Abstract: A solution for processing a stripe in a storage device is provided. Where at least one stripe unit not requiring garbage collection from each stripe of at least two stripes in the storage device is determined, each of the at least two stripes comprises a stripe unit requiring garbage collection and a stripe unit not requiring garbage collection; parity data of data in the determined stripe units not requiring garbage collection is computed and stored into a first idle stripe unit, where the first idle stripe unit and the determined stripe units not requiring garbage collection are in a new stripe in the storage device.
