The disclosure relates to a cache management method for a post-store cache. Recently referenced units of storage in the cache are identified and a round robin cache replacement method is generally used to select a unit of storage for replacement if the unit of storage has not been recently referenced. Recently used segments are identified by maintaining a Recently Used Zone ahead of the storage location presently considered for replacement. For each reference to a unit of storage in the cache which results in a miss, a portion of the cache is scanned for units of storage to destage.
