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.
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-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).
In September 2006, SanDisk announced the 4 GB miniSDHC.[61] Like the SD and SDHC, the miniSDHC card has the same form factor as the older miniSD card but the HC card requires HC support built into the host device. Devices that support miniSDHC work with miniSD and miniSDHC, but devices without specific support for miniSDHC work only with the older miniSD card. Since 2008, miniSD cards were no longer produced.

Specified in version 4.0, further raises the data transfer rate to a theoretical maximum of 156 MB/s (full duplex) or 312 MB/s (half duplex) using an additional row of pins[31][32] (a total of 17 pins for full-size and 16 pins for micro-size cards).[27]
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.
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.
CompactFlash (CF) cards offer very high storage capacities and fast processing times. They were first introduced by Sandisk in 1994 and were widely used, but now they are usually only found in the most advanced DSLRs. Last year Canon chose CompactFlash as the recording media for use in its new lineup of professional high definiton (HD) video cameras.
Poor quality, significant overheating, and potentially dangerous, faulty power circuit. Cheaper does not necessarily mean better. Go with the Transcend USB 3.0 SD/MicroSD Card Reader and save yourself the headache.
The low-level interface to flash memory chips differs from those of other memory types such as DRAM, ROM, and EEPROM, which support bit-alterability (both zero to one and one to zero) and random access via externally accessible address buses.
In 2005, Toshiba and SanDisk developed a NAND flash chip capable of storing 1 GB of data using multi-level cell (MLC) technology, capable of storing two bits of data per cell. In September 2005, Samsung Electronics announced that it had developed the world’s first 2 GB chip.[61]
Recommendation: If you are inexperienced with updating Micro SD Card Reader device drivers manually, we highly recommend downloading the Micro SD Card Reader Driver Utility. 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.
Based on the above and other problem reports, it appears that Dell, Asus, and Lenovo are not updating their SD drivers. I could not find a new driver on the Dell site and found a note indicating that there was no intention to update the driver for my XPS. What did Microsoft do in Windows 10 to discourage these manufacturers from updating their SD reader drivers?
Compared to NOR flash, replacing single transistors with serial-linked groups adds an extra level of addressing. Whereas NOR flash might address memory by page then word, NAND flash might address it by page, word and bit. Bit-level addressing suits bit-serial applications (such as hard disk emulation), which access only one bit at a time. Execute-in-place applications, on the other hand, require every bit in a word to be accessed simultaneously. This requires word-level addressing. In any case, both bit and word addressing modes are possible with either NOR or NAND flash.
Several manufacturers make microSD cards and they consume different amounts of electrical power. Most are in the range of 0-100 mA at a supply voltage of 3.3 V. TwinMos technologies says that the cards carry a maximum of 45 mA during transfer.[7] Toshiba lists 80-100 mA.[8]
In flash memory, each memory cell resembles a standard MOSFET, except that the transistor has two gates instead of one. On top is the control gate (CG), as in other MOS transistors, but below this there is a floating gate (FG) insulated all around by an oxide layer. The FG is interposed between the CG and the MOSFET channel. Because the FG is electrically isolated by its insulating layer, electrons placed on it are trapped until they are removed by another application of electric field (e.g. Applied voltage or UV as in EPROM). Counter-intuitively, placing electrons on the FG sets the transistor to the logical “0” state. Once the FG is charged, the electrons in it screen (partially cancel) the electric field from the CG, thus, increasing the threshold voltage (VT1) of the cell. This means that now a higher voltage (VT2) must be applied to the CG to make the channel conductive. In order to read a value from the transistor, an intermediate voltage between the threshold voltages (VT1 & VT2) is applied to the CG. If the channel conducts at this intermediate voltage, the FG must be uncharged (if it was charged, we would not get conduction because the intermediate voltage is less than VT2), and hence, a logical “1” is stored in the gate. If the channel does not conduct at the intermediate voltage, it indicates that the FG is charged, and hence, a logical “0” is stored in the gate. The presence of a logical “0” or “1” is sensed by determining whether there is current flowing through the transistor when the intermediate voltage is asserted on the CG. In a multi-level cell device, which stores more than one bit per cell, the amount of current flow is sensed (rather than simply its presence or absence), in order to determine more precisely the level of charge on the FG.
