N2 - The I/O performances of flash memory solid-state disks (SSDs) are increasing by exploiting parallel I/O architectures. However, the reliability problem is a critical issue in building a large-scale flash storage. We propose a novel Redundant Arrays of Inexpensive Disks (RAID) architecture which uses the delayed parity update and partial parity caching techniques for reliable and high-performance flash memory SSDs. The proposed techniques improve the performance of the RAID-5 SSD by 38% and 30% on average in comparison to the original RAID-5 technique and the previous delayed parity update technique, respectively.
