A storage controller system updating method includes: performing a system updating operation on a storage controller, and obtaining a real-time speed value and a real-time operation volume value that are generated when the system updating operation is performed on the storage controller; obtaining a corresponding speed reference value and operation volume reference value from a database based on device information of the storage controller; determining a volume corresponding to an operation volume abnormity based on a relationship between the real-time speed value and the speed reference value and a relationship between the real-time operation volume value and the operation volume reference value, and adjusting a volume parameter; and continuing to perform the system updating operation based on an adjusted volume parameter.
