Abstract:
A data storage method includes: separately dividing a data block and a reference data block into N equal-sized sub-data blocks, comparing a sub-data block and a reference sub-data block corresponding to a same location identifier, determining, in the N sub-data blocks, a sub-data block that can be deduplicated and a sub-data block that cannot be deduplicated, performing a deduplication operation on the sub-data block that can be deduplicated, selecting a representative sub-data block of the sub-data block that cannot be deduplicated, performing an exclusive OR operation on data of the sub-data block that cannot be deduplicated and data of the representative sub-data block, compressing a result of the exclusive OR operation using run-length encoding, and storing a compression result and location information of the sub-data block that cannot be deduplicated.

Claim (Index 17):
The storage apparatus according to  claim 10 , before dividing the data block into N equal-sized sub-data blocks, the processor is further configured to:\n extract a sample from data to be stored; separately determine a storage compression ratio, a storage speed, and a read speed of the sample according to different sub-data block sizes; and determine a value of N according to a size of a sub-data block with a smallest storage compression ratio if the storage speed and the read speed satisfy a constraint condition, wherein the constraint condition is that the storage speed is greater than or equal to a first preset threshold, and the read speed is greater than or equal to a second preset threshold.
