Most existing flash-aware caching algorithms focus on the asymmetry of read/write operations while we address the discrepancy of the asymmetry for different flash-based SSDs. We propose a low-overhead caching algorithm LOCA, which considers the frequency of pages and the discrepancy of the asymmetry for different SSDs. When selecting a victim page, LOCA chooses a low overhead victim page according to the ratio of read/write cost and the ratio of dirty pages to clean pages. The experiments show that LOCA works well for different kinds of SSDs and workloads.
