A seperate drive for FS? Please answer me!

If I chopped up my drive into a seperate area for my Flight SImulator would that benefit me? Currently it is swamped in C drive. Or would it not make any difference?
As you can see there is plenty of room for me to seperate 15 or 20Gigs or so just for FS, (My FS folder is currently just 6GB) but would it help?
This is C drive after defragging.

Thanks
Ben
