ABSTRACT:
A system is provided for improving the speed for writing data in a disk array system. The disk array system includes a solid state disk storage device configured with semiconductor flash memory to sequentially store the parity for the disk array. The solid state disk storage device allows data sectors to be assigned sequentially in a cluster consisting of a set of blocks. Each block is a physical unit of erasure. Write operations for a plurality of sectors are written across the set of blocks in the cluster.
