best folder settings onto which drives

Hi

Its mentioned here before but not exactly clear. For Vegas 11 pro what is the best way to set up a project on which drives if this was the disks available

I have

C drive - SSD sata 3
D drive - 2Tb 7200rpm sata 3
G Drive - 2Tb 7200rpm sata 2
H drive - 1 tb 7200rpm sata 2

obviously the program goes on the C drive, but does anything else?

in which drive would I name and save the project?
which drive would be best for the video files?
which drive best for the scratch folders?
which drive best to save the final render to?

I'm wondering if the sata 3 conection is better used on a particular function that might not seem obvious. for example would having the original video files on the sata 3 connection make editing smoother as it can read faster or would it not matter so much as using that faster sata 3 or faster drive in general for the final render be more useful say?

any help clearing this up would be much appreciated

Thanks John!

Sorry for the late thank you, but big kudos to you. That explains it exactly as I wanted to know! Since using the sata2 and sata3 drives in this way, I have noticed playback in general has been smoother as well
