I have an early ’11 17″MBP with an OWC Data Doubler and 960GB Mercury Electra SSD in my optical bay, as well as a 1TB Samsung 850 Pro in my main bay. This has been very reliable, but I’m wondering if my setup optimizes performance, or not. I use Lightroom and Photoshop on a daily basis, and, due to the 3G/6G speed difference of the two drives, have put my OSX system (and applications) folder on a 100GB partition on the 6G Samsung, with a 2nd partition of that drive dedicated to my Lightroom catalogs and files. The other 3G drive in my optibay has my ‘home’ folder on it – about 700gb worth. I wondered if this is the smartest setup? I am keen to keep my work on a separate partition (this makes backing up via Superduper easiest) and I like having my home folder on a dedicated partition too, as I have found this the easiest way to switch between my life on the road, and, my desktop mac at home; when I get home, I Superduper my home folder to the home partition on my Mac Pro, and I can take up where I left on my laptop. I’m wondering whether I might be better having system and home partition on the optibay, despite this being 3G and the main 6G drive dedicated to work/scratch space; would this improve performance (Not that it’s sluggish right now, but still..)?
