Abstract
NAND Flash-based SSD has gained prevalence in enterprise and embedded system as storage device because its high I/O performance, low-power consumption, and Anti-vibration characteristics. RAID consisting of SSD can achieve higher performance. However, it brings new problems such as parity disks suffering from premature aging, data disk aging simultaneously. This paper based on the variation of SSDs reliability, design a new RAID-5 architecture with dynamic stripe length. It can effectively reduce the disk space overhead and improve the safety performance of the RAID.
