In cloud and game servers, SSDs are used as cache on large capacity disk-based storage. In thatconfiguration, the SSD can be exploited as write-back or write-through cache. Though the write-backcache can improve write performance significantly, data can be lost when the SSD fails. On the contrary,performance improvement is limited in the write-through cache though it has high reliability. By the way,reliability can be improved by applying RAID technique to SSD cache while exploiting write-back forbetter performance. In this paper, we analyse the reliability and the performance of hybrid storage usingSSD cache over disk-based primary storage. In particular, we mathematically analyse reliability and alsomeasure performance of real storage systems with various SSD cache configurations.
