Some file systems are designed to distribute usage over an entire memory device without concentrating usage on any part (e.g., for a directory) to prolong the life of simple flash memory devices. Some USB flash drives have this 'wear leveling' feature built into the software controller to prolong device life, while others do not, so it is not necessarily helpful to install one of these file systems.[39]
Original flash memory designs had very limited estimated lifetimes. The failure mechanism for flash memory cells is analogous to a metal fatigue mode; the device fails by refusing to write new data to specific cells that have been subject to many read-write cycles over the device's lifetime. Premature failure of a "live USB" could be circumvented by using a flash drive with a write-lock switch as a WORM device, identical to a live CD. Originally, this potential failure mode limited the use of "live USB" system to special-purpose applications or temporary tasks, such as:
Some manufacturers, aiming at a "best of both worlds" solution, have produced card readers that approach the size and form of USB flash drives (e.g., Kingston MobileLite,[65] SanDisk MobileMate[66]) These readers are limited to a specific subset of memory card formats (such as SD, microSD, or Memory Stick), and often completely enclose the card, offering durability and portability approaching, if not quite equal to, that of a flash drive. Although the combined cost of a mini-reader and a memory card is usually slightly higher than a USB flash drive of comparable capacity, the reader + card solution offers additional flexibility of use, and virtually "unlimited" capacity. The ubiquity of SD cards is such that, circa 2011, due to economies of scale, their price is now less than an equivalent-capacity USB flash drive, even with the added cost of a USB SD card reader.
Quickly transfer files to and from your laptop or desktop using this SanDisk Ultra SDCZ48-064G-A46 USB 3.0 flash drive that features a read speed of up to 80MB/sec. The 64GB capacity offers ample storage space. (Ten times faster than USB 2.0 drives. Write speeds up to 10 times faster than Cruzer USB 2.0 drive.)* *USB 3.0 port required. Based on internal testing; performance may be lower depending upon host device.
“The DataTraveler's tiny metal frame and prominent key ring make it easily portable,” our tester said of this flash drive. He added, “Downloading files off the drive itself is fast and easy, at over 100 MB/s, and it's also one of the cheapest USB 3.0 flash drives you can get.” The downside? “While read speeds were fine, the DataTraveler struggles to actually copy files onto the drive,” our reviewer explained. “Despite supporting USB 3.0, it barely tops write speeds of 10 MB/s, and lacks any other features.” The takeaway: “We'd only recommend this product as a cheap way for business professionals to pass out digital content to clients, or for networking,” he stated.
Also, HP has introduced a USB floppy drive key, which is an ordinary USB flash drive with additional possilibility for performing floppy drive emulation, allowing its usage for updating system firmware where direct usage of USB flash drives is not supported. Desired mode of operation (either regular USB mass storage device or of floppy drive emulation) is made selectable by a sliding switch on the device's housing.[51][52]
Audio tape cassettes and high-capacity floppy disks (e.g., Imation SuperDisk), and other forms of drives with removable magnetic media, such as the Iomega Zip and Jaz drives, are now largely obsolete and rarely used. There are products in today's market that will emulate these legacy drives for both tape and disk (SCSI1/SCSI2, SASI, Magneto optic, Ricoh ZIP, Jaz, IBM3590/ Fujitsu 3490E and Bernoulli for example) in state-of-the-art Compact Flash storage devices – CF2SCSI.
Inside the plastic casing is a small printed circuit board, which has some power circuitry and a small number of surface-mounted integrated circuits (ICs).[citation needed] Typically, one of these ICs provides an interface between the USB connector and the onboard memory, while the other is the flash memory. Drives typically use the USB mass storage device class to communicate with the host.[28]

In the arcade game In the Groove and more commonly In The Groove 2, flash drives are used to transfer high scores, screenshots, dance edits, and combos throughout sessions. As of software revision 21 (R21), players can also store custom songs and play them on any machine on which this feature is enabled. While use of flash drives is common, the drive must be Linux compatible.

This drive’s small size won over our testers: “Its small profile allows it to stay plugged into a computer even when transporting it in a bag or case, which is not something most flash drives can claim,” one person said. Lifewire reviewers agree that the drive’s tiny footprint makes it much more likely to get lost, but they say its fast read speeds and convenient portability easily make up for that.
These products use flash memory chips, a stable, high-density storage medium, to hold your data. They pack a huge amount of information into a compact form factor. Most thumb drives are less than 2 inches long and easily fit in a pocket, laptop bag or purse. Models with built-in covers protect physical connectors from damage, and select products feature rugged silicon and metal shells that enhance heat and water resistance.
