Most NAND devices are shipped from the factory with some bad blocks. These are typically marked according to a specified bad block marking strategy. By allowing some bad blocks, the manufacturers achieve far higher yields than would be possible if all blocks had to be verified good. This significantly reduces NAND flash costs and only slightly decreases the storage capacity of the parts.
The Unitek was fast and stable when we tested its SD, microSD, and CF speeds—many other readers gave us inconsistent results or didn’t work at all. The Unitek can also read two cards simultaneously—although you lose some speed when transferring data from both cards at once. It doesn’t support UHS-II speeds, but there aren’t any USB-C readers that support both CF and UHS-II SD cards yet. The Unitek is small and light, with a long attached cable and a useful indicator light so you can see when your card is connected or transferring data. It comes with a two-year warranty, about the same as its competitors.
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.
4) Write speed is very quick from PC to this card. Bursts of over 30 MB/s with an average around 10-15 MB/s. Faster than the Cruzer Flash Drives SanDisk Cruzer Fit 16 GB x2 = 32GB USB Flash Drive SDCZ33-016G-B35-2PK w/ Everything But Stromboli (TM) Lanyard I reviewed elsewhere, but the utility of this SDHC card for moving files is limited by equipment that does not have a built-in card reader.

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.
The first thing to be certain of when purchasing an SD card is what kind works in your camera. Is it a regular SD card or a microSD card? Keep in mind, many microSD cards come with adapters that let you use them in devices that normally take SD cards.
In February 2014, SanDisk announced a new microSD card, the MicroSDXC. At the time, the cards held up to 128GB. To enable this amount of storage capacity on a removable microSD card, SanDisk developed a proprietary technique that allows for 16 memory die to be vertically stacked, each shaved to be thinner than a strand of hair. At the time of their release, these cards had capacities ranging from 8GB to 128GB, with the prices ranging from $29.99 to $199.99. [6][5]

Common flash devices such as USB flash drives and memory cards provide only a block-level interface, or flash translation layer (FTL), which writes to a different cell each time to wear-level the device. This prevents incremental writing within a block; however, it does help the device from being prematurely worn out by intensive write patterns.
Compatibility: Windows® 8/8.1 (32/64bit), 7 (32/64bit), Server 2008 (32/64), Vista(32/64), Server 2003 (32/64) XP(32/64), 2000 Apple® Mavericks (10.9) OSX Mountain Lion (10.8), Lion (10.7), Snow Leopard (10.6) Linux Google Chrome™ OS Android
The presence of a notch, and the presence and position of a tab, have no effect on the SD card’s operation. A host device that supports write protection should refuse to write to an SD card that is designated read-only in this way. Some host devices do not support write protection, which is an optional feature of the SD specification. Drivers and devices that do obey a read-only indication may give the user a way to override it.
UHS speed class is designed for SDHC and SDXC memory cards. These cards are a higher speed and utilize a different data bus that doesn’t work in non-UHS compatible devices. You’ll want one of these cards for Full HD recording and for taking continuous high-resolution photos, like burst shot mode used for sports photography. A higher speed UHS card, like a U3 can be used for recording video in 4K.
Eight GameCube games support network connectivity, five with internet support and three with local area network (LAN) support.[63][64] The only internet capable games released in western territories are three role-playing games (RPGs) in Sega’s Phantasy Star series: Phantasy Star Online Episode I & II, Phantasy Star Online Episode I & II Plus, and Phantasy Star Online Episode III: C.A.R.D. Revolution.[63] The official servers were decommissioned in 2007, but players can still connect to fan maintained private servers.[65][66] Japan received two additional games with internet capabilities, a cooperative RPG, Homeland and a baseball game with downloadable content, Jikkyō Powerful Pro Yakyū 10.[63][64] Lastly, three racing games have LAN multiplayer modes: 1080° Avalanche, Kirby Air Ride, and Mario Kart: Double Dash!!. These three games can be forced over the internet with third-party PC software capable of tunneling the GameCube’s network traffic.[67][68]
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.
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.[15]
I ordered the IOGEAR SD/MicroSD/MMC Card Reader/Writer GFR204SD and got it in the mail about three days after ordering [impressive]. As some other reviewers have noted, it does feel a little flimsy, and care should be taken to insert and remove it AS STRAIGHT AS YOU CAN from whatever device you use it in, especially when it’s a very tight fit into the USB port.

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.

An individual memory cell is made up of one planar polysilicon layer containing a hole filled by multiple concentric vertical cylinders. The hole’s polysilicon surface acts as the gate electrode. The outermost silicon dioxide cylinder acts as the gate dielectric, enclosing a silicon nitride cylinder that stores charge, in turn enclosing a silicon dioxide cylinder as the tunnel dielectric that surrounds a central rod of conducting polysilicon which acts as the conducting channel.[24]
Secure Digital cards are used in many consumer electronic devices, and have become a widespread means of storing several gigabytes of data in a small size.[citation needed] Devices in which the user may remove and replace cards often, such as digital cameras, camcorders, and video game consoles, tend to use full-sized cards.[citation needed] Devices in which small size is paramount, such as mobile phones, tend to use microSD cards.[citation needed]
As of 2013, V-NAND flash architecture allows read and write operations twice as fast as conventional NAND and can last up to 10 times as long, while consuming 50 percent less power. They offer comparable physical bit density using 10-nm lithography, but may be able to increase bit density by up to two orders of magnitude.[24]
We appreciate your interest in the Nintendo GameCube.  At this time, we haven’t announced any immediate plans to discontinue the sale and distribution of this system, or the games available for it.  In fact, we still have a handful of software titles being developed for the Nintendo GameCube.  For the latest news and information on this system, as well as other Nintendo-related products, please keep an eye on the news section of our website (
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.
They still have gamecubes here in my small city, I’d love to hear that they get more wii’s (I have one). My friend that works there says employees are allowed to reserve them, I only got mine cause they forgot to hold the consoles this shipment. 
To erase a NOR flash cell (resetting it to the “1” state), a large voltage of the opposite polarity is applied between the CG and source terminal, pulling the electrons off the FG through quantum tunneling. Modern NOR flash memory chips are divided into erase segments (often called blocks or sectors). The erase operation can be performed only on a block-wise basis; all the cells in an erase segment must be erased together. Programming of NOR cells, however, generally can be performed one byte or word at a time.
