Technical Field

Background

The hard disk is one of the main storage media of a computer and is composed of one or more aluminum or glass disks. The hard disk may be classified into a solid state disk (SSD disk, new hard disk), a mechanical hard disk (HDD, conventional hard disk), a hybrid hard disk (HHD, a new hard disk produced based on the conventional mechanical hard disk). SSD uses flash memory granules for storage, HDD uses magnetic discs for storage, and HHD is a hard disk that integrates a magnetic hard disk and flash memory together. With the rapid growth of cloud services and big data services, the mechanical hard disk is difficult to meet the requirement of a user for rapidly reading information in the hard disk, and the solid state hard disk is widely applied due to the fact that the solid state hard disk has the advantages of higher transmission speed and smaller size.

At present, a mechanical hard disk in a general server is fixed by directly placing the mechanical hard disk in an existing hard disk bracket, fixing the mechanical hard disk through 4 screws, and then pushing the mechanical hard disk into a case. However, since the speed of the mechanical hard disk is much lower than that of the solid state hard disk, when the mechanical hard disk needs to be replaced by the solid state hard disk to improve the reading speed of the hard disk, a new hard disk bracket matched with the solid state hard disk needs to be separately arranged, the cost is high, and the replacement mode is complex.
