The Free On-line Dictionary of Computing (30 December 2018):

data storage
storage

    (Or "memory") A device or medium into which data can
   be entered, in which it can be held, and from which it can be
   retrieved at a later time.

   The distinguishing characteristics of a device are its
   capacity (the number of bytes it can hold), its access
   speed, whether it is volatile (loses data when the power is
   turned off), whether it is removeable or fixed and whether
   it is writeable or read-only.

   Some examples are DRAM, hard disk, CD-ROM, Flash
   memory.
