Flash memory SSDs pose a well-known challenge, that is, the erase-before-write problem. Researchers try to solve this inherent problem from two different angles by either designing sophisticated Flash Translation Layer (FTL) schemes to postpone and minimize erasures or designing flash-aware buffer management algorithms to absorb unnecessary erasures. Our experimental results show that buffer management inside SSD is necessary and indispensable. Further, based on our observation that TPC and… CONTINUE READING
