Summary:PURPOSE: A differential caching mechanism based on media i/o speed is provided to increase the hit rate of storage units by efficiently assigning cache. CONSTITUTION: A cache entry related to high-speed response storage units and cache entry related to slow response storage units are saved in the read cache(316). An extracting method is prepared in the read cache. The extracting method downward controls the cache entries of fast response storage devices. The high and low read hit ratio is calculated by the read hit times through the interval.
