reading and writing are frequent, and the head arm moves frequently under the drive of the track-seeking servo motor. However, for machinery, there is not much wear loss. Unless your hard disk itself has mechanical faults, such as force arm deformation (the most common faults of water products ). The real wear loss lies in the head. The changing current will lead to its aging, but compared with its lifetim
independent power to protect data security. Because of the use of flash storage media, it has no mechanical structure inside, so there is no data lookup time, delay time and seek time. As we all know, the mechanical characteristics of the general hard disk seriously limits the speed of data read and write, and SSD solid-state drives in the operating system is a common letter, users can completely use it as a storage medium.
