Abstract
A read unit 400 which governs reading of data and a write unit 500 which governs writing of data are located separately in a RAID unit 300 which controls array type magnetic disk units. To read data from magnetic disk units 800, a control circuit 600 uses the read unit 400 to read data through an HDD control unit 700. To write data, the control circuit 600 uses the write unit 500 to write data into the magnetic disk units 800. Since the read unit and write unit are provided separately, processing performance improves.
