solid state drive (ssd)

A SSD is a data storage device that uses solid-state memory to store persistent data. An SSD drive, unlike a traditional hard disk drive, does not have spinning disks or moveable read/write heads. Solid State Drives use microchips that have no moving parts. As of 2010, most Solid State Drives use NAND-based flash memory, which can retain memory without the need for power.
