In 1987, three researchers at the University of California Berkeley, published a paper called 'A Case for Redundant Arrays of Inexpensive (Independent has replaced Inexpensive) Disks (RAID).' It described various types of disk arrays, referred to by the acronym RAID. The basic idea of RAID combined multiple small, inexpensive disk drives into an array of disk drives, which yields performance exceeding that of a single large expensive drive. Additionally, this array of drives appears to the computer as a single logical storage unit or drive.
