PROBLEM TO BE SOLVED: To enhance performance, in a storage device including a plurality of clusters for controlling accesses to a hard disk drive, such as throughput between clusters with minimized cluster-to-cluster paths. SOLUTION: A plurality of clusters are mutually connected through two full-double communication paths. When a cluster 10A receives a read request from a host computer 2, and data shown by the read request are stored in the other cluster 10B, a processor part 6 of the cluster 10A selects, as a path to be used by a control system packet transmitted to the other cluster 10B, the same path as that used by a read data packet that is a data system packet transferred from the other cluster 10B to the cluster 10A.
