High Quality Content by WIKIPEDIA articles! The standard RAID levels are a basic set of RAID configurations and employ striping, mirroring, or parity. The standard RAID levels can be modified for other benefits (see Nested RAID levels for modes like 1+0 or 0+1). Other, non-standard RAID levels and non-RAID drive architectures provide alternatives to RAID architectures. RAID levels and their associated data formats are standardized by SNIP in the Common RAID Disk Drive Format (DEF) standard.
