| 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 . |
