Abstract
A hard disk includes a storage medium, an interface, and a processor. The storage medium is configured to provide a storage space including a plurality of logical units. Each logical unit internally stores data in an append-only write manner, a storage space corresponding to each logical unit comes from one or more erase blocks in the hard disk, and the erase block is a minimum erase unit of the hard disk. The interface is configured to provide a controller with a logical unit identifier, and receive a data access request that includes the logical unit identifier and that is sent by the controller. The processor is configured to search for a to-be-accessed storage space based on the logical unit identifier in the data access request.
