It's actually a bit of a shame to have that fast 1TB as your system drive, as the ideal is keep the system drive clean, except for OS and programs. Still, it's fast, and that counts.
My workstation is set up this way:
C:\ OS and programs with part of Page File
D:\ Media and other part of Page File
E:\ Projects and Scratch Disks in Project folder structure
F:\ Exports Video
G:\ Audio files
H:\ Media storage
Gigabit NAS media archival storage. I bring these Assets onto D:\ as copies, so I am never working with originals - other than Capture files from tape, but I archive my tapes, in case I have to recapture
I also have 2 multi-drives of different brands and a couple dozen 2TB FW-800 externals for archiving Projects, or for transporting Project between the workstation and my laptop.
I tested my Page File and found the best results on the workstation with it fixed and split. The next best was fixed and on D:\. It differs machine to machine, as it's better fixed and on D:\ on my laptop with 3 identical 200GB SATA II's. Given your C:\'s speed and size, I'd experiment with it fixed and on C:\ to see what performance increase, or hit, you take.
Thanks for the reply! It is a shame that the 1TB was chosen as the primary drive but it was done intentionally! One reason being I was able to purchase the drive for $89.00 the other reason is because of the speed of the drive! I specifically chose the Black edition for speed! I would have purchased a WD Velociraptor if I could have afforded it!
