It takes up the most space of all our picks, measuring 3.5 by 2 by 0.6 inches, and it weighs 4 ounces. The Kingston card reader isn’t terrible to look at, despite the loud red-and-white design on its top (including a large, red “Kingston” logo that doubles as an indicator light), but it isn’t as attractive as other readers we tested. It comes bundled with a removable, 43-inch connecting cable. None of the other readers we tested had a cable that was this long, or removable.

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).
As the feature size of flash memory cells reaches the 15-16 nm minimum limit, further flash density increases will be driven by TLC (3 bits/cell) combined with vertical stacking of NAND memory planes. The decrease in endurance and increase in uncorrectable bit error rates that accompany feature size shrinking can be compensated by improved error correction mechanisms.[84] Even with these advances, it may be impossible to economically scale flash to smaller and smaller dimensions as the number of electron holding capacity reduces. Many promising new technologies (such as FeRAM, MRAM, PMC, PCM, ReRAM, and others) are under investigation and development as possible more scalable replacements for flash.[85]
Flash memory architecture includes a memory array stacked with a large number of flash cells. A basic flash memory cell consists of a storage transistor with a control gate and a floating gate, which is insulated from the rest of the transistor by a thin dielectric material or oxide layer. The floating gate stores the electrical charge and controls the flow of the electrical current. 
SPI bus mode: Serial Peripheral Interface Bus is primarily used by embedded microcontrollers. This bus type supports only a 3.3-volt interface. This is the only bus type that does not require a host license.

ArtX was acquired by ATI in April 2000, whereupon the Flipper graphics processor design had already been mostly completed by ArtX and was not overtly influenced by ATI.[7][9] In total, ArtX team cofounder Greg Buchner recalled that their portion of the console’s hardware design timeline had arced from inception in 1998 to completion in 2000.[7] Of ATI’s acquisition of ArtX, an ATI spokesperson said, “ATI now becomes a major supplier to the game console market via Nintendo. The Dolphin platform is reputed to be king of the hill in terms of graphics and video performance with 128-bit architecture.”[12]
Write speed is how fast images can be saved onto a memory card. This is a critical need, especially if your camera takes high-resolution images, burst pictures or HD video. If you have a slower memory card, you may have to wait for the memory card to finish writing before you can take additional shots, which could cause you to miss the perfect photo. If your card is too slow to properly handle video, it may cause dropped frames, inferior quality, or stop recording altogether. So if you’re doing sports photography, or taking video, make sure to look for a higher write speed.

Memory cards, just like your electronics, are an investment. You may want to take added steps to protect them. Plus, cases can help organize multiple memory cards while keeping them handy. Cases come in a wide variety, from simple plastic cases for individual cards to multicard aluminum organizers.
The most prominent factor in choosing a memory card is what device you’ll be using it in. Most devices have a specific set of memory cards that are compatible with them. A smartphone or tablet may have only one slot, while a higher-end DSLR or mirrorless camera can have several. Check your device or owner’s manual, and take note of what formats you’ll be able to choose from.
MiniSD cards, the least frequently used format these days, measure 21.5 by 20 by 1.4 mm (HWD) and weigh just a gram, making them just over a third the volume and taking up just over half the area of a full-size SD card. Instead of cut corners, miniSD cards have a tapered corner to help you orient the card when putting it in a slot. This design aspect follows with the smallest of the SD cards, the microSD card.
Because of the series connection and removal of wordline contacts, a large grid of NAND flash memory cells will occupy perhaps only 60% of the area of equivalent NOR cells[50] (assuming the same CMOS process resolution, for example, 130 nm, 90 nm, or 65 nm). NAND flash’s designers realized that the area of a NAND chip, and thus the cost, could be further reduced by removing the external address and data bus circuitry. Instead, external devices could communicate with NAND flash via sequential-accessed command and data registers, which would internally retrieve and output the necessary data. This design choice made random-access of NAND flash memory impossible, but the goal of NAND flash was to replace mechanical hard disks, not to replace ROMs.
It’s the most compact card reader we tested, measuring 2.4 by 1 by 0.4 inches and weighing just 0.3 ounces. The Cable Matters also has an attached, 6-inch cable and a pleasant blue indicator light on top so you know when it’s in use. In testing we found—after wasting time trying to insert them right-side up—that the slots are oriented so you have to insert both SD cards and microSD cards upside down for the card reader to identify them. Once you’ve loaded your microSD and SD cards, you have to flip the card reader back around to see its indicator light.
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]
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.

Contemporary reception of the GameCube was generally positive. The console was praised for its controller, extensive software library and high-quality games, but was criticized for its exterior design and lack of features. Nintendo sold 21.74 million GameCube units worldwide before it was discontinued in 2007. Its successor, the Wii, which has backward compatibility with most GameCube software, was released in November 2006.
The Kingston had read and write speeds of 186 MB/s and 172 MB/s, respectively, during our SD card test—it’s slower than Verbatim’s USB-C reader, but it had the most consistent performance of the USB-A readers we tested. In our microSD card test, the Kingston had expected read and write speeds of 90 MB/s and 68 MB/s. It was a little slower than our other picks when reading and writing to a CF card, with speeds of 144 MB/s and 136 MB/s, respectively.

xD Picture cards (standing for ‘eXtreme Digital’) are a Fujifilm format used in some (older) Fuji and Olympus cameras, although these brands are now routinely compatible with more standard SD/SDHC technology.
UHS-I and UHS-II cards can use UHS Speed Class rating with two possible grades: class 1 for minimum read/write performance of at least 10 MB/s (‘U1’ symbol featuring number 1 inside ‘U’) and class 3 for minimum write performance of 30 MB/s (‘U3’ symbol featuring 3 inside ‘U’), targeted at recording 4K video.[42] Before November 2013, the rating was branded UHS Speed Grade and contained grades 0 (no symbol) and 1 (‘U1’ symbol). Manufacturers can also display standard speed class symbols (C2, C4, C6, and C10) alongside, or in place of UHS speed class.
2) I put it in the camera, and the Nikon D40 immediately formatted the card and it was ready for use. The information screen said that it was ready to hold 2.2K (2200) pictures. I held down the shutter in continuous mode, and fired off about 20 seconds of pictures (the D40 shoots somewhere around 3 or 3.3 pics per second in burst mode). There was no stutter, lag, etc. when writing to the card. This SDHC card (remember different format than SD, which was the format available when I bought the camera) worked flawlessly in this little test. I buy only SanDisk or Lexar products, and I can say that media from neither company has ever let me down. The two Lexar cards have stored downloaded and erased around 72K pictures over six years, generally at 300-500 pics per download/erase/format cycle and are still going strong with the original capacity intact.

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.

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.
In July 2016, Samsung announced the 4TB Samsung 850 EVO which utilizes their 256 Gb 48-layer TLC 3D V-NAND.[67] In August 2016, Samsung announced a 32 TB 2.5-inch SAS SSD based on their 512 Gb 64-layer TLC 3D V-NAND. Further, Samsung expects to unveil SSDs with up to 100 TB of storage by 2020.[68]
SD cards and host devices initially communicate through a synchronous one-bit interface, where the host device provides a clock signal that strobes single bits in and out of the SD card. The host device thereby sends 48-bit commands and receives responses. The card can signal that a response will be delayed, but the host device can abort the dialogue.[30]
When an SD is inserted, the driver appears in the device manager and a drive letter is assigned. An update request indicates the driver is up-to-date. Uninstalling and reinstalling the driver does not help. There were popups asking to reformat the card, but don’t do it because the card is not the problem. Win 7 read all my cards just fine, and Win 10 does not.
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.
