  • RAID 1 consists of an exact copy (or mirror) of a set of data on two or more disks; a classic RAID 1 mirrored pair contains two disks.


  • RAID 5 consists of block-level striping with distributed parity. It requires that all drives but one be present to operate.
  • Upon failure of a single drive, subsequent reads can be calculated from the distributed parity such that no data is lost.
  • RAID 5 requires at least three disks.

RAID 5 + Hotspare

  • RAID 5+Spare is a RAID 5 array in which one disk is used as spare to rebuild the system as soon as a disk fails.
  • At least four disks are required.
