I have similar problems. I have a ASUS P8Z68-V PRO motherboard with OCZ Agility 3 AGT3 SSD.
dmesg shows: [ 2.152809] ata1: SATA link up 6.0 Gbps (SStatus 133 SControl 300) when connected to a 6.0Gb/s port. But hdparm -tT /dev/sda shows: Timing cached reads: 33220 MB in 2.00 seconds = 16629.95 MB/sec Timing buffered disk reads: 810 MB in 3.00 seconds = 269.77 MB/sec Whether I am connected to the 3Gb/s or the 6Gb/s port (with a 6Gb/s drive there should be SOME difference in speed between being on a 3 and a 6 Gb/s port) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/889071 Title: SATA III recognized as SATA II (ubuntu 11.10, chipset intel z68) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/889071/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
