I would add more drives. a 3rd drive for your cache files and pagefile, and 4th drive for exporting files so premiere is not always reading and writing to the same drive.
I unfortunately i dont think you can turn off your pagefile with master collection, 6 cores, and only 12GB of ram, my machines all have 8 cores and 20GB ram and i think that is the bare minimum to turn it off, (all of my machines have pagefile disabled)
If you try to run photoshop, premiere, and after effects with multiframe rendering you will likely run out of ram.
honestly if i had your system and was upgrading it i would buy the new ocz vertex 3 ssd drive for my windows system drive and use that 600GB sata3 drive for pagefile, media cache, and afx cache.
Thank you both for advice
In my case I'm afraid for a while I can not add even a screw to my system
Should I split my disks to partitions Or this meant nothing?
(Although the partitions are on the same disk but still there is little difference in access to, is not it?)
maby i Should:
160 c: system
160 d: chach + pagefile
320 e: capture
1tb f: proview
1tb g: export
Also where I define the drives permanently??
