The above types of memory cards are usually associated with consumer devices, such as digital cameras, smartphones and tablets. The cards come in varying sizes, and storage capacities typically correspond directly to their price.
10 MB/s Class 10 (C10) Class 1 (U1) Class 10 (V10) Full HD (1080p) video recording and consecutive recording of HD stills (High Speed bus, Class C10), real-time broadcasts and large HD video files (UHS bus, Classes U1 and V10)
Flash memory cards come in a range of sizes, including 2 GB, 4 GB and 8 GB. Once you know which media cards are compatible with your devices, choose the size based on the type of files you’ll be storing. If a memory card isn’t quite what you need, browse our assortment of USB memory sticks for file storage and transfer, some of which can store up to 16 GB.
One more recent application for flash memory is as a replacement for hard disks. Flash memory does not have the mechanical limitations and latencies of hard drives, so a solid-state drive (SSD) is attractive when considering speed, noise, power consumption, and reliability. Flash drives are gaining traction as mobile device secondary storage devices; they are also used as substitutes for hard drives in high-performance desktop computers and some servers with RAID and SAN architectures.
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]
Intel Corporation introduced the first commercial NOR type flash chip in 1988.[8] NOR-based flash has long erase and write times, but provides full address and data buses, allowing random access to any memory location. This makes it a suitable replacement for older read-only memory (ROM) chips, which are used to store program code that rarely needs to be updated, such as a computer’s BIOS or the firmware of set-top boxes. Its endurance may be from as little as 100 erase cycles for an on-chip flash memory,[9] to a more typical 10,000 or 100,000 erase cycles, up to 1,000,000 erase cycles.[10] NOR-based flash was the basis of early flash-based removable media; CompactFlash was originally based on it, though later cards moved to less expensive NAND flash.
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.

In most cases, once the Micro SD Card is inserted in your phone, your phone automatically starts scanning the card, pulls out all the information MicroSD Card  needs, and immediately stores information in the appropriate location. So that Micro SD Card will start working directly.

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:
In 2012, the CompactFlash Association announced the CFast 2.0 Standard, promising read and write speeds of more than double what was then the current standard. In September 2013, SanDisk released the first CFast 2.0 card, billed as the world’s fastest memory card, promising read speeds of up to 450MB/s and write speeds of up to 350MB/s.

SDHC card: This card has the same form factor as an SD card, with specifications that define SDHC card capacities from 4 GB to 32 GB. These devices were developed to tackle high-definition video and high-resolution images. Although SD cards will work in an SDHC device, an SDHC card will not function in an SD card-based digital camera or card reader.
At initial power-up or card insertion, the host device selects either the Serial Peripheral Interface (SPI) bus or the one-bit SD bus by the voltage level present on Pin 1. Thereafter, the host device may issue a command to switch to the four-bit SD bus interface, if the SD card supports it. For various card types, support for the four-bit SD bus is either optional or mandatory.[30]
Flash memory is a non-volatile memory chip used for storage and for transfering data between a personal computer (PC) and digital devices. It has the ability to be electronically reprogrammed and erased. It is often found in USB flash drives, MP3 players, digital cameras and solid-state drives.
Long before the console’s launch, Nintendo had developed and patented an early prototype of motion controls for the GameCube, with which developer Factor 5 had experimented for its launch games.[19][20] An interview quoted Greg Thomas, Sega of America’s VP of Development as saying, “What does worry me is Dolphin’s sensory controllers [which are rumored to include microphones and headphone jacks] because there’s an example of someone thinking about something different.” These motion control concepts would not be deployed to consumers for several years, until the Wii Remote.[20]

NAND was developed by Toshiba a year after NOR was produced. It is faster, has a lower cost per bit, requires less chip area per cell and has added resilience. The shelf life of a NAND gate is approximately 100,000 write/erase cycles. In NOR gate flash every cell has an end connected to a bit line and the other end connected to a ground. If a word line is “high” then the transistor proceeds to lower the output bit line.
With the increasing speed of modern CPUs, parallel flash devices are often much slower than the memory bus of the computer they are connected to. Conversely, modern SRAM offers access times below 10 ns, while DDR2 SDRAM offers access times below 20 ns. Because of this, it is often desirable to shadow code stored in flash into RAM; that is, the code is copied from flash into RAM before execution, so that the CPU may access it at full speed. Device firmware may be stored in a serial flash device, and then copied into SDRAM or SRAM when the device is powered-up.[71] Using an external serial flash device rather than on-chip flash removes the need for significant process compromise (a process that is good for high-speed logic is generally not good for flash and vice versa). Once it is decided to read the firmware in as one big block it is common to add compression to allow a smaller flash chip to be used. Typical applications for serial flash include storing firmware for hard drives, Ethernet controllers, DSL modems, wireless network devices, etc.
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.
I bought this to run on my Droid Razr Maxx HD phone. Worked fairly smoothly at first. Then in the two days prior to total failure, it kept unmounting from my phone. After that nothing. Won’t read on my phone or pc at all. Dead in the water. I like the price, the capacity, and the brand name. Wish I could rate it higher, but when something fails so badly, there is no value in it or any way I could give it a higher overall rating.
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.
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.
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.
Samsung Galaxy Note II owner – card worked great out of the package without any need for formatting in my phone. Just after the 30-day return period had expired, I’ve started noticing the Reading SD Card icon briefly appearing when I wake my phone from sleep. Now, I’m constantly getting read errors on my phone asking me to format my card. After formatting on my computer (tried FAT32 and FAT – on my computer because it does not format on my phone with this error) and then again on my phone (to ensure a correct format), it would briefly work for about an hour and then the reading errors would recur. It’s just a matter of time before complete and utter card failure. The card is a complete failure now with the constant read errors. It simply is not usable. Bought this card on sale (not much of a savings now that I have a useless chunk of plastic). Thought I’d risk it even though SanDisk’s quality has been on the decline, but never again. Who would have thought that SanDisk, once a leader in flash memory, would have fallen so low. I’ve never had any of my Patriot cards fail as miserably as this SanDisk card. I should have suspected the poor quality control by just looking at the cheap grey and red paint job on the card. I highly recommend anyone thinking about buying this card to learn from my mistake and reconsider spending a little more to buy from a quality company.
The SanDisk Ultra CompactFlash memory card has plenty of room to accommodate high-resolution image formats, such as RAW and JPEG. Available in capacities up to 32GB2, it can store thousands of photos and your favorite video clips.
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.
SDIO cards support most of the memory commands of SD cards. SDIO cards can be structured as eight logical cards, although currently, the typical way that an SDIO card uses this capability is to structure itself as one I/O card and one memory card.
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.

In 2001, SD card  is mainly for digital cameras, mobile phones, laptops and game consoles  from the beginning of development to popular. These memory cards are combined in a small size (32 x 24 x 2.1 mm) and good strength and have become a practical tool for storing different types of data, (from photos and videos to files and applications)  in recent years.
EPROM and EEPROM cells operate similarly to flash memory in how data is written, or programmed, but differ from flash memory in how data is erased. An EPROM is erased by removing the chip from the system and exposing the array to ultraviolet light. An EEPROM erases data electronically at the byte level, while flash memory erases data electronically at the block level.

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.
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?
