摘要
A disk drive is disclosed that varies its caching policy for caching data in non-volatile solid-state memory as the memory degrades. As the non-volatile memory degrades, the caching policy can be varied such that the non-volatile memory is used more as a read cache and less as a write cache. Performance improvements and slower degradation of the non-volatile memory can thereby be attained.
