According to the method, the influence of the thread and the depth on the performance of the hard disk performance test is ensured to be matched with the parameters to reach the saturation point with the optimal hard disk performance, and the pressure of the disk is different due to the difference of different CPUs of different servers, so that the optimal parameters of the maximum capacity of the disk can be ensured to be exerted in each scene; aiming at different types of discs such as mechanical discs and solid state disks, the required preconditions are inconsistent, and in order to better enable the disc performance to tend to be stable, the characteristics of the solid state disks lead to the need of pre-embedding of data to be written; the difference between the random scene and the sequential scene of the mechanical disk and the solid state disk is that the sequential scene does not involve multithreading, and when the multithreading final performance adopted in the sequential scene tends to the performance in the random scene, the sequential thread is not used as a reference point and is mainly 1 thread according to the conventional default.
