    • There are provided a plurality of physical disks and a controller for performing reading and writing of data to the storage areas of the physical disks according to instructions from a host device. In each physical disk, the storage area is divided into a number of areas, and a divided storage area of one physical disk is set to make a pair with a divided storage area of another physical disk. Data is managed by using divided storage areas of different physical disks set to be in a pair, whereby improvement in reliability, cost reduction and miniaturization can be achieved.
    • 提供了多个物理磁盘和控制器,用于根据来自主机设备的指令执行数据到物理磁盘的存储区域的读取和写入。 在每个物理磁盘中,将存储区域划分为多个区域,并且将一个物理磁盘的划分的存储区域设置为与另一个物理磁盘的划分的存储区域成对。 通过使用不同物理磁盘的分割存储区域进行数据管理,可以实现可靠性,成本降低和小型化的提高。
