As Windows and third-party applications often create a large number of temporary files for a short time only, using a RAM disk will extend your hard disk's life by sparing it from excessive reading and writing. Furthermore, Windows can be configured to use the disk for temporary files, so the system and most applications will use the fast in-memory disk for temporary data. The program creates a virtual disk residing in the computer RAM accessible in Windows Explorer and other applications, allowing you to store any temporary information on this disk. As the memory is much faster than physical hard disks, it makes sense to store temporary data on a fast in-memory disk to achieve a higher performance and a longer life of your HDD or SSD.
Moreover, when using a RAM drive, the operating system can not reclaim the RAM for anything else.SoftPerfect RAM Disk is a high-performance RAM disk application that lets you have a disk on your computer entirely stored in the memory. If the operating system needs that RAM for another function, then it discards the cached data.
Modern operating systems store cache data in RAM automatically so that it can be retrieved quickly. This is not to say that using a RAM drive for caches is a good thing. This can be a significant negative when the shutdown is unexpected, but if you choose to save your app caches (such as a browser cache) or other sensitive data to a RAM drive, you can easily set the software to ensure it will be wiped when you power down your PC. There are also potential security advantages because RAM is erased when a computer's power supply is cut off. RAM also generates less heat, and it isn't susceptible to wear over time, nor does it have the finite limit on read/write cycles that physical drives have.
These can all be slow and unwieldy to work with, especially on a hard drive, so the added speed of a RAM drive will be noticeable instantly.
