I dont know exactly how much, but I have only seen noticable improvements with ATA-100 over ATA-66 in RAID configurations. A Fasttrak 100 with 3 IBM 7200 ATA-100 30gig's is faster than a Fasttrak 66 with 3 Western Digital 7200 ATA-66 30gig's. Thats the only pertinent experience I have with 66vs100 right now.
