摘要： A storage system includes a plurality of disk apparatuses configuring a plurality of RAID groups, a spare disk apparatus, and a controller. The controller is adapted to copy data stored in a disk apparatus, whose error count exceeds a first threshold, to the spare disk apparatus. If an error count of a disk apparatus included in a RAID group exceeds a second threshold which is lower than the first threshold, the controller is adapted to check error counts of other disk apparatuses included in the same RAID group. If any of the error counts of the other disk apparatuses included in the same RAID group exceeds the second threshold, the controller is adapted to change the first value of the first disk apparatus and the other disk apparatuses included in the same RAID group.
