Abstract: There are a lot of issues of the SSD arising in the storage industry. This paper proposed a caching FTL design to improve the efficiency of the SSl)random write and reduce the amount of erasure operations by on-chip SRAM. By simulation experiments of SSDsim,we demonstrated the efficiency of our design. At the end of this paper,I gave my follow-up plan in this work.

Key words: Solid-state drive,曰'I，Erasure operations, Random writes
