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.
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.
The SanDisk Extreme Pro UHS-II Card USB-C Reader was our previous recommendation for UHS-II speeds, but it costs nearly three times as much as the Verbatim, and it doesn’t have a microSD slot. Its SD card read and write speeds were about 39 MB/s and 31 MB/s faster than the Verbatim’s, though, and it has a useful indicator light and a simple design.
I have done it and it works… Go into disk management (word of warning my issue might have been different from yours.). You should see your sd card reader. I fixed this by right clicking on the large box which corresponds to the sd card at the bottom of the window and I clicked “Change drive letter and paths” assign a letter and you should be fine if your issue is the same as mine.

The SanDisk Standard SD memory card has a blank writeable white space on the front of the card, making it easy to identify your different cards. Use one memory card for all your vacation photos, and another for all your favorite music–the label makes it easy to see which is which at a glance. Rather than inserting cards into your digital device to review the content, simply look at the label and go.
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.
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)

Bought this for me and my wife shortly after we bought a GameCube (to relive our childhood) a little less than 2 years ago. So far it has worked flawlessly with all games played, and is not even close to filling up. Item received was slightly different in shape than the picture advertised, but that is purely aesthetic.
Whatever, you need to be careful when deleting your memory card. Ideally, you only need to delete the card when you change your phone. When your phone is actively accessing the memory card, but  the connection is disconnected, normally, the card does not know how to handle it. So this may cause your picture can not open correctly, your app crashes. or even for a very sluggish phone,  when the phone is completely turned off the SD card can  be removed. But many phones have an “Uninstall SD Card” option in their settings, so you can switch them when you need .
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.
The microSD removable miniaturized Secure Digital flash memory cards were originally named T-Flash or TF, abbreviations of TransFlash. TransFlash and microSD cards are functionally identical allowing either to operate in devices made for the other.[62] SanDisk had conceived microSD when its chief technology officer and the chief technology officer of Motorola concluded that current memory cards were too large for mobile phones. The card was originally called T-Flash, but just before product launch, T-Mobile sent a cease-and-desist order to SanDisk claiming that T-Mobile owned the trademark on T-(anything),[citation needed] and the name was changed to TransFlash. At CTIA Wireless 2005, the SDA announced the small microSD form factor along with SDHC secure digital high capacity formatting in excess of 2 GB with a minimum sustained read and write speed of 17.6 Mbit/s. SanDisk induced the SDA to administer the microSD standard. The SDA approved the final microSD specification on July 13, 2005. Initially, microSD cards were available in capacities of 32, 64, and 128 MB.
Flash memory is used in enterprise server, storage and networking technology, as well as in a wide range of consumer devices, including USB flash drives, mobile phones, digital cameras, tablet computers, PC cards in notebook computers and embedded controllers. For instance, NAND flash-based solid-state drives are often used to accelerate the performance of I/O-intensive applications. NOR flash memory is often used to hold control code, such as the basic input/output system (BIOS), in a PC.

This tool will download and update the correct Micro SD Card Reader driver versions automatically, protecting you against installing the wrong Micro SD Card Reader drivers.
In 1997, a graphics hardware design company called ArtX was launched, staffed by twenty engineers who had previously worked at SGI on the design of the Nintendo 64’s graphics hardware. The team was led by Dr. Wei Yen, who had been SGI’s head of Nintendo Operations, the department responsible for the Nintendo 64’s fundamental architectural design.[7][8]
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.
USB drive: This portable plug-and-play flash storage device is inserted into a computer’s standard USB port. USB drives ushered in the demise of floppy disks and, to some extent, the reduced use of compact discs.
The speed class rating was based on request from movie and video companies, as video recording in different formats and resolutions requires certain write speeds when recording to the card. As a result, the goal of the class ratings is to allow consumers to easily identify cards that meet the minimum level of required performance based on their use or application of the host device. Below is a listing of typical applications for each speed class.
The one-bit SD protocol was derived from the MMC protocol, which envisioned the ability to put up to three cards on a bus of common signal lines. The cards use open collector interfaces, where a card may pull a line to the low voltage level; the line is at the high voltage level (because of a pull-up resistor) if no card pulls it low. Though the cards shared clock and signal lines, each card had its own chip select line to sense that the host device had selected it.[citation needed]
Despite the additional transistors, the reduction in ground wires and bit lines allows a denser layout and greater storage capacity per chip. (The ground wires and bit lines are actually much wider than the lines in the diagrams.) In addition, NAND flash is typically permitted to contain a certain number of faults (NOR flash, as is used for a BIOS ROM, is expected to be fault-free). Manufacturers try to maximize the amount of usable storage by shrinking the size of the transistors.
The beauty of today’s digital cameras is the ability to shoot lots of images and wait till later to worry about which ones to keep. But to truly harness the power of your digital camera, you’ll need an SD card or two to make sure you never run out of space when you need it most. SD memory cards are like tiny USB drives that add capacity to your camera. SD cards are also super handy for popping into a memory card reader to transfer your photos to your computer or to print directly from a photo printer. No matter what you’re looking for – from the biggest SD card to smaller SD cards for sale – Best Buy is here to help.
The Lexar Professional USB 3.0 Dual-Slot Reader was our former pick for USB-A ports, but Micron has since shuttered the Lexar brand. It was a little speedier than the Kingston when it worked—its read and write speeds were 27 MB/s and 12 MB/s faster than the Kingston, respectively—but the first two Lexar units we tested gave us only UHS-I speeds instead of faster UHS-II speeds on both Mac and Windows.
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.
The SDA announced the microSD format at CTIA Wireless 2005 on March 14, 2005, and the final microSD details were announced on July 13, 2005. When they were first sold, the microSD format was sold in sizes of 32, 64, and 128 MB. SanDisk made a 4 GB microSD card on July 2006, at first costing $99 (USD). Since then, the prices for flash memory devices have become much lower. At the time of April 2009, the same 4 GB card could be bought for as low as $12 (USD) at department stores, and by May 2009, for as low as $6 (USD) at online electronics stores. In January 2010, a 16 GB micro SD card class 2 cost about $40 (USD), and a 4 GB class 2 micro SD card about $8 (USD).
V-NAND uses a charge trap flash geometry (pioneered in 2002 by AMD)[citation needed] that stores charge on an embedded silicon nitride film. Such a film is more robust against point defects and can be made thicker to hold larger numbers of electrons. V-NAND wraps a planar charge trap cell into a cylindrical form.[24]

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]
Version 1.01 let an SDSC card use a 4-bit field to indicate 1,024 or 2,048 bytes per block instead.[30] Doing so enabled cards with 2 GB and 4 GB capacity, such as the Transcend 4 GB SD card and the Memorette 4GB SD card.
