Does a USB flash drive use much power?

The power consumption of a typical flash drive is very low, much lower than that of the common alternative, the portable hard disk, due to there being no moving parts inside a flash drive. Portable hard disks, on the other hand, require several motors or actuators to rotate the disk platter, and move the read / write head. Consequently, the USB flash drive need not be as big, or heavy, allowing greater portability.
