A USB flash drive is a compact, portable device that plugs into any standard USB port. USB is short for universal serial bus, and this device is used to store and transfer data. A USB flash drive allows users to easily transfer information between multiple devices and computers.
USB flash drives generally vary in shape, size and color. Some devices can store gigabytes of information and can function as portable hard drives. These drives are easy to use and small enough to transport in a pocket. Although most USB flash drives offer a smaller storage capacity than hard drives, these devices are more durable and do not contain internal moving components.
