Hi, I have currently a MacPro 2011, 12 core with 24GB RAM and a OWC 60gb SSD for my apps and the same drive for Photoshop working files. I need to improve my performance with Photoshop. I mostly work on huge (1GB up) files with tons of layers. I am planning to get more RAM, to total 48GB for the machine. I want also to get another SSD just to run my Photoshop files on it. I was looking into the Accelsior from OWC or any other options that is more $$ reasonable. Any suggestions? My question is if I am going in the right direction and if I should do a RAID on my new SSD or buy two SSDs with one for scratch disk and another to place the files. I appreciate any tips and advice.
