A USB drive — also known as a usb flash drive or keychain drive — is a plug and play portable storage device. It uses flash memory and is lightweight enough to attach to a key chain. It can be used in place of a floppy disk, Zip Drive disk, or CD. When the user plugs the device into the USB port, the computer’s operating system recognizes the device as a removable drive and assigns it a drive letter.
With a USB flash drive, data can be retained for long periods when the device is unplugged from the computer, or when the computer is powered-down with the drive left in. It is very convenient to transfer data with the use of USB. Their capacity ranges from 256MB, 1GB, 2GB and 4GB and there are many forms of USB flash drives available in the market.
They are more compact, generally faster, hold more data, and are more reliable (due to both their lack of moving parts, and their more durable design) than floppy disks. These types of drives use the USB mass storage standard, supported natively by modern operating systems such as Linux, Mac OS X, UNIX and Windows. Some of the cheap USB flash drives are: Imitation flash wristband, very stylish. Corsair flash voyager wraps their Flash Voyager, including the cap, with rubber. This makes the USB flash drive a true water-resistant portable storage. The 256MB flash drive with fingerprint authentication can encrypt up to 10 different thumbprints, 200 website logins and all the bookmarks.
Flash drive capacities on the market are continuously increasing. 64MB and smaller capacity flash memory has been largely discontinued and 128MB capacity flash memory is being phased out. The biggest trend that everyone’s looking forward to is USB 3.0.
