Hey, quick question here for those more knowledgeable than me... I just received my mac pro (Yay!) and I'm trying to figure out whether to use the one 250 gig drive that came in it with OS X installed as my boot drive, or install OS X on my Seagate Barracuda 320 gig drive and use that as the main drive. I'm just wondering if there's going to be much of a difference in terms of speed, or if there's any other differences I should be aware of. Thanks for your help!
