HDDTurbo is a great tool that allows turn a piece of our RAM disk caching for performance increase system. Not much to explain, but for those who do not know, RAM is much faster than a hard drive, therefore, if we have the cache stored in RAM will be greatly increasing computer performance.
What I liked is that the little program is very simple to use as it has a minimalist interface. The requirement to do this is to have at least 4GB of RAM and running 64-bit versions of Windows 7 and 8.
