I use Bandicam to record, if does not decrease the frames by that much compared to other recording software so that's a pro.
That's the reason why I stopped using FRAPS. I would suck my FPS from 60 down to 45. It apparently uses alot of resources. I liked dxtory because I could play in 1080p and it would auto scale it down to 720p to save disk space. As for the hard drive I just record it to my ssd and then move the files to a wd black drive when it gets full. to process the videos for my youtube channel.
