portable storage device

A system component that can be inserted into and removed from a system and that is used to store information or data (e.g., text, video, audio, and/or image data). Such components are typically implemented on magnetic, optical, or solid-state devices (e.g., compact/digital video disks, flash/thumb drives, external solid-state drives, external hard disk drives, flash memory cards/drives that contain nonvolatile memory).