SD/SDHC/SDXC memory cards have a “Protected Area” on the card for the SD standard’s security function; a standard formatter may erase it, causing problems if security is used. The SD Association provides freely-downloadable SD Formatter software to overcome these problems for Windows and Mac OS X.[108] The SD Formatter does not format the “Protected Area”, and the Association recommends the use of appropriate application software or SD-compatible device that provides SD security function to format the “Protected Area” in the memory card.
Antony Adshead, a storage editor with Computer Weekly, explains the basics of flash storage technology and offers a rundown of MLC, eMLC, SLC and TLC flash, commenting on their place in the market and the use cases they are suited to.
The Iogear is about an inch skinnier and a half inch longer than the Unitek, measuring in at 3 by 1.6 by 0.5 inches. Although it’s technically shorter and lighter than the Unitek, its rounded top makes it appear bulkier. It also has a shiny black body that attracts fingerprints, and a short, 4.3-inch connecting cable attached to its back.
Many older video game consoles used memory cards to hold saved game data. Cartridge-based systems primarily used battery-backed volatile RAM within each individual cartridge to hold saves for that game. Cartridges without this RAM may have used a password system, or wouldn’t save progress at all. The Neo Geo AES, released in 1990 by SNK, was the first video game console able to use a memory card. AES memory cards were also compatible with Neo-Geo MVS arcade cabinets, allowing players to migrate saves between home and arcade systems and vice versa.[7] Memory cards became commonplace when home consoles moved to read-only optical discs for storing the game program, beginning with systems such as the TurboGrafx-CD and Sega-CD.
The GameCube introduced a proprietary miniDVD optical disc format as the storage medium for the console, capable of storing up to 1.5 GB of data.[37] The technology was designed by Matsushita Electric Industrial (now Panasonic Corporation) which utilizes a proprietary copy-protection scheme – different from the Content Scramble System (CSS) found in standard DVDs – to prevent unauthorized reproduction.[38] The Famicom Data Recorder, Famicom Disk System, SNES-CD, and 64DD had explored various complementary storage technologies, but the GameCube was Nintendo’s first console to move away from cartridge-based media altogether.[39] The GameCube’s 1.5 GB mini-disc have sufficient room for most games, although a few games require an extra disc, higher video compression, or removal of content present in versions on other consoles. By comparison, the PlayStation 2 and Xbox, also sixth-generation consoles, both use 8.5 GB Dual-Layer DVDs.
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 next step is to form a cylindrical hole through these layers. In practice, a 128 Gibit V-NAND chip with 24 layers of memory cells requires about 2.9 billion such holes. Next the hole’s inner surface receives multiple coatings, first silicon dioxide, then silicon nitride, then a second layer of silicon dioxide. Finally, the hole is filled with conducting (doped) polysilicon.[24]
Getting yourself in a memory card muddle and not sure which card to buy? We look at memory card speeds and the fastest memory card on the market to help explain the differences so you can find out what’s the best card for you.
It was designed to compete with the Memory Stick, a DRM product that Sony had released the year before. Developers predicted that DRM would induce wide use by music suppliers concerned about piracy.[59]
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.
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.
We were really surprised with this little USB SD/Micro SD/MMC reader. The design is reminiscent of older USB flash sticks and as such may be a little awkward when used on a laptop machine in one’s lap. It comes complete with a small cap to go over the USB port, and like flash sticks, can get lost quite easily, but that’s all we could find to complain about.

  1. 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.

