Drives setup for Adobe Premiere and Photoshop

[dram9564]

Hello all
I'd be grateful for comments/suggestions on my proposed assignments of 4 drives for Premiere/PS CS5:
(1) ssd 250 - OS, win page file, programs
(2) ssd 250 - scratch (media cache, render preview etc)
(3) sata3 2tb - media / project files
(4) sata3 2tb - export / render outputs
No raid
Each of the 4 internal drives individually backed up to 4 external usb3 drives.

Many thanks!

I do a lot of Lightroom and similar work, and that's pretty much how I have this PC set up. Works quite well.
