    Actually, ANY drive - powered or unpowered, flash, jump or desk type - is a USB drive IF you connect it to a USB (Universal Serial Bus) computer port for data transfer (moving information to/from the computer).

    While the USB port DOES provide electrical power, and some drives/devices CAN get all the power they need from the port, that's NOT a requirement.

    A jump drive - also known as a USB drive, flash drive, keychain drive, or disk-on-key - is a plug-and-play portable storage device that uses flash memory and is lightweight enough to attach to a key chain. A jump drive, which looks very much like an ordinary highlighter marker pen, can be used in place of a floppy disk, Zip drive disk, or CD. When the user plugs the device into their USB port, the computer's operating system recognizes the device as a removable drive and assigns it a drive letter. Unlike most removable drives, a jump drive does not require rebooting after it's attached, does not require batteries or an external power supply, and is not platform dependent. Several jump drive manufacturers offer additional features such as password protection, and downloadable drivers that allow the keychain drive to be compatible with older systems that do not have USB ports. Jump drives are available in capacities ranging from 8 MB to 2 gigabytes, depending on manufacturer, in a corresponding range of prices.

    With a jump drive, data can be retained for long periods when the jump drive is removed from the computer, or when the computer is powered-down with the drive left in. This makes the jump drive convenient for transferring data between a desktop computer and a notebook computer, or for short-term backup of small to moderate quantities of data.

    USB flash drives are NAND-type flash memory data storage devices integrated with a USB interface. They are typically small, lightweight, removable and rewritable. Memory capacity typically ranges from 64 megabytes up to 8 gigabytes [1], limited only by current flash memory densities. As capacity increases, so does price.
