For optimal performance in Adobe Camera Raw and Photoshop CS5 (I will soon upgrade to CS6 or CC), how should I distribute my OS, apps, Scratch, Caches, DNGs, and working TIFFs among these drives?:
120 GB OWC Mercury Extreme Pro 6G SSD
(connected via internal 6G SATA)
240 GB OWC Mercury Extreme Pro 6G SSD
(connected via internal 6G SATA)
960 GB OWC Mercury Accelsior SSD
(connected via Thunderbolt TB1 external OWC Helios unit)
(Also, irrelevant to performance: multiple individual hard drives connected via eSATA and USB3, not RAIDed together [these are for bootable backup of the OS; for backup of all of the above; for archives of past work; for backup of archives of past work, etc.; on site and off site.)
The Accelsior SSD, connected by TB1, is by far the fastest drive. Would partitioning and devoting different parts of it to different functions help?
I'm able to fit the OS, apps, email, etc. on the 120 GB SSD. But I don't assume that I should.
Here's the most relevent info about the rest of my hardware:
