UDMA/33 vs. UDMA/6
I need a new HD. I can save about 30% if I buy an older model with UDMA 33. My Abit BP6 supports both. How significant is the performance difference between the two HD types?
I'd disagree with dbrunton. I have two almost identical systems. One has a UDMA 33 drive and the other has a UDMA 66 drive. The disk performance is noticeable faster the the WinBench DiskIO mark is almost 2X faster.
Go for the fast disk. There are more important things to do in life but sit around growing old waiting for a slow disk drive!!
I would agree with the SCSI assertion, however. If you've ever used a system with a 10000 rpm Ultra-Wide SCSI hard disk and an Adapter 2940-UW controller, you will know what speed is... If cost is no object, then this is the way to go.

Recommendation. Buy the UDMA 33 and save the money. I doubt if you would notice the difference. If you do need fast hard drive speed then you should be looking at SCSI.
