In particular the hard-disk access time can be the key factor capping cache performances. In this paper, we present a new cache replacement policy that takes advantage of a hierarchical caching architecture, and in particular of access-time difference between memory and disk. Our policy is optimal when requests follow the independent reference model, and significantly reduces the hard-disk load, as shown also by our realistic, trace-driven evaluation.
