Description
Technical Field
The field relates to the field of computers, and more particularly to a method, apparatus, device and readable medium for evaluating the performance of a hard disk in a noisy environment.
Background
Mechanical hard disks are used as high-speed mass storage devices and are widely applied to various servers, data centers and other devices. Meanwhile, due to the heat dissipation challenge brought by high power consumption, various high-speed fans are widely applied, so that the hard disk is in a high-noise environment for a long time. Experimental data show that high noise greatly affects the read-write performance of the mechanical hard disk, and even in a fixed device, the noise becomes one of the most important factors affecting the read-write performance and the service life of the mechanical hard disk. However, in recent years, as the mechanical hard disk is more precise and the magnetic track is narrower, the influence of noise on the read-write performance of the hard disk is more obvious, and the influence of noise on the performance of the hard disk is increasingly prominent in recent years and becomes one of the main problems that the design and the use of the current mechanical hard disk cannot be avoided. Meanwhile, the research on the technology of the correlation between the noise and the performance of the hard disk is just started, and the research on the correlation between the noise and the performance of the hard disk is not carried out.

However, the implementation of such simple noise reduction often requires a large increase in manufacturing and installation costs, and also causes a great waste of resources.
