OK I just got a new Nehalem quad core Mac Pro. I am new to Mac and I bought it because I will be doing some heavy video editing. I have 4 harddrives for it, a 640gb that came with it, and 3 1TB seagates barracuda's. My question is exactly how I should set up my RAID config to be as fast as possible? I have read some articles about RAID 0 on Mac Pro's but am a little confused. Setups that any of you use would be much appreciated.