    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.
    A malfunctioning SD card can be repaired using specialized equipment, as long as the middle part, containing the flash storage, is not physically damaged. The controller can in this way be circumvented.[120][121]
    On March 6, 2009, Pretec introduced the first SDXC card,[65] a 32 GB card with a read/write speed of 400 Mbit/s. But only early in 2010 did compatible host devices come onto the market, including Sony’s Handycam HDR-CX55V camcorder, Canon’s EOS 550D (also known as Rebel T2i) Digital SLR camera,[66] a USB card reader from Panasonic, and an integrated SDXC card reader from JMicron.[67] The earliest laptops to integrate SDXC card readers relied on a USB 2.0 bus, which does not have the bandwidth to support SDXC at full speed.[68]
    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.

    Flash memory is a type of electronically erasable programmable read only memory (EEPROM), but may also be a standalone memory storage device such as a USB drive. EEPROM is a type of data memory device using an electronic device to erase or write digital data. Flash memory is a distinct type of EEPROM, which is programmed and erased in large blocks.
    The Hyperdrive 3-in-1 Connection Kit gave us SD read and write speeds of 20 MB/s, though we should have been getting at least 80 MB/s on a UHS-I connection. And its design obstructs other plugs—most notably blocking the power plug on a Dell XPS 13, and the only other port on the MacBook Pro (13-inch, late 2016, Two Thunderbolt 3 Ports).

  2. 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.
    Windows Vista (SP1) and later[21] and OS X (10.6.5 and later) support exFAT out of the box.[22][23] (Windows XP and Server 2003 can support exFAT via an optional update from Microsoft.)[24] Most BSD and Linux distributions do not, for legal reasons; users must manually install third-party implementations of exFAT (as a FUSE module) in order to be able to mount exFAT-formatted volumes.[25] However, SDXC cards can be reformatted to use any file system (such as ext2, UFS, or VFAT), alleviating the restrictions associated with exFAT availability.
    Many personal computers of all types, including tablets and mobile phones, use SD cards, either through built-in slots or through an active electronic adapter. Adapters exist for the PC card, ExpressBus, USB, FireWire, and the parallel printer port. Active adapters also let SD cards be used in devices designed for other formats, such as CompactFlash. The FlashPath adapter lets SD cards be used in a floppy disk drive.
    Hope in the future that Amazon punishes vendors who ship inferior, counterfeit, or products different than described or pictured. Right now, the only way I see to determine if this might be the case is to S L O W L Y read the 1 and 2 Star reviews for a product. Four or maybe even two years ago, you could comfortably make a purchase based on 4-Stars or above. No more – especially on these commodity products where confusion exists regarding product specifications. [On this product alone: SD vs. SDXC vs. SDHC; Suitability of Capacity; Choice of writing speed for application. For in-depth information see SDCard dot ORG] An overall rating is NO LONGER a sufficient criterion for a purchasing decision since many of these commodity type products have their reviews gamed by paid reviewers.
    Flash memory has many features. It is a lot less expensive than EEPROM and does not require batteries for solid-state storage such as static RAM (SRAM). It is non-volatile, has a very fast access time and has a higher resistance to kinetic shock compared to a hard disc drive. Flash memory is extremely durable and can withstand intense pressure or extreme temperatures. It can be used for a wide array of applications such as digital cameras, mobile phones, laptop computers, PDAs (personal digital assistants), digital audio players and solid-state drives (SSDs).
    Cards that comply with UHS show Roman numerals ‘I’, ‘II’ or ‘III’ next to the SD card logo,[27][34] and report this capability to the host device. Use of UHS-I requires that the host device command the card to drop from 3.3-volt to 1.8-volt operation over the I/O interface pins and select the four-bit transfer mode, while UHS-II requires 0.4-volt operation.

    NOR and NAND flash memory differ in architecture and design characteristics. NOR flash uses no shared components and can connect individual memory cells in parallel, enabling random access to data. A NAND flash cell is more compact and has fewer bit lines, stringing together floating gate transistors to increase storage density.
    Anecdotal evidence suggests NAND flash drives are not wearing out to the degree once feared. Flash drive manufacturers have improved endurance and reliability through error correction code algorithms, wear leveling and other technologies.
