RAID levels

A RAID level is any of the possible configurations of a RAID disk array. RAID stands for redundant array of independent disks (or, formerly, redundant array of inexpensive disks).

RAID levels may refer to:


 * Standard RAID levels, all the RAID configurations defined in the Common RAID Disk Drive Format standard, which is maintained by the Storage Networking Industry Association
 * Nested RAID levels, RAID configurations that incorporate features of two or more standard RAID levels
 * Non-standard RAID levels, variants of standard or nested RAID levels. Non-standard RAID levels deviate from the standard configurations defined by the Storage Networking Industry Association (SNIA).
