Zusammenfassung:PROBLEM TO BE SOLVED: To provide a disk array system which increases the number of data transferable in parallel. SOLUTION: At a drive unit 3 connected to a disk control unit 2 of the disk array system, a logic group 5 consisted of a plurality of drives 4 is constituted, in this logic group 5 each data is duplicated and stored so that copied data of a plurality of data stored in same drive are stored each other in different another drives except the drive, and when a plurality of data stored in the same drive are read out, the duplicated data or the original data are read out from the different drives in parallel.
