USB Drives

USB drives mean Universal Serial Bus. USB flash drives also known as USB drives, key drives, pen drives or thumb drives. USB drives are NAND-type flash memory data storage devices incorporated with a USB interface. They are typically small, lightweight, detachable and rewritable. As of April 2007, memory capacities for USB Flash Drives currently are sold from 32 megabytes up to 64 gigabytes .Capacity is limited only by current flash memory densities, although cost per megabyte may increase quickly at higher capacities due to the expensive components.

USB flash drives offer possible advantages over other portable storage devices, particularly the floppy disk. They are more compact, generally faster, hold more data, and are more consistent than floppy disks. These types of drives use the USB mass storage standard, supported natively by recent operating systems such as Linux, Mac OS X, UNIX, and Windows.
