Comment 0 for bug 889071

Hello,

My SSD OCZ vertex 3 60Go SATAIII and my WesternDigital 500Go/s SATAIII are recognized as SATA II discs, according to palimpsest. When I run hdparm -tT /dev/sd?, it returns me that my SSD works à 300Mo/s which means that the disc is effectively limited by the SATA II norm. I have tested the same configuration under windows, and the SSD runs at 480Mo/s in average.

My chipset is the intel Z68, and I have updated both BIOS's motherboard and BIOS's SSD. The AHCI mode is activated.

I have made lot of researches on the web, and the only subjects which talk about the SATA III refers to problems of HDD detection on linux distributions relatively old. No web site talks about my problem.

Is there a solution to activate the SATA III, or should I wait for the next kernel ?

Thanks.
