Guys,Unless the fragmentation it is super extreme (I'm talking really bad, like 50% or something) and causing stuttering, fragmentation isn't going to affect your framerate. I think this whole idea that FS must be on a separate HD for best framerate is honestly another one of these long-standing myths in the sim community that isn't really true - especially if we're talking about SSDs. As long as you defragment semi-regularly it doesn't really matter with a mechanical HD either. A defragmented HD with both the OS and FSX on it is still defragmented... The only reason I put them on separate drives myself is that it makes defrag runs shorter because it doesn't have to go through all the OS and other stuff that would be there on a single drive too. There's going to be some very minor load time improvements from having it on the outer edge of the disk, but it's so slight that most people won't even notice it.Btw on that one comment about installing FSX to the root of a drive - I see no reason that wouldn't work - D: or whatever just becomes the FSX root folder. I'm not sure why you'd do this though, that doesn't make it "better" at all or anything like that.

Thanks for the post Ryan. I use the SSD ONLY for faster loading times. I saw 0 FPS increase...
