so what i use is my lap top has 2 SSDs in it one is for cashing for my hard drive and the other is a boot drive and then i also have a WD m,y book live so i can transfer files between my devices easier. i find that the 2 ssd and 1 hdd in my lap top is giving me more speed on the mission critical stuff like 3ds max and all of that stuff but i put all of my games on the hdd so the speed on that is nice with the cashing ssd
