I found I was getting timeouts with this controller and exactly those 
drives even with the SATA150 jumper connected.

In the end I got a PCI Silicon Image 3114 based controller and it worked 

That said I gave up on the hardware as I couldn't get the motherboard to 
boot off the CF/IDE adapter so I got an AMD SB700 based board which 
works well (fingers crossed :)

I didn't do any stand alone drive performance tests though.
