1. A data migration method comprising:
receiving, from a host, a data migration instruction comprising migration data information of to-be-migrated data stored in a source solid-state disk (SSD) cache of a source SSD coupled to the host; and
reading, in response to the data migration instruction, a to-be-migrated data block within the to-be-migrated data from the source SSD cache into a target SSD cache of a target SSD coupled to the host.
