Hybrid write buffer algorithm for improving performance and endurance of nand flash storages

摘要

This paper proposes a novel buffering algorithm for write buffer, comprised of DRAM and NVM, in NAND flash storages of the home cloud server is proposed. As adopting dirty first migration and clean page caching technique, the algorithm may improve performances and lifetime of storage system of the home cloud server. The experimental results show that the algorithm improved buffer hit ratio by up to 116.51% and reduced the number of erase operations on NAND flash storage by up to 48.67%.
