Mondo Knows Facts

RAID was named in a 1988 Berkeley paper

Three researchers described ways to combine cheap disks so one could fail without losing the data David Patterson, Garth Gibson and Randy Katz published the paper at the University of California, Berkeley, and admitted the redundant array of inexpensive disks acronym was partly chosen to sell the idea. Their levels mirrored data, striped it across drives or stored parity, so a dead disk could be rebuilt. Parity costs one disk per set and slows small writes. It sits in Mondo's technology collection, one of 200 facts that each trace back to the reference below.
