摘要： PROBLEM TO BE SOLVED: To improve the performance of read processing, without pressing the disk capacity, and moreover, by using simple processings. SOLUTION: When a read command generation section 315a analyzes a read request, and if two or more read requests which acquire data from the same hard disk device continue, a read command which acquires data by an exclusive OR operation, and a read command which acquires data as the specification of the read request are generated by turns. When read requests which acquire all the data stored in stripes of a specific range continue, the read command is generated so that the frequencies of access to hard disk devices 11-14 become equal, and the frequency of continuous access becomes larger.
