raid - Computer Definition
A storage technology that distributes data across a group of physically separate hard drives configured as a single logical memory unit. As RAID stores all data on redundant drives, it provides a considerable level of fault tolerance. RAID may involve drives on multiple servers in a cluster connected via a storage area network (SAN). A simpler and less expensive approach is known as just a bunch of disks (JBOD), which essentially is a bunch of disk drivers not configured as a RAID. See also JBOD, SAN, and server.
(Redundant Array of Independent Disks) A disk subsystem that increases performance or provides fault tolerance or both. RAID uses two or more physical disk drives and a RAID controller, which is plugged into motherboards that do not have RAID circuits. Today, most motherboards have built-in RAID but not necessarily every RAID configuration (see below). In the past, RAID was also accomplished by software only but was much slower. In the late 1980s, the "I" in RAID stood for "inexpensive" but was later changed to "independent." In large storage area networks (SANs), floor-standing RAID units are common with terabytes of storage and huge amounts of cache memory. RAID is also used in desktop computers by gamers for speed and by business users for reliability. Following are the various RAID configurations. See NAS and SAN.
