Solid state drive since the advent of the heart of the game players, super read and write performance let the computer get rid of the bondage of mechanical hard disk, so that the whole machine performance can be greatly improved, with faster speed, SSD even let many old computers revitalized, but the popularity of solid state drive or experienced difficulties.
