Описание тега usb-flash-drive
A USB flash drive is a data storage device that includes flash memory with an integrated Universal Serial Bus (USB) interface.
USB flash drives are typically removable and rewritable, and physically much smaller than a floppy disk. USB flash drives are often used for the same purposes for which floppy disks or CD-ROMs were used, i.e., for storage, back-up and transfer of computer files. They are smaller, faster, have thousands of times more capacity, and are more durable and reliable because they have no moving parts. wikipedia
