The present disclosure provides a method and apparatus for a redundant array of independent disks, RAID. The method includes: dividing the RAID into a plurality of sub-RAIDs; generating sub-RAID metadata corresponding to each of the sub-RAIDs; and in response to a disk in the RAID being replaced, rebuilding data in a corresponding sub-RAID based on the sub-RAID metadata. The present disclosure further provides a computer readable storage medium and a storage system.
