I will be purchasing the 27 inch iMac when it becomes available to use with Avid. I am tossing around between which hard drive I should be getting. I have a g-raid external for all my video so I don't feel I need more then 1tb of internal storage. Which route would you guys reccomend me to go? I feel fusion might be to gimmicky for professional use? Or am I wrong. I'm leaning towards 1tb 7200 rpm hard drive unless someone feels I should go another route?
