If you connect UDMA100 HD to UDMA66 interface, the > performance of the drive decreases signifacantly and non-proportionally > (I'm not sure exactly why it is so now) Well the Seagate UDMA100 on a UDMA 66 BUS was much quicker as the UDMA 66 disk that came with the machine.... They both were primary ..... So I can't second that .... Maybe its even faster when using a real UDMA 100 controller, but I couldn't notice such a degradation as you mention.
