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 think it’s pretty cool you can use standard SD and Micro SD in it, but I opted to use my 16GB Micro SDHC from my old phone because standard SD sticks WAY out (be sure to insert the Micro SD upside down). The Micro SD still sticks out from the side of the reader about 1/4″, and I’m curious to know why they couldn’t have designed the reader to accept Micro SD from the rear of it so you won’t accidentally tug on it when inserting/removing the reader.
Overall, SD is less open than CompactFlash or USB flash memory drives. Those open standards can be implemented without paying for licensing, royalties, or documentation. (CompactFlash and USB flash drives may require licensing fees for the use of the SDA’s trademarked logos.)
This card writes at a C4 speed (as indicated by the number 4 encircled by a C on the label). It’s a decent speed for smaller files, but considering a RAW photo files can be rather large, if you’re shooting high res, RAW files, this is not the card for you. It will absolutely freeze up your camera.
While larger is better, you need to make sure your device can use the larger card. The SD/SDHC/SDXC classification isn’t just for cards, but for devices as well. Older digital cameras can only read SD cards, making SDHC cards useless. Similarly, cameras that aren’t SDXC-compatible won’t accept 64GB cards. Most current devices are SDHC compatible, but double-check your older devices before getting SDHC cards, and check the specs on your newer gear before getting SDXC cards.
The Unitek USB-C Card Reader is the best SD card reader for most people because it produced reliably fast speeds during our SD, microSD, and CF tests, and it has a pocketable design (with a useful indicator light) that’s easy to use. It’s also affordable at around $20, and comes with a two-year warranty.

Two major flash device manufacturers, Toshiba and Samsung, have chosen to use an interface of their own design known as Toggle Mode (and now Toggle V2.0). This interface isn’t pin-to-pin compatible with the ONFI specification. The result is a product designed for one vendor’s devices may not be able to use another vendor’s devices.
IOGEAR’s GFR204SD Secure Digital cards are ubiquitous in consumer electronic devices and have become the dominant means of storing several gigabytes of data in a small form factor. This new product supports the very latest memory cards available in today’s market, SDXC (Secure Digital Extended Capacity). The SD/MicroSD/MMC Card Reader/Writer is a solution for hi-speed, bi-directional image and data transfer. Images and data can be transferred quickly from Secure Digital Card (SD), MultiMedia Card (MMC), or MicroSD memory cards to PCs or Macs.
Also in early 2010, commercial SDXC cards appeared from Toshiba (64 GB), Panasonic (64 GB and 48 GB), and SanDisk (64 GB). In early 2011, Centon Electronics, Inc. (64 GB and 128 GB) and Lexar (128 GB) began shipping SDXC cards rated at Speed Class 10. Pretec offered cards from 8 GB to 128 GB rated at Speed Class 16.
Worked fine for about 90 days then started showing “reading card” on start ups and suddenly NOTHING. From other reviews it appears to be a common problem with Samsung Galaxy phones. I have a S3 and Note II and the card no longer works on either. If you have the same combo and are coming up on 90 days, backup everything frequently and wait for “Sudden Death”, other than that its a great value IF SanDisk PAYS YOU to use it. To be fair perhaps Samsung is part of the problem – but so far no one appears to be part of a solution.
The microSD format was made by the company SanDisk. It was first called T-Flash, and then TransFlash, before being named microSD when it started to be used by the SD Card Association (SDA). Other flash card formats approved by the SDA include miniSD and standard SD card.
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.
And just because someone at EBGames told you production stopped months ago does not mean the system really is out of production. He could be biased towards another system or heard it from a buddy of his. Either way, his information is not the most accurate.
I’ve long been a fan of Sandisk, and have faithfully used their compact flash memory cards in all my digital cameras, so imagine my surprise to have two 16 GB and two 32 GB cards fail in two different Samsung Galaxy SIII phones so far, taking all data with them. The cards cannot be accessed or formatted, either in the phone or on the computer. I’ve finally contacted Sandisk support, but after reading a lot of review on the web concerning this issue (and trying all the various workarounds posted), I’m not confident that Sandisk will be able to help me. There frankly should be NO WAY for an SD interface to make a card unusable, short of physically destroying it with overvoltage, period. I’m an embedded systems engineer (30+ years experience) and there is NO EXCUSE for Sandisk cards failing like this, unless the phone is doing something evil electrically to them. Please beware, and back up your files often, because it WILL FAIL eventually.
It is unclear how long flash memory will persist under archival conditions – i.e., benign temperature and humidity with infrequent access with or without prophylactic rewrite. Anecdotal evidence[specify] suggests that the technology is reasonably robust on the scale of years. Datasheets of Atmel’s flash-based “ATmega” microcontrollers typically promise retention times of 20 years at 85 °C (185 °F) and 100 years at 25 °C (77 °F).
Electrons are trapped in the floating gate whether or not a device containing the flash memory cell is receiving power as a result of electrical isolation created by the oxide layer. This characteristic enables flash memory to provide persistent storage.
Another memory card type used in top-end professional cameras and camcorders is CFast. A variant of CompactFlash, this memory card format has an extremely fast write speed and can be used in cameras that capture the highest quality images and video.
I bought this during black friday and I got a huge discount using my rewards points also. I primarlly use it for my Galaxy Note 2. After 2 months, the phone says that the sd card was unexpectedly unmouted. Then my card was not recognized and blank. I could not reformat it in any way since my computer and any other devices can not recognize it. After a successfull fix, 2 days later same thing happen and now I can not get it to work at all. I do not know who to get a hold on to get this fixed. But it is a bummer since I it is a nice size and value. But it just failed horribly.
Many ASICs are pad-limited, meaning that the size of the die is constrained by the number of wire bond pads, rather than the complexity and number of gates used for the device logic. Eliminating bond pads thus permits a more compact integrated circuit, on a smaller die; this increases the number of dies that may be fabricated on a wafer, and thus reduces the cost per die.
Capture and store all your memories with the affordable and reliable SanDisk Standard SD 2 GB memory card. Ideal for use with point-and-shoot digital cameras and other devices that feature SD and SDHC card slots, the SanDisk Standard SD and SDHC memory cards come in capacities of up to 32 GB1, so you’ll have plenty of storage for all your photos, videos, tunes, and more. And now the Standard memory card features a writeable label, making it easier than ever to keep everything organized.
Like most memory card formats, SD is covered by numerous patents and trademarks. Royalties for SD card licences are imposed for manufacture and sale of memory cards and host adapters (US$1,000/year plus membership at US$1,500/year), but SDIO cards can be made without royalties.
Each NOR flash cell is larger than a NAND flash cell – 10 F2 vs 4 F2 – even when using exactly the same semiconductor device fabrication and so each transistor, contact, etc. is exactly the same size – because NOR flash cells require a separate metal contact for each cell.
Secure Digital cards are ubiquitous in consumer electronic devices and have become the dominant means of storing several gigabytes of data in a small form factor. This new device is extremely compact but big on compatibility within the SD memory card family. The unit supports the very latest in memory card format, SDXC (Secure Digital Extended Capacity).

