A solid-state drive (SSD) is a solid-state storage device. It provides persistent data storage using no moving parts. It is sometimes called semiconductor storage device or solid-state device. It is also called solid-state disk because it is frequently interfaced to a host system in the same manner as a hard disk drive (HDD).[1][2]
