Abstract
The invention discloses a data storage system and a control method thereof. The data storage system according to the invention includes N groups of storage devices, where N is an integer larger than 1. The invention is to judge if the use information of one of the batches of data satisfies the set of condition thresholds relative to the group of storage devices where said one batch of data is stored, and if NO, to re-allocate said one batch of data to one of the group of storage devices whose condition thresholds are satisfied by the use information of said one batch of data and to update the virtual drive locations of said one batch of data mapping the logical locations of the storage devices.
