When I use Dxtory to run a write speed benchmark on my hard drive it only get's around 47mb/s on average. But when I do the same benchmark again while Skyrim is open I get around 15mb/s on average. I know this would effect loading times for my games which I'm not too bothered about, I'm just curious if it actually effects the overall performance of my games. I've started playing Skyrim again and I seem to notice a great decrease in performance. When I used to play I'd have around 60FPS solid while playing on the full graphics settings but now I've started playing it seems to run worse then it previously did. So I'm wondering if my slow hard drive is the cause of the performance drop. All help is appreciated
