very nice datapoint. care to elaborate on HD setup? i guess this is
using PV drivers, but the hardware side is also very significant.

We have 8 250gig Seagate SATA drives (ST3250410AS) in RAID 10 on a 3ware 9650SE-8LPML raid controller. We are NOT using PV drivers yet. Performance is pretty good. I'm sure it will be better once the PV drivers mature. Could get some benchmarks if you are interested.
