SATA question

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. =========================== ata3: SATA max UDMA/133 cmd 0x9E0 ctl 0xBE2 bmdma 0xC400 irq 225 ata4: SATA max UDMA/133 cmd 0x960 ctl 0xB62 bmdma 0xC408 irq 225 ata3: SATA link up 3.0 Gbps (SStatus 123) ata3: dev 0 cfg 49:2f00 82:746b 83:7f01 84:4023 85:7469 86:3e01 87:4023 88:407f ata3: dev 0 ATA-7, max UDMA/133, 390721968 sectors: LBA48 nv_sata: Primary device added nv_sata: Primary device removed nv_sata: Secondary device added nv_sata: Secondary device removed ata3: dev 0 configured for UDMA/133 scsi2 : sata_nv ata4: SATA link down (SStatus 0) scsi3 : sata_nv Vendor: ATA Model: WDC WD2000JS-55M Rev: 02.0 Type: Direct-Access ANSI SCSI revision: 05 SCSI device sda: 390721968 512-byte hdwr sectors (200050 MB) sda: Write Protect is off sda: Mode Sense: 00 3a 00 00 SCSI device sda: drive cache: write back SCSI device sda: 390721968 512-byte hdwr sectors (200050 MB) sda: Write Protect is off sda: Mode Sense: 00 3a 00 00 SCSI device sda: drive cache: write back sda: sda1 sda2 sda3 sd 2:0:0:0: Attached scsi disk sda
