I have an early 2008 Mac Pro quad core 2.8. It currently has 10 gb of ram and the original 320 gb HDD. I'm interested in running OS X and all my applications off a medium sized SSD (120 gb enough?) and keeping everything else on the original hdd and a new added drive (like a 1 TB WD or something). I guess my question would be if there is anything about that setup that wouldn't be optimal, and how would I get OS X and my applications to the new SSD? Thanks!
