mass storage - technical definition
Permanent peripheral storage such as disks and tapes. Contrast with "temporary memory." The "mass" is used for emphasis, as "storage" is sufficient. At one time, it meant very large storage; however, the term is also used to refer to USB drives, which have very small capacities compared to disk. See magnetic disk, optical disc and magnetic tape.
