ABSTRACT:
A split parity spare disk achieving method for improving the defect endurance and performance of a RAID subsystem which distributively stores data in a disk array consisting of a plurality of disk drives and carries out an input/output operation in parallel includes the steps of: constructing the disk array with at least two data disk drives for storing data, a spare disk drive used when a disk drive fails and a parity disk drive for storing parity data; and splitting the parity data of the parity disk drive and storing the split data in the parity disk drive and the spare disk drive.
