Abstract: Embodiments of the present disclosure provide a data processing method, a controller, a storage device, and a storage system. The controller adds an execution time of an IO request to the IO request, and the execution time is used to instruct the storage device to complete the IO request before the execution time expires. The controller sends, to the storage device, the IO request to which the execution time is added. When receiving the IO request, the storage device can execute the IO request based on the execution time of the IO request.
