SATA question

[Ivan Gyurdiev]

I'm confused... is my sata drive (ata3 below) running at the proper speed?
This is a western digital SATA 2 drive. The messages below mention both  
3.0Gbps and UDMA/133, which I don't understand.

hdparm -I says udma6 is being used.
Testing my old drive, with this new SATA II one shows very similar 
performance,  near 60MB/s (via hdparm -Tt). Is this unusual? I would 
expect some kind of improvement...

This is an nforce4 chipset, A8N-SLI motherboard.
