I recently upgraded to an ASUS P4P800 motherboard with 512M
DDR3200Operating system is XP with SP1. I added a Seagate 120m SATA-IDE
drive. Running Sandra benchmark it shows I am only getting about
39mb/sec
transfer rate. I believe it should be more like 150mb/s.

Additional config info:

IDE-0 master is a maxtor 80gb ide.
slave is sony CD
IDE-1 master Sony CDRW
slave unused for now

SATA 0 - the segate 120gb

also have an Adaptec-2940UW in a pci slot controlling 2-18gb scsi
drives.

Any ideas why teh SAT drive would show such poor performance?

TIA, Brian

Nope, 150MB/s is the theoretical bus rate, not the actual possible
rate, and certainly not the max the HDD can deliver. Still the 39MB/s
sounds a bit low, but not much, considering Sandra, and that you
probably formatted it as NTFS, which is slower than FAT32.

You could also try the DVStorm benchmark.
As fragmentation affects benchmarking, defragment your drive(s) before.
With my Maxtor 120 GB (8 MB cache, 7200 rpm), results vary between 51 and 55
MB / sec.

You should have gotten the Raptor.

Speed kills...and sometimes that's good! lol
