摘要：
A reading/writing process control unit for instructing a reading/writing process and an erasing process control unit for instructing an erasing process are provided separately and each is connected with two HDDs via a switch. While the reading/writing process control unit is connected with one HDD and executing a reading/writing process, a switch is controlled to connect the erasing process control unit with another HDD to erase data of the HDD connected with the erasing process control unit. Since it is enabled to execute a data reading/writing process and a data erasing process for a storage device in parallel for different HDDs, lowering of the access rate as a whole can be prevented.
