Abstract
A computer system using a processor with a multimedia functional unit capable of executing an Exclusive OR(XOR) type instruction for performing the RAID functions of storing and recovering bits on an array of disk drives. Blocks of data stored on different disk drives of the array are XORed together by the multimedia functional unit of a processor to form a parity block stored on a parity disk drive of the array. If one of the blocks is lost, the data can be recovered by the multimedia functional unit performing XOR instructions on the remaining data blocks and the parity block.
