Abstract
A management method for a data storage device is provided and includes the following steps: obtaining a plurality of association rules according to a plurality of previous access commands; building a plurality of look-up tables according to the association rules; receiving a current access command and determining whether the current access command corresponds to at least one of the look-up tables to obtain physical addresses of the current access command from the corresponding look-up table; predicting a look-up table corresponding to a subsequent access command based on these association rules; and pre-establishing the predicted look-up tables. The invention also provides a data storage system and a data storage device, which can implement the management method described above.
