Answer:SSM-redundant array of inexpensive/independent disks (RAID)

Explanation:RAID (Redundant Array of Inexpensive Disks or Drives, or Redundant Array of Independent Disks) is a data storage virtualization technology that combines multiple physical disk drive components into one or more logical units for the purposes of data redundancy, performance improvement, or both.

Redundant array of independent disks (RAID) is a method of storing duplicate data on two or more hard drives. It is used for data backup, fault tolerance, to improve throughput, increase storage functions and to enhance performance ... The OS sees RAID as a single logical hard drive called a RAID array.
