A logical block management method for managing a plurality of logical blocks of a flash memory device is provided. The logical block management method includes providing a flash memory controller, grouping the logical blocks into a plurality of logical zones, wherein each logical block maps to one of the logical zones. The logical block management method also includes counting a use count value for each logical block, and dynamically adjusting mapping relations between the logical blocks and the logical zones according to the use count values. Accordingly, the logical block management method can effectively utilizing the logical zones to determine usage patterns of the logical blocks and use different mechanisms to write data, so as to increase the performance of the flash memory storage device. |
