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. ===========================
