Hard disk read-write rate reduction solving system and server

Abstract

The invention discloses a hard disk read-write rate reduction solving system. Sound-absorbing cotton is arranged at one or more positions of an inner surface of a case upper cover, an inner surface of a bottom plate, a fan wall, a hard disk backboard bracket and the fan wall between a hard disk and a fan, and the surface of the sound-absorbing cotton is parallel to the direction of airflow, so that normal flowing of the airflow is not influenced; noise is a main reason influencing the reduction of the read-write performance of the hard disk, the sound-absorbing cotton is a porous sound-absorbing foam material, a large number of pores are formed in the sound-absorbing cotton, the pores are communicated with one another, and after sound waves enter the surface of the sound-absorbing cotton, a part of the sound waves are reflected by the sound-absorbing cotton, and a part of the sound waves are transmitted into the sound-absorbing cotton; air vibration caused by the sound waves entering the sound absorption cotton can convert a part of sound energy into heat energy due to friction and viscous resistance between air and pores, most of the sound energy can be consumed and absorbed by the porous sound absorption material, the influence on the hard disk is reduced in a noise reduction mode, and the problem that the read-write rate of the hard disk is reduced is solved.

Description

technical field [0001] The present invention relates to the technical field of hard disks, and further relates to a solution system for reducing the reading and writing speed of hard disks. In addition, the present invention also relates to a server. Background technique [0002] To solve the heat dissipation problem of the server, increasing the fan speed inside the system is a more economical choice. However, due to the complex internal structure of the common mechanical hard disk, it is very easy to be interfered by the outside world (such as a fan), which leads to the problem that the data read and write rate of the hard disk is reduced, which is called the hard disk RV problem here. Normally, the higher the fan speed, the more the data read and write degradation rate of the hard disk, but due to resonance, there will be some special cases, for example, when the fan speed is 80% duty, the hard disk degradation rate is the most. In recent years, with the continuous incr...

AI Technical Summary

Problems solved by technology

Due to the ultra-high speed of the mechanical hard disk, when the hard disk reads or writes data, it is very sensitive to shaking and bumping, and is easily affected by the outside world. When the hard disk is disturbed by the outside world (mainly the fan in the server), the disc When rotating to the corresponding sector, the magnetic head is easily out of the correct track, which will greatly increase the time required for data reading and writing
