  • Patent number: 11360714
    Abstract: Embodiments of this application disclose example methods for processing data blocks and controllers. One example method includes configuring, by a controller, a counter of a global write stamp where the global write stamp is used to represent a total quantity of times that the controller performs writing on a storage medium. When a write operation is performed on a physical data block in the storage medium, a global write stamp can be used at a current moment as an instant write stamp of the physical data block, and the instant write stamp can be stored. Physical data blocks can be inspected periodically. When the physical data block is inspected, a determination as to whether the physical data block is a to-be-moved data block can be made based on the stored instant write stamp.
