I just got the asus p4b533 with the built-in promise raid 133. I am going to run two hard drives for audio on the raid. should i go for the maxtor 80 gigs which run at ata133, or the western digital 80 gig which only runs at ata100, but has the 8mb buffer? Would the bigger buffer give me more performance? or the true ata133 speed of the maxtor?
