Progress sucks
My dually system runs 2 IBM Ultrastar 10,000RPM SCSI drives... they benchmark ~20000kbps in sisoft. My new 80gb 7200rpm Maxtor IDEs on my KX7 do

,000kbps off the reference 15k rpm scsi drive, and they AREN'T raided... they do 40,000kbs+ each
I paid $500 and $300 for the IBM 36.7GB and 18.2GB SCSIs respectively something like 2 or 3 years ago. I paid <$200 for the Maxtors, and if I could find my recipts I could have gotten them for $60 each...
Progress sucks.
(of course now I have a reason to buy some WD Raptors or something...

)
