RAID - Redundant Array of Independent Disks

RAID refers to a hard disk technology which can be used to speed up data transfer and/or provide disk redundancy through disk system fault tolerance. RAID provides these features by utilizing more than one hard disk at a time. There are several variations of a RAID configuration referred to as levels. Each of these levels provides different performance and/or fault tolerance benefits. RAID configurations are commonly found in data critical applications.

RAID 0 - Striped disk array
RAID 1 - Mirroring and duplexing
RAID 2 - Error-correcting coding
RAID 3 - Bit-interleaved parity
RAID 4 - Dedicated parity drive
RAID 5 - Block interleaved distributed parity
RAID 6 - Independent data disks with double parity
RAID 7 - Adds caching to levels 3 or 4
RAID 0+1/1+0 - High data transfer performance/ High reliability combined with high performance
RAID 50 - High I/O rates and data transfer performance
