Comment 12 for bug 889071

Hi Christopher, the problems occurs since ubuntu 11.10. I can't tell if the problem was the same before this release, because I have not got already my SSD before. So I have not observed a regression. Just a little progression : 330Mo/s instead of 300Mo/s since ubuntu 12.04.

dmesg screen me this :
[ 0.640125] ahci 0000:00:1f.2: >AHCI 0001.0300 32 slots 6 ports 6 Gbps 0x7 impl SATA mode

I can see that SATA III is recognized for two of my drivers (one SSD and one standard disk). The other drive is an optical disk. But I am not really sure about the signification of UDMA/133. This protocol is old.
