Hi, my mac pro should be arriving in the next few weeks. just wondering if a 10,000 rpm drive matters that much and if raid matters that much. I have a pc right now and the main drive is 10,000 rpm. I've never had a drive less then that so I dont know if its really that much faster. also the mac does raid I think. so should I set 2 drives up in raid? will it be that much faster? I was going to stick with the 320 standard one as my main drive and buy a 1TB as my time machine drive. Then I have a few 500 gig drives I was going to put in for other things. no raid though. I had raid on my PC for a while and it kept screwing up and ruining my life so I gave up on it. but maybe it will be more stable with the mac. anyways let me know if it is really worth it to use the full potential of the computer. I basically am using this for everything in the adobe creative suite and Protools. so really everything media intensive my config that I am receiving is: 2.8 (2 quads) 6 gigs ram ( 4 gigs bought online ) 320 gig hard drive. Oh and one ram question. should I have all 4 sticks on one of the two ram "cards" or should I have 2 on each.
