초록
In this paper, we study a pattern-aware write cache policy using a NAND flash memory in disk-based mobile storage systems. Our work is designed to face a mix of a number of sequential accesses and fewer non-sequential ones in mobile storage systems by redirecting the latter to a NAND flash memory and the former to a disk. Experimental results show that our policy improves the overall I/O performance by reducing the overhead significantly from a non-volatile cache over a traditional one.
