摘要：
A disk array device includes, a cache memory, a plurality of types of disk drives of which data transfer capacity are different, redundant transmission paths that are data transfer paths between the cache memory and the disk drives, and a controller to divide the disk drives into two groups based on the data transfer capacity and allocate each of the two groups to each of the redundant transmission paths when the disk drives have three types.
