The SD protocol envisioned the ability to gang 30 cards together without separate chip select lines. The host device would broadcast commands to all cards and identify the card to respond to the command using its unique serial number.[citation needed]
On such SD cards, standard utility programs such as Mac OS X’s “Disk Utility” or Windows’ SCANDISK can be used to repair a corrupted filing system and sometimes recover deleted files. Defragmentation tools for FAT file systems may be used on such cards. The resulting consolidation of files may provide a marginal improvement in the time required to read or write the file,[104] but not an improvement comparable to defragmentation of hard drives, where storing a file in multiple fragments requires additional physical, and relatively slow, movement of a drive head. Moreover, defragmentation performs writes to the SD card that count against the card’s rated lifespan. The write endurance of the physical memory is discussed in the article on flash memory; newer technology to increase the storage capacity of a card provides worse write endurance.

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.
Another limitation is that flash memory has a finite number of program – erase cycles (typically written as P/E cycles). Most commercially available flash products are guaranteed to withstand around 100,000 P/E cycles before the wear begins to deteriorate the integrity of the storage.[25] Micron Technology and Sun Microsystems announced an SLC NAND flash memory chip rated for 1,000,000 P/E cycles on 17 December 2008.[26]
Nintendo developed stereoscopic 3D technology for the GameCube, and one launch game, Luigi’s Mansion, supports it. However, the feature was never enabled outside of development. 3D televisions were not widespread at the time, and it was deemed that compatible displays and crystals for the add-on accessories would be too cost-prohibitive for the consumer.[43][44][45] Another unofficial feature are two audio Easter eggs that can be invoked when the console is turned on. When the power is activated with the “Z” button on the Player 1 controller held down, a more whimsical startup sound is heard in place of the standard one. With four controllers connected, holding down the “Z” button on all four simultaneously produces a “ninja-like” tune at startup.[46]
Speed Class*, UHS Speed Class** and Video Speed Class*** symbols with a number indicate minimum writing speed. This is mainly useful for camcorders, video recorders and other devices with video recording capabilities. Regarding bus mode, it is necessary to use a bus mode fast enough that does not affect memory write speed. C10 is used in High Speed mode or faster, U1 and U3 are used in SDR50/DDR50 or faster, and V60 and V90 are used in UHS-II mode or faster.
If you are interested in an SD card for a DSLR, look at something like the Lexar Professional 600x 32GB SDHC UHS-I Flash Memory Card LSD32GCRBNA600. Since switching to the C10/U1 Lexar, I’ve been infinitely more happy with my camera. The Sandisk C4 32GB remains in my point and shoot, where it’s better suited.

NAND flash also uses floating-gate transistors, but they are connected in a way that resembles a NAND gate: several transistors are connected in series, and the bit line is pulled low only if all the word lines are pulled high (above the transistors’ VT). These groups are then connected via some additional transistors to a NOR-style bit line array in the same way that single transistors are linked in NOR flash.
There remain some aspects of flash-based SSDs that make them unattractive. The cost per gigabyte of flash memory remains significantly higher than that of hard disks.[72] Also flash memory has a finite number of P/E cycles, but this seems to be currently under control since warranties on flash-based SSDs are approaching those of current hard drives.[73] In addition, deleted files on SSDs can remain for an indefinite period of time before being overwritten by fresh data; erasure or shred techniques or software that work well on magnetic hard disk drives have no effect on SSDs, compromising security and forensic examination.
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.
NAND flash has reduced erase and write times, and requires less chip area per cell, thus allowing greater storage density and lower cost per bit than NOR flash; it also has up to 10 times the endurance of NOR flash. However, the I/O interface of NAND flash does not provide a random-access external address bus. Rather, data must be read on a block-wise basis, with typical block sizes of hundreds to thousands of bits. This makes NAND flash unsuitable as a drop-in replacement for program ROM, since most microprocessors and microcontrollers require byte-level random access. In this regard, NAND flash is similar to other secondary data storage devices, such as hard disks and optical media, and is thus highly suitable for use in mass-storage devices, such as memory cards. The first NAND-based removable media format was SmartMedia in 1995, and many others have followed, including:

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.

I have had the same problem with my Dell XPS L502x but the SD card reader will read the slow cards 4gb but when I put a 32 GB xtream it will not read so I have to use a USB card reader , I also have trouble now with the integrated web-cam this will not work through the Windows applications but have done a test online and it works, I have tried bios upgrades and there are no updates on the drives so like we all have been left high and dry !! 
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.

MicroSD cards, which are used in most cell phones and smartphones, are downright Lilliputian, measuring 15 by 11 by 1 mm (HWD) and weighing only half a gram. With a total volume of 165 mm3, you could fit nine microSD cards inside a single SD card (though realistically, with the slight lip found on the end of microSD cards, you could probably only squeeze in six).
A process called Fowler-Nordheim tunneling removes electrons from the floating gate. Either Fowler-Nordheim tunneling or a phenomenon known as channel hot-electron injection traps the electrons in the floating gate.
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.
The console was announced as the Nintendo GameCube at a press conference in Japan on August 24, 2000,[13] abbreviated as “NGC” in Japan[14] and “GCN” in North America.[15] 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.[16] Several games originally scheduled to launch with the console were delayed.[17] It is also the first console in the company’s history not to accompany a Super Mario platform game at launch.[18]
