mass storage - Computer Definition
Permanent peripheral storage, which is typically a hard disk drive, solid state drive (SSD) or USB drive. "Mass" is an old term that refers to large amounts of permanent storage in contrast with the smaller amount of "RAM" or "main memory," which is the computer's temporary workspace (see memory). See flash memory, USB drive, magnetic disk, optical disc and magnetic tape.