Well I really didn’t think this topic would generate such intense controversy. I thought it would be relativley straightforward and easy to find out the answer, but I guess things are more complicated than that. Hopefully we’ll get an official comment from Nintendo about it one or another. I personally don’t care if they discontinue it, I’m not going to be offended by that decision, I just wish they were more upfront about it.

Nintendo sold 22 million GameCube units worldwide during its lifespan, placing it slightly behind the Xbox’s 24 million, and well behind the PlayStation 2’s 153 million. The GameCube’s predecessor, the Nintendo 64, outperformed it as well selling nearly 33 million units. The console was able to outsell the short-lived Dreamcast, however, which yielded 9.13 million unit sales. In September 2009, IGN ranked the GameCube 16th in its list of best gaming consoles of all time, placing it behind all three of its sixth-generation competitors: the PlayStation 2 (3rd), the Dreamcast (8th), and the Xbox (11th). As of March 31, 2003, the GameCube had sold 9.55 million units worldwide, falling short of Nintendo’s initial goal of 10 million consoles.
In applications that require sustained write throughput, such as video recording, the device might not perform satisfactorily if the SD card’s class rating falls below a particular speed. For example, a high-definition camcorder may require a card of not less than Class 6, suffering dropouts or corrupted video if a slower card is used. Digital cameras with slow cards may take a noticeable time after taking a photograph before being ready for the next, while the camera writes the first picture.
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.
Like it’s smaller brethren, this Sandisk Extreme Pro incredibly fast shot-to-shot performance for use with burst mode, even in extreme heat or freezing conditions. Makes large files more rapid to save, increasing speeds up to a potential 250MB/s.
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.
The Verbatim has a slimmer and lighter design than most of our other picks, at 3 by 1.3 by 0.6 inches and 0.2 ounces respectively. In exchange for its smaller size, you have to deal with a short, 2.8-inch connecting cable that makes it impossible to lay the device flat while you’re using it. When you’re not transferring data, though, you can store the connecting cable neatly in a space on the underside of the device. None of our other picks have built-in cable management.
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.
A single-level NOR flash cell in its default state is logically equivalent to a binary “1” value, because current will flow through the channel under application of an appropriate voltage to the control gate, so that the bitline voltage is pulled down. A NOR flash cell can be programmed, or set to a binary “0” value, by the following procedure:
In practice, flash file systems are used only for memory technology devices (MTDs), which are embedded flash memories that do not have a controller. Removable flash memory cards and USB flash drives have built-in controllers to perform wear leveling and error correction so use of a specific flash file system does not add any benefit.
NOR and NAND flash get their names from the structure of the interconnections between memory cells. In NOR flash, cells are connected in parallel to the bit lines, allowing cells to be read and programmed individually. The parallel connection of cells resembles the parallel connection of transistors in a CMOS NOR gate. In NAND flash, cells are connected in series, resembling a NAND gate. The series connections consume less space than parallel ones, reducing the cost of NAND flash. It does not, by itself, prevent NAND cells from being read and programmed individually.
The flash memory chips inside them are sized in strict binary multiples, but the actual total capacity of the chips is not usable at the drive interface. It is considerably larger than the advertised capacity in order to allow for distribution of writes (wear leveling), for sparing, for error correction codes, and for other metadata needed by the device’s internal firmware.
I bought this card for my Samsung Galaxy S II (T-Mobile T-989) and couldn’t be happier. I’ve got about 15 games, 10 apps, and 200+ songs on it and barely put a dent in it. The speed is also amazing…real fast. I work in a very dusty construction type environment in Michigan, outdoors, year-round, so the durability is also a nice plus. Water resistant (submersed) for up to 72 hrs and temp range of -13 to 185. Sandisk really got it right with this one.
Hewlett Packard Enterprise and SanDisk are partnering on a similar initiative to develop storage-class memory based on SanDisk’s nonvolatile resistive random-access memory (ReRAM) technology, which would be used to design a new class of SSDs.
