Abstract

A storage system comprises a first controller and a plurality of storage devices. The Plurality of storage devices configure RAID each of which includes one or more non volatile memory chips providing storage space where data from a host computer is stored and a second controller coupled to the non volatile memory chips. In case where the first controller receives an update request to update first data to second data from the host computer the second controller in a first storage device of the storage devices is configured to store the second data in an area different from an area where the first data has been stored in the storage space of the first storage device; generate information that relates the first data and the second data; and generate an intermediate parity based on the first and the second data. The second controller in a second storage device of the storage devices that stores a first parity corresponding to the first data is configured to receive the intermediate parity generate a second parity based on the first parity and the intermediate parity and store the second parity in an area in the storage space of the second storage device. The second controller in the first storage device is configured to delete the information after the second parity is stored in the area in the storage space of the second storage device and set the area where the first data has been stored as a erase target area.
