Abstract: With the introduction of the novel solid-state storage technology and the hybrid cache architecture using DRAM and solid state drive (SSD), this paper presents a kind of two-level cache for mass storage system strategy, which effectively reduces SSD caching lowercase problem by write-back strategy, and the logical disk created by two-level cache architecture is tested. The results show that the average response time of the request is optimized.
