Because physical memory performs operations much, much faster than hard disk, RAM disk can greatly improve application performance. Given that large capacity memory is now widely available and mostly idle, so we can use software like GiliSoft RAMDisk to create free memory as virtual hard drives for use, thus increasing the running speed of software or system many times.

By modifying the environment variables of system or software to save a variety of commonly used temporary folders (Temp, IE Cache, Download folder, for example) to the virtual hard disk (RAM drive), we can effectively improve the file reading/writing speed and software running speed. And in fact, it can also reduce the reading/writing times of physical disk so as to prolong its service life to some extent.
