Abstract: A host of a storage system is coupled to multiple SSDs. Each SSD is configured with a migration cache, and each SSD corresponds to one piece of access information. The host obtains migration data information of to-be-migrated data in a source SSD, determines a target SSD, and sends a read instruction carrying information about to-be-migrated data and the target SSD to the source SSD. The source SSD reads a data block according to the read instruction from a flash memory of the source SSD into a migration cache of the target SSD. After a read instruction is completed by the SSD, the host sends a write instruction to the target SSD to instruct the target SSD to write the data block in the cache of the target SSD to a flash memory of the target SSD.
