RAID Definition

( Redundant Array of Independent Disks) A disk subsystem that is used to increase performance or provide fault tolerance or both. RAID uses two or more ordinary hard disks and a RAID disk controller. In the past, RAID has also been implemented via software only.

Small and Large Disk Striping Mirroring and Parity
RAID subsystems come in all sizes from desktop units to floor-standing models (see NAS and SAN ). Stand-alone units may include large amounts of cache as well as redundant power supplies. Initially used with servers, desktop PCs are increasingly being retrofitted by adding a RAID controller and extra IDE or SCSI disks. Newer motherboards often have RAID controllers.
RAID improves performance by disk striping, which interleaves bytes or groups of bytes across multiple drives, so more than one disk is reading and writing simultaneously.
Fault tolerance is achieved by mirroring or parity. Mirroring is 100% duplication of the data on two drives (RAID 1). Parity is used to calculate the data in two drives and store the results on a third (RAID 3 or 5). After a failed drive is replaced, the RAID controller automatically rebuilds the lost data from the other two. RAID systems may have a spare drive (hot spare) ready and waiting to be the replacement for a drive that fails.
RAID Levels
RAID 0 - Speed (Widely Used)
RAID level 0 is disk striping only, which interleaves data across multiple disks for performance. Widely used for gaming, RAID 0 has no safeguards against failure.

RAID 1 - Fault Tolerance (Widely Used)
Uses disk mirroring, which provides 100% duplication of data. Offers highest reliability, but doubles storage cost. RAID 1 is widely used in business applications.

RAID 2 - Speed
Instead of single bytes or groups of bytes (blocks), bits are interleaved (striped) across many disks. The Connection Machine used this technique, but this is rarely used because 39 disks are required.

RAID 3 - Speed and Fault Tolerance
Data are striped across three or more drives. Used to achieve the highest data transfer, because all drives operate in parallel. Using byte level striping, parity bits are stored on separate, dedicated drives. 		 

RAID 4 - Speed and Fault Tolerance
Similar to RAID 3, but uses block level striping. Not often used.

RAID 5 - Speed and Fault Tolerance (Widely Used)
Data are striped across three or more drives for performance, and parity bits are used for fault tolerance. The parity bits from two drives are stored on a third drive and are interspersed with user data. RAID 5 is widely used in servers.

RAID 6 - Speed and Fault Tolerance
Highest reliability because it can recover from a failure of two disks, but not widely used. Similar to RAID 5, but performs two different parity computations or the same computation on overlapping subsets of the data.

RAID 10, RAID 100 - Speed and Fault Tolerance
RAID 10 is RAID 1 + 0. The drives are striped for performance (RAID 0), and all striped drives are duplicated (RAID 1) for fault tolerance.
RAID 100 is RAID 10 + 0. It adds a layer of striping on top of two or more RAID 10 configurations for even more speed.
