Abstract: A storage controller and an operating method of the storage controller are provided. The storage controller includes processing circuitry configured to read sub-stripe data from each of a plurality of non-volatile memory devices connected with a RAID (Redundant Array of Inexpensive Disk), check error information of at least one of the sub-stripe data, and perform a RAID recovery operation in response to the at least one of the sub-stripe data having an uncorrectable error, and a RAID memory which stores calculation results of the RAID recovery operation.
