelda: The Wind Waker and Super Mario Sunshine, and its best-selling game, Super Smash Bros. Melee, which sold 7 million copies worldwide. Despite Nintendo’s commitment to its software library, however, it was still criticized by some for not featuring enough games during the console’s launch window.
The companies also formed the SD Association (SDA), a non-profit organization, in January 2000 to promote and create SD Card standards. SDA today has about 1,000 member companies. The SDA uses several trademarked logos owned and licensed by SD-3C to enforce compliance with its specifications and assure users of compatibility.
Another memory card type used in top-end professional cameras and camcorders is CFast. A variant of CompactFlash, this memory card format has an extremely fast write speed and can be used in cameras that capture the highest quality images and video.
SDHC host devices are required to accept older SD cards. However, older host devices do not recognize SDHC or SDXC memory cards, although some devices can do so through a firmware upgrade. Older Windows operating systems released before Windows 7 require patches or service packs to support access to SDHC cards.
The GameCube features two memory card ports for saving game data. Nintendo released three official memory card options: Memory Card 59 in gray (512 KB), Memory Card 251 in black (2 MB), and Memory Card 1019 in white (8 MB). (Though often advertised in Megabits, as 4 Mb, 16 Mb, and 64 Mb respectively.) A few games were known to have compatibility issues with the Memory Card 1019, and at least two games have save issues with any size. Memory cards with larger capacities were released by third-party manufacturers.
Look no further than this guide for your NAND flash memory essentials. Your copy includes an in-depth breakdown of SLC, MLC and TLC NAND, a performance and cost comparison of NAND vs. DRAM and NOR, and how the NAND flash shortage affects SSD supply and pricing.
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.
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.
Specified in SD version 3.01, 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.
If our pick is sold out or unavailable, the Iogear USB-C 3-Slot Card Reader is a good second choice. Like our top pick, the Iogear delivers fast speeds with SD, microSD, and CF cards, although it can read only one card at a time. The Iogear is a little longer than the Unitek, but it’s thinner and lighter, with a shorter connecting cable. It lacks an indicator light, though, and its slots weren’t as easy to use as the Unitek’s. Using the Iogear’s CF card slot, in particular, isn’t intuitive. We spent 30 seconds trying to fit the CF card into its slot—risking damage to the card and the slot—before realizing that it had to be inserted upside down relative to the logo and the other slots. The Unitek’s slots, on the other hand, recognized every card right-side up. The Iogear comes with a three-year warranty, longer than that of any of its competition.
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).
eBay determines trending price through a machine learned model of the product’s sale prices within the last 90 days. “New” refers to a brand-new, unused, unopened, undamaged item, and “Used” refers to an item that has been used previously.
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. (See Other file systems below).
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.
Samsung Pro 64 GB microSDXC original (left) and counterfeit (right): The counterfeit claims to have 64 GB in capacity, but only 8 GB (Class 4 speed) are usable: When trying to write more than 8 GB, data loss occurs. Also used for SanDisk 64 GB fakes.
At 2.2 inches wide, the Unitek is a little broader than all of our other picks (even the bulky Kingston USB 3.0 High-Speed Media Reader), but it’s only 2.4 inches long, around a half inch shorter than most of the competition. It also comes with a white, 12-inch connecting cable attached to its back. It’s easily pocketable and very light at 2.2 ounces, and its glossy silver finish makes it better-looking than some of the other card readers we’ve tested.
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.
The speed class rating does not totally characterize card performance. Different cards of the same class may vary considerably while meeting class specifications. A card’s speed depends on many factors, including:
SanDisk Ultra CompactFlash memory cards deliver the ideal combination of reliability, value, and performance for casual photographers with entry to mid-range DSLRs. Capture the moment with ultra fast shot speeds and save time moving files to your computer with transfer speeds of up to 50MB/s1 (8GB – 32GB2). For dependability and solid performance, you can count on SanDisk Ultra CompactFlash memory cards to capture and store your favorite pictures and videos. That’s why for memories that can’t be missed, photographers worldwide choose SanDisk..
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.
To play online, players must install an official broadband or modem adapter in their system since the GameCube does not have out of the box network capabilities. Nintendo never commissioned any servers or internet services to interface with the console, but allowed other publishers to do so and made them responsible for managing the online experiences for their games.

Official pin numbers for each card type (top to bottom): MMC, SD, miniSD, microSD. This shows the evolution from the older MMC, on which SD is based. NOTE: This drawing doesn’t show 8 new UHS-II contacts that were added in spec 4.0.
The standard was introduced in August 1999 by joint efforts between SanDisk, Panasonic (Matsushita Electric) and Toshiba as an improvement over MultiMediaCards (MMC), 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.
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 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).
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.
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.
And just because someone at EBGames told you production stopped months ago does not mean the system really is out of production. He could be biased towards another system or heard it from a buddy of his. Either way, his information is not the most accurate.
The standard SD card is the largest and has been in use the longest, measuring 32 by 24 by 2.1 mm (HWD), weighing 2 grams, and showing the signature cut-corner profile SD cards are known for. Most digital cameras you can buy today use standard-size SD cards. Even though they’re the largest SD card, they’re still very small, and are dwarfed by the CompactFlash cards used by professional photographers in high-end digital cameras, like the $5,000 Canon 1D Mark IV. However, the cards can get even smaller.
