Step S102, determining a target transmission speed corresponding to the actual environment parameter in a preset environment speed corresponding relation;
in this step, the preset environment speed corresponding relationship includes a corresponding relationship between a plurality of pairs of environment parameters and the transmission speed, so that the environment parameter identical to the actual environment parameter can be found in the environment speed corresponding relationship, and the transmission speed corresponding to the environment parameter is determined as the target transmission speed.

Step S203, respectively performing data operation on data in an idle storage area in the NAND flash memory under a plurality of preset environment parameters, and determining actual use parameters corresponding to different preset environment parameters;
step S204, aiming at each preset environment parameter, comparing the optimal use parameter corresponding to the preset environment parameter with the actual use parameter to obtain a comparison result;
in this step, the optimal usage parameter and the actual usage parameter may be subtracted, and if the difference between the optimal usage parameter and the actual usage parameter is a positive number, the comparison result is determined to be that the optimal usage parameter is greater than the actual usage parameter;
and if the difference between the two is negative, determining that the comparison result is that the optimal use parameter is smaller than the actual use parameter.
Step S205, adjusting the data transmission speed according to the comparison result;
