It does not matter much if the board is ATA 33 or 66. The main problem is
getting your disk to be read is UDMA rather than PIO
My original tests are below and I was at a loss to figure out why the P700
was so slow
I tested the following on a number of systems
Read & write mode mode: 65536 blocks - Test file size: 10Mb
CPU Op Sys ATA read write
P500 Win2000 66 19284 13281
P700 NTSP6 66 3385 2662
P400 Win98SE 33 5234 5389
P350 Win98SE Old 5130 4980
P333 NTSP6 33 3256 2228
Here are the new results on the P700 changing to UDMA
P700 NT SP6 66 10882 9650
This is greater than a 220% improvement
Thanks to Bob Perry
I found the following site that was useful

It is not just the improved I/O but the reduction on CPU utilization
Thanks to all that got me started on this track - it has made a big
improvemnt.
