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.
You’ll need a memory card reader to transfer photos to your computer if you don’t fancy lugging around a USB cable for every one of your devices. You’ll be able to get a card reader for each of the above types of memory cards and some come with built in memory and can also function as a USB flash drive. But check the device you’re loading your photos to as some computers, printers and notebooks already come with built-in memory card slots. If you’re using more than one memory card regularly it will probably be worth investing in a multi-card reader, which accept multiple types of memory cards and brands. Some even take as many as 35-in-1.
Speed Class*, UHS Speed Class** and Video Speed Class*** symbols with a number indicate minimum writing speed. This is mainly useful for camcorders, video recorders and other devices with video recording capabilities. Regarding bus mode, it is necessary to use a bus mode fast enough that does not affect memory write speed. C10 is used in High Speed mode or faster, U1 and U3 are used in SDR50/DDR50 or faster, and V60 and V90 are used in UHS-II mode or faster.

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.
I’d be more than happy with the Aukey reader if it was didn’t have the card reading failure. I don’t care about blocking nearby ports, I don’t care about CF support, I don’t care about absolute top speed, I care about having a very small reader for my daily gear kit. And how could the Hyperdrive be blocking “the only other port” when you can simply turn it 180 degrees?

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.

A flash memory chip is composed of NOR or NAND gates. NOR is a type of memory cell created by Intel in 1988. The NOR gate interface supports full addresses, data buses and random access to any memory location. The shelf life of NOR flash is 10,000 to 1,000,000 write/erase cycles.
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. 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.
It is the smallest memory card that can be bought; at 15 mm × 11 mm × 1 mm (about the size of a fingernail), it is about a quarter of the size of a normal-sized SD card. There are adapters that make the small microSD able to fit in devices that have slots for standard SD, miniSD, Memory Stick Duo card, and even USB. But, not all of the different cards can work together. Many microSD cards are sold with a standard SD adapter, so that people can use them in devices that take standard SD but not microSD 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.
The microSD card has helped propel the smartphone market by giving both manufacturers and consumers greater flexibility and freedom.[according to whom?] Due to their compact size, microSD cards are used in many[which?] different applications in a large variety[which?] of markets. Action cameras, such as the GoPRO’s Hero and cameras in drones, frequently use microSD cards.
File fragmentation: where there is not sufficient space for a file to be recorded in a contiguous region, it is split into non-contiguous fragments. This does not cause rotational or head-movement delays as with electromechanical hard drives, but may decrease speed; for instance, by requiring additional reads and computation to determine where on the card the file’s next fragment is stored.
An additional subcategory is a hybrid hard drive that combines a conventional HDD with a NAND flash module. A hybrid hard drive is generally viewed as a way to bridge the divide between rotating media and flash memory.

The Cable Matters reader has similar speeds to the Unitek and Iogear readers. During our SD card tests, the Cable Matters reader had a read speed of 92 MB/s and a write speed of 86 MB/s. When we tested the unit with a microSD card, it had a read and write speed of 92 MB/s and 71 MB/s, respectively. The Cable Matters can also read two cards simultaneously, like our top pick, though its speeds drop sharply. Running an SD and a microSD card at the same time gave us abysmal read and write speeds of 19.5 MB/s and 17.2 MB/s from both cards, respectively. The Unitek gave us decent read and write speeds of 59 MB/s and 49 MB/s when transferring data from two cards at once.
The Secure Digital High Capacity (SDHC) format, announced in January 2006 and defined in version 2.0 of the SD specification, supports cards with capacities up to 32 GB. The SDHC trademark is licensed to ensure compatibility.
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. 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.
Dave, thanks. There wasn’t an item as you suggested under “disk drives” – but after rebooting the notebook with the SD Card inserted, I can now see an SD Host Adaptor (“SDA Standard Compliant SD Host Controller”).
The Secure Digital eXtended Capacity (SDXC) format, announced in January 2009 and defined in version 3.01 of the SD specification, supports cards up to 2 TB (2048 GB), compared to a limit of 32 GB for SDHC cards in the SD 2.0 specification. SDXC adopts Microsoft’s exFAT file system as a mandatory feature.

Host devices that comply with newer versions of the specification provide backward compatibility and accept older SD cards. For example, SDXC host devices accept all previous families of SD memory cards, and SDHC host devices also accept standard SD cards.
Under Unix-like operating systems such as Linux or FreeBSD, SD cards can be formatted using the UFS, Ext2, Ext3, Ext4, btrfs, HFS Plus, ReiserFS or F2FS file system. Additionally under Linux, HFS Plus file systems may be accessed for read/write if the “hfsplus” package is installed, and partitioned and formatted if “hfsprogs” is installed. (These package names are correct under Debian, Ubuntu etc., but may differ on other Linux distributions.)
Retrospectively, Joystiq compared the GameCube’s launch window to its successor, the Wii, noting that the GameCube’s “lack of games” resulted in a subpar launch, and the console’s limited selection of online games damaged its market share in the long run. Time International concluded that the system had low sales figures, because it lacked “technical innovations”.
Latest versions of major operating systems, including Windows Mobile and Android Marshmallow, allow applications to run from microSD cards creating possibilities for new usage models for SD cards in mobile computing markets.
