A storage system (1) of the present invention saves power consumption of the storage system and enhances responsiveness by predicting a disk drive (3) that is to be accessed next on the basis of an access request from a host system (2), and promptly feeding power to the predicted disk drive. A prediction unit (7) predicts the disk drive which is to be accessed next by the host system, by comparing a recent access request from the host system against a past access pattern that is registered in an access pattern record table (8). A power control unit (6) feeds power from a power unit to the disk drive predicted by the prediction unit. |
