Zusammenfassung:	PURPOSE: A device and a method for forming a memory of an RAID(Redundant Array with Inexpensive Disks) storage system equipped with a virtual RAID controller and a separate memory are provided to judge an optimal I/O(Input/Output) configuration together with operation of the virtual RAID controller by testing performance features of multiple I/O operations. CONSTITUTION: A SAN(Storage Area Network)(102) is equipped with a switch(106) including a storage equipment(1062). The storage equipment includes the memory(106 22), a stripe size attribute(10624), and a stripe arrangement attribute(10626). The SAN connects to a host(104) to the RAID storage system(108) including the RAID controller(1082) and a memory device array(1084). The RAID controller uses striping in order to distribute data across the memory device array, and stores parity information for the data stored in the memory device array.
