摘要: A method and system are provided for improving the speed writing data in a disk array (RAID). Sectors of disks divided into ones reading old other new data. An external semiconductor storage device is used as parity which significantly enhances performance writing. Preferably, storing group comprises N units stored sectors magnetic drives with device. At least N+1 provided, where at one drive redundant sectors.
