Abstract

Storage drives of a plurality of types are mounted on a storage device together. A storage apparatus includes: an I/O controller that receives an access request sent from an information apparatus and writes data to or reads data from a storage drive; a storage drive mounting unit in which the storage drive is detachably mounted; a drive power supplying unit that supplies drive power to the storage drive mounted in the storage drive mounting unit; and a drive voltage identifying unit that identifies a voltage allowing data write to or data read from the storage drive mounted in the storage drive mounting unit, by raising a drive voltage applied to the storage drive from a voltage below a rated drive voltage of the storage drive. When the I/O controller writes data to or reads data from the storage drive, the drive power supplying unit applies the identified voltage to the storage drive to drive the storage drive.
