Claim 3:
4. The data storage method of claim 1, further comprising:
progressively increasing 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, migrating a second data block corresponding to the second fingerprint from the low-speed storage medium to the high-speed storage medium to obtain a migrated data block when a storage address of the second data block corresponding to the second fingerprint is the low-speed storage medium; and
modifying an address corresponding to the second fingerprint of the migrated data block in the fingerprint list to the address of the second data block in the high-speed storage medium.
