Looking to put a 120 SSD in my Mac pro as a boot drive but not sure how best to set up along side my HDDs. This was my planned config, but open to advice: SSD - system + apps 2x 1tb set up as 2tb RAID 0 - work files + home folder 1tb - Time Machine This leaves one bay spare, but where would be the best place for my scratch disc, on the SSD? If so would a partition be the best option? Working in graphic design, mainly in Photoshop so performance is my main priority. Another thing to throw in the mix is what performance increase could I expect by replacing the HDD RAID with an SSD for my files, would this speed up open and save times?
