Zusammenfassung:	A method for computing and storing parity information in a RAID system includes dividing each segment in a stripe into a data block and a parity block, and storing in each parity block, parity information for a limited number of other data blocks in the stripe. A method for rebuilding data in a RAID system includes rebuilding the data from parity information and storing the rebuilt data on reserve portions of the remaining disks in the system.
