(2) A magnetic disk drive that plugs into a USB, FireWire or eSATA port on a computer. Used for backup, secondary storage as well as transport, portable hard drives rival the capacity of many internal hard drives.

Portable Vs. Desktop Drives
External drives for stationary desktop use are larger than the portable drives used for transport. In addition, USB desktop drives typically require power from the wall, whereas portable hard drives can be powered from the USB connection. See USB drive kit and SATA.
