Put simply, it creates RAM disks. What's that, you say? It looks to your system like another hard drive, but with a BIG advantage: it's about 1000 times faster than your hard drive. It simply keeps all the data always in RAM, so it's lightning fast. Images, movies, programs, anything can go in it.
This app makes making RAM disks extremely easy. Set a size and name, and click create! Then you just need to copy whatever you want into it (happens very quickly). Because your HDD doesn't have to spin, you can even save battery life while watching movies.
