A data writing method for writing data from a host system into a flash memory chip is provided. The method includes configuring a plurality of logical page addresses, grouping the logical page addresses into a plurality of logical blocks, and recording the data dispersion degree of each of the logical blocks. The method also includes receiving write-in data from the host system, identifying a logical block that a logical page address to be written by the host system belongs to, and writing the write-in data into the flash memory chip according to the data dispersion degree of the logical block, wherein the data dispersion degree of each of the logical blocks is not larger than a logical block data dispersion degree threshold value. Accordingly, the method can effectively reduce the time for executing a host write command. |
