This page refers to removable USB flash drives, not to be confused with SATA/PATA Solid-state drives

A Flash Memory Drive (a.k.a Thumb Drive, Memory Stick, Jump Drive, and Flash Drive) is a kind of digital data storage device which uses flash memory to store all manner of files and information. Flash memory is an efficient, non-volatile type of storage which is composed of MOSFET's that have a special "floating gate", so well insulated that it can hold its charge, thereby controlling the transistor, indefinitely. The charge in the floating gate can be set using electrical impulses. When disconnected from power, the transistors hold their charge, so data can be stored for quite some time and/or transferred to another device. As flash memory develops, flash memory drives become progressively less expensive while capacity continues to increase. These removable drives are generally connected to devices using Universal Serial Bus (USB) connections.
