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.

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.
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. 
xD cards are simply 18-pin NAND flash chips in a special package and support the standard command set for raw NAND flash access. Although the raw hardware interface to xD cards is well understood, the layout of its memory contents—necessary for interoperability with xD card readers and digital cameras—is totally undocumented. The consortium that licenses xD cards has not released any technical information to the public.

On ASUS systems there are USB port issues going on since Windows 8.1. Since SD card reader on these ASUS models is off USB, can you please try the following which is uninstall AI Suite software as suggested in the following blog:
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.
After determining that the SD card supports it, the host device can also command the SD card to switch to a higher transfer speed. Until determining the card’s capabilities, the host device should not use a clock speed faster than 400 kHz. SD cards other than SDIO (see below) have a “Default Speed” clock rate of 25 MHz. The host device is not required to use the maximum clock speed that the card supports. It may operate at less than the maximum clock speed to conserve power.[30] Between commands, the host device can stop the clock entirely.
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.
Kingston offers Flash drives designed for and certified by Microsoft® for use with Windows® To Go. A feature of Windows 8 Enterprise, Windows to Go lets IT administrators provide mobile and contingency workers with secure access to the corporate environment.
The SD protocol envisioned the ability to gang 30 cards together without separate chip select lines. The host device would broadcast commands to all cards and identify the card to respond to the command using its unique serial number.[citation needed]
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:
On such SD cards, standard utility programs such as Mac OS X’s “Disk Utility” or Windows’ SCANDISK can be used to repair a corrupted filing system and sometimes recover deleted files. Defragmentation tools for FAT file systems may be used on such cards. The resulting consolidation of files may provide a marginal improvement in the time required to read or write the file,[104] but not an improvement comparable to defragmentation of hard drives, where storing a file in multiple fragments requires additional physical, and relatively slow, movement of a drive head. Moreover, defragmentation performs writes to the SD card that count against the card’s rated lifespan. The write endurance of the physical memory is discussed in the article on flash memory; newer technology to increase the storage capacity of a card provides worse write endurance.
From the Samsung Pro line, this card offers quick speeds of 80MB/s, and at 16GB you can save plenty of photos and HD videos, plus use it as storage to transfer files to different devices. With a very reasonable price this ticks all the boxes.
At this time, all the leading digital camera manufacturers used SD in their consumer product lines, including Canon, Casio, Fujifilm, Kodak, Leica, Nikon, Olympus, Panasonic, Pentax, Ricoh, Samsung, and Sony. Formerly, Olympus and Fujifilm used XD-Picture Cards (xD cards) exclusively, while Sony only used Memory Stick; by early 2010 all three supported SD.
Multiple chips are often arrayed to achieve higher capacities[59] for use in consumer electronic devices such as multimedia players or GPSs. The capacity of flash chips generally follows Moore’s Law because they are manufactured with many of the same integrated circuits techniques and equipment.
Samsung announced the world’s first EVO Plus 256 GB microSDXC card in May 2016.[85] and in September 2016 Western Digital announced that a prototype of the first 1 TB SDXC card will be demonstrated at Photokina.[86]
The Nintendo GameCube received generally positive reviews following its launch. PC Magazine praised the overall hardware design and quality of games available at launch.[70] CNET gave an average review rating, noting that while the console lacks a few features offered by its competition, it is relatively inexpensive, has a great controller design, and launched a decent lineup of games.[71] In later reviews, criticism mounted against the console often centering on its overall look and feel, describing it as “toy-ish.”[72][73] In the midst of poor sales figures and the associated financial harm to Nintendo, a Time International article called the GameCube an “unmitigated disaster.”[74]
A joint development at Intel and Micron will allow the production of 32-layer 3.5 terabyte (TB) NAND flash sticks and 10 TB standard-sized SSDs. The device includes 5 packages of 16 × 48 GB TLC dies, using a floating gate cell design.[66]
If you use only SD and microSD cards, you should get the Cable Matters USB 3.1 Type-C Dual Slot Card Reader. The Cable Matters reader has similar speeds to the IOGear and Transcend readers, but it doesn’t support CF cards. It’s smaller, lighter, and cheaper than our other top picks, plus it has good speeds and an indicator light. It also comes with only a one-year warranty.
The Memory Card numbers indicated the number of save blocks available on the card, and each number is 5 subtracted from some power of 2. This suggests that 5 save blocks are devoted to some sort of system information. Simple math can be used to find out that each save block is a 8 KB page of data. (For example, (59+5)*x = 512 KB, x = (512 KB)/64, x = 8 KB)
Flash memory evolved from erasable programmable read-only memory (EPROM) and electrically erasable programmable read-only memory (EEPROM). Flash is technically a variant of EEPROM, but the industry reserves the term EEPROM for byte-level erasable memory and applies the term flash memory to larger block-level erasable memory.
I’ve not been able to find another decent-looking SD-only card reader for USB-A (to attach to my PC) so it sucks that the Lexar won’t work for me. Might have to get the Kingston one and put up with the redundant memory stick ports staring at me.
NOTE: As other buyers state, this item say’s Wii memory card on the packaging it comes in. This memory card is actually for a system called Nintendo GameCube. It does work on the Wii but only to save Nintendo Gamecube Games. If you’re looking for a Wii memory card for Wii games, that would an SD card you’re looking for.
Works very well for a third party GC memory card. Used it for about a week and not a single game file has corrupted. If you’re looking for a 1019 block GC memory card but don’t want to shell out the $20, this is what you’re looking for.
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.
USB flash drives are known as the floppy disks of the 21st century. You can see people walking around with them dangling from key chains, backpacks, and even around their necks. These are more resistant to physical abuse than the media cards used in digital cameras.

An SD Card (Secure Digital Card) is an ultra small flash memory card designed to provide high-capacity memory in a small size. SD cards are used in many small portable devices such as digital video camcorders, digital cameras, handheld computers, audio players and mobile phones. In use since 1999, SD Memory Cards are now available in capacities between 16 Megabytes and 1 Gigabyte. An SD card typically measures 32 x 24 x 2.1 mm and weighs approximately 2grams.
In February 2014, SanDisk announced a new microSD card, the MicroSDXC. At the time, the cards held up to 128GB. To enable this amount of storage capacity on a removable microSD card, SanDisk developed a proprietary technique that allows for 16 memory die to be vertically stacked, each shaved to be thinner than a strand of hair. At the time of their release, these cards had capacities ranging from 8GB to 128GB, with the prices ranging from $29.99 to $199.99. [6][5]
