The standard RAID levels comprise a basic set of RAID (redundant array of independent disks) configurations that employ the techniques of striping, mirroring, or parity to create large reliable data stores from multiple general-purpose computer hard disk drives (HDDs).
- RAID 0: Stripping
- RAID 1: Mirroring
- RAID 2: Hamming code for error detection
- RAID 3: Byte-level striping with a dedicated parity disk
- RAID 4: Block-level striping with block-level striping with two parity blocks parity
- RAID 5: Block-level striping with distributed parity
- RAID 6: Block-level striping with double distributed parity.
