1. A data management method for a solid state storage device, the solid state storage device comprising a non-volatile memory, the data management method comprising steps of:
calculating a first average write speed in an (N−2)-th time interval, wherein N is a positive integer;
calculating a second average write speed in an (N−1)-th time interval, wherein after the second average write speed is subtracted from the first average write speed, an average write speed difference is obtained;
if the average write speed difference is lower than a threshold write speed, disabling a time axis compensator write operation in an N-th time interval;
monitoring an instant write speed;
if the average write speed difference is higher than the threshold write speed and the instant write speed is higher than the average write speed difference, disabling the time axis compensator write operation in the N-th time interval; and
if the average write speed difference is higher than the threshold write speed and the instant write speed is lower than the average write speed difference, enabling the time axis compensator write operation in the N-th time interval.
