I have an Intel SSD that I put my games on. it's incredibly fast but you really don't want to use it for your main drive or any drive that your page file might be one. I found that with my motherboard and setup that if I used it for the O/S that once in a while it would lock up for several seconds ( pagefile on it). As a secondary drive that I install all of my games to it never locks up and runs great.

I tried all combinations of it, as an O/S drive, as just a pagefile + games drive, just a games drive. I know my games load faster but I couldn't really tell you how much faster... I 5x box and all of the games start with roughly the keyclone delay.
