Layered ssd/hddhybridstoragesystem has been widely used. However, most traditional designs are performance oriented, and not optimized for ssdlifespan. In this paper, ssdlifespanoriented layered model and cache algorithm are proposed. To decrease ssd wear rate, hdd-RAM switch tunnel is appended to the traditional layered hybrid structure. cache window size is considered in cache algorithm to filter data, avoiding unnecessary cache cost. Results show optimized designs significantly reduced erase times on ssd, and slightly influenced original performance.
