JazZ, the issue you are reporting is an upstream one and it would be
nice if somebody having it could send the bug to the developers of the
software by following the instructions verbatim at
https://wiki.ubuntu.com/Bugs/Upstream/kernel . If you have done so,
please tell us the number of the upstream bug (or the link), so we can
add a bugwatch that will inform us about the status. Thanks in advance.
Marking Triaged Medium as this is a performance problem with a non-
essential hardware component (removable HDD).
** Description changed:
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.
+ My chipset is the intel Z68, and I have updated both the motherboard's
+ and SSD's BIOS. The AHCI mode is activated.
Since Ubuntu 12.04, the hdd speed go from 330Mo/s to 360Mo/so.
I have tested the kenerl 3.4 rc6 without any improvement.
