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.
The Iogear lacks an indicator light—a useful feature offered on other card readers, including our top pick, that reassured us the device was working during our tests. Unlike the Unitek, which had sturdy slots that worked the way they should, we found that the Iogear’s SD card slot was a bit too shallow, and the microSD card slot on the unit we tested was slightly misaligned. At one point during testing, we were concerned about breaking the microSD card by jamming it into the janky slot. (Removing it is just as difficult.) We also tried inserting our CF card right-side up, but it wouldn’t fit into the Iogear’s CF slot. After around 30 seconds wasting time and risking damage to the slot and card we realized we had to insert our CF card upside down (in relation to the logo and the SD and microSD slots) for the Iogear to recognize it. The Unitek’s slots work intuitively and identify every card right-side up.
A host device can ask any inserted SD card for its 128-bit identification string (the Card-Specific Data or CSD). In standard-capacity cards (SDSC), 12 bits identify the number of memory clusters (ranging from 1 to 4,096) and 3 bits identify the number of blocks per cluster (which decode to 4, 8, 16, 32, 64, 128, 256, or 512 blocks per cluster). The host device multiplies these figures (as shown in the following section) with the number of bytes per block to determine the card’s capacity in bytes.
A group of vendors, including Intel, Dell, and Microsoft, formed a Non-Volatile Memory Host Controller Interface (NVMHCI) Working Group. The goal of the group is to provide standard software and hardware programming interfaces for nonvolatile memory subsystems, including the “flash cache” device connected to the PCI Express bus.

Prior to the Nintendo GameCube’s release, Nintendo focused resources on the launch of the Game Boy Advance, a handheld game console and successor to the original Game Boy and Game Boy Color. As a result, several games originally destined for the Nintendo 64 console were postponed in favor of becoming early releases on the GameCube. The last first-party game in 2001 for the Nintendo 64 was released in May, a month before the Game Boy Advance’s launch and six months before the GameCube’s, emphasizing the company’s shift in resources. Concurrently, Nintendo was developing software for the GameCube which would provision future connectivity between it and the Game Boy Advance. Certain games, such as The Legend of Zelda: Four Swords Adventures and Final Fantasy Crystal Chronicles, can use the handheld as a secondary screen and controller when connected to the console via a link cable.
A hybrid flash array blends disk and SSDs. Hybrid arrays use SSDs as a cache to speed access to frequently requested hot data, which subsequently is rewritten to back-end disk. Many enterprises commonly archive data from disk as it ages by replicating it to an external magnetic tape library.
Most flash ICs come in ball grid array (BGA) packages, and even the ones that do not are often mounted on a PCB next to other BGA packages. After PCB Assembly, boards with BGA packages are often X-rayed to see if the balls are making proper connections to the proper pad, or if the BGA needs rework. These X-rays can erase programmed bits in a flash chip (convert programmed “0” bits into erased “1” bits). Erased bits (“1” bits) are not affected by X-rays.
In hindsight, the heating issues were probably a major warning sign. After 6 months, I plugged in my reader – and it died. Rather, it didn’t respond at all – no lights or anything, even with a SD card inside! I tested it on multiple computers and operating systems to eliminate the possibility of computer issues or driver problems – no issues. (On Linux, I checked to see if the kernel even saw it – nothing showed up at all, not even a USB error! It’s as if I plugged nothing in…)
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.

In 1997, a graphics hardware design company called ArtX was launched, staffed by twenty engineers who had previously worked at SGI on the design of the Nintendo 64’s graphics hardware. The team was led by Dr. Wei Yen, who had been SGI’s head of Nintendo Operations, the department responsible for the Nintendo 64’s fundamental architectural design.
With most people carrying around smartphones, MP3 players, digital cameras, pocket camcorders, or all of them, flash memory cards have become a requirement for keeping your digital life running smoothly. If you got a shiny new device that can snap photos or play music, odds are (unless, of course, it’s an Apple product) it’s going to use a flash memory card to offer additional storage capacity. To get more granular, it’s most likely going to use some variety of Secure Digital (SD) card. SD has emerged as the dominant flash memory format, but it’s not that simple. There are scores of SD cards of all shapes, sizes, and speeds available, so picking the right one for each device can be slightly confusing.
Eight GameCube games support network connectivity, five with internet support and three with local area network (LAN) support. 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. The official servers were decommissioned in 2007, but players can still connect to fan maintained private servers. Japan received two additional games with internet capabilities, a cooperative RPG, Homeland and a baseball game with downloadable content, Jikkyō Powerful Pro Yakyū 10. 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.
Nevertheless, in order to be fully compliant with the SDXC card specification, many SDXC-capable host devices are firmware-programmed to expect exFAT on cards larger than 32 GB. Consequently, they may not accept SDXC cards reformatted as FAT32, even if the device supports FAT32 on smaller cards (for SDHC compatibility). Therefore, even if a file system is supported in general, it is not always possible to use alternative file systems on SDXC cards at all depending on how strictly the SDXC card specification has been implemented in the host device. This bears a risk of accidental loss of data, as a host device may treat a card with an unrecognized file system as blank or damaged and reformat the card.
Flash memory incorporates the use of floating-gate transistors to store data. Floating-gate transistors, or floating gate MOSFET (FGMOS), is similar to MOSFET, which is a transistor used for amplifying or switching electronic signals. Floating-gate transistors are electrically isolated and use a floating node in direct current (DC). Flash memory is similar to the standard MOFSET, except the transistor has two gates instead of one.
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.
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.
Rob, what do you see in your device manager? Type “Device Manager” in the Windows search area. Under Disk Drives, you should see something like the picture below. If not maybe a Triangle with an “!” inside it. Right click on it, and it should give you the option to search for a driver..

This card arrived quickly (Fulfillment by Amazon, sold by SanDisk + Prime Membership)! I ordered two of them, because ordering individual cards was a little less expensive than ordering them in pairs or quads (go figure???).
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.
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. 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. 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. 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.
The console was announced as the Nintendo GameCube at a press conference in Japan on August 24, 2000, abbreviated as “NGC” in Japan and “GCN” in North America. Nintendo unveiled its software lineup for the sixth generation console at E3 2001, focusing on fifteen launch games, including Luigi’s Mansion and Star Wars Rogue Squadron II: Rogue Leader. Several games originally scheduled to launch with the console were delayed. It is also the first console in the company’s history not to accompany a Super Mario platform game at launch.
