At the moment ive got 5 drives with a total of 18tb, i can fit another drive in but if i went for 6 2tb ssds, that still only gives me 12tb... its bad when you've got so much 'STUFF' (cough cough) on your computer hehe, i suppose the easiest for now would be a few 8tb hdds and see what the prices look like in a year or three...
