Abstract:
To provide a storage control device capable of changing the rotation speed of storage devices.A plurality of hard disk drives 1 is mounted in the device mounting unit 7. The rotation speed control unit 2 detects the mounting location of each hard disk drive 1, and determines the rotation speed in accordance with the location of each hard disk drive 1. The rotation speeds of adjacent hard disk drives 1 are different from each other. The rotation speed control unit 2 changes the rotation speed of each hard disk drive 1 to the determined rotation speed.
