RAID (Redundant Array of Independent / Inexpensive Disks)
A disk array in which part of the storage capacity is used to store redundant information about
user data stored on the remainder of the storage capacity. The redundant information enables
regeneration of user data in the event that one of the array member disks or the access path to
it fails. See Parity. Different RAID levels offer different data throughput speeds and fault
tolerance (data redundancy). RAID 0 does not feature redundant information but is nonetheless
considered a special type of RAID.
