Claim 12:
13. The apparatus of claim 12, wherein the program instructions further cause the apparatus to be configured to:
progressively increase a heat count of the first fingerprint based on a quantity of times of reading the first data block;
for a second fingerprint whose heat count is greater than a first threshold within a preset time, migrate the second data block that corresponds to the second fingerprint from the low-speed storage medium to the high-speed storage medium to obtain a first migrated data block when a storage address of the second data block that corresponds to the second fingerprint is the low-speed storage medium; and
modify an address that corresponds to the second fingerprint of the first migrated data block in the fingerprint list to the address of the data block in the high-speed storage medium.
