In a data prefetching method, a storage device obtains a first sequence stream length and a first access count of a target logical block after execution of a first data access request is completed. When a second data access request is received, the storage device modifies the first sequence stream length to a second sequence stream length and modifies the first access count to a second access count. The storage device further calculates a sequence degree of the target logical block based on the second sequence stream length and the second access count, and performs a data prefetching operation when the sequence degree of the target logical block exceeds a first prefetch threshold.
