SSD (Solid State Drive)
A Solid State Drive is a drive that can be installed like any other drive; it does not contain a
rotating disk or other moving parts because only semiconductor memory chips of similar
capacity will be used. This design makes SSDs more rugged, provides shorter access times,
low energy consumption and rapid data transfer.
