When storing write data to multiple discontinuous areas within stripes of a storage device, the storage system transmits a new data transmission command containing information for specifying the multiple discontinuous areas and a write data to the storage device, and thereafter, receives an intermediate parity generated from multiple write data and data before update of the multiple write data from the storage device, and then transmits the received intermediate parity and an intermediate parity transmission command to the storage device storing the parity. Thereafter, a data commitment command containing information for specifying multiple discontinuous areas is transmitted to multiple storage devices, and the storage device storing the parity generates a parity after update from the received intermediate parity and a parity before update corresponding to the intermediate parity, and stores the parity after update in a storage media."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Storage system","description":"The storage system according to the present invention comprises a controller, and multiple storage device constituting a RAID group.
