A machine-implemented method, which is for categorizing a plurality of to-be-categorized storage units of a storage medium, includes: a) using a processor to write categorizing data for filling each of the to-be-categorized storage units of the storage medium; b) using a processor to determine a data access time of each of at least some of the to-be-categorized storage units by reading the categorizing data therein and to record the data access times of said at least some of the to-be-categorized storage units; and c) using a processor to categorize the to-be-categorized storage units into a plurality of groups that respectively correspond to a plurality of data access speed categories with reference to the recorded data access times.
