I know there will be plenty to say, and this is only my second post on the forum, but trust that I understand what I am asking.
I know that the real world difference between SATA generations for HDDs is miniscule. I also know how to implement, and check the storage controllers.
I have the correct drivers, and REGARDLESS OF MY REASONS, I would like to know why my Seagate 5400.6 is running at SATA 1.5 and not SATA 3.0.
I checked it over and over after installing the Chipset, the AHCI, and the RST driver. I even tried countless versions of both, so I am fairly sure that its not a driver or software issue. That leaves: The chipset, The "UEFI/BIOS", or the HDD firmware. I should also mention that my last, and only other experience with Lenovo was with the T61 series that had the SATA II governer placed on it. I don't know how you would feel about that, but I simply did not like it.
There is one other promising post that is hasnt been updated for a while, but on it there is information about seagate Firmware. That being said, I have seen the same issue, without resolution, tucked in the far reaches of the forums of cyberspace....Its a Mystery.
I should mention that the machine is question is a:
Lenovo V570 with the 2nd Gen i5 2450, Sandy Bridge Architecture (so not the 2 port intel problem) and HM65 Chipset(so perfectly capable of SATA II).
Windows 7 64bit

I'm also wondering this about my V570.
I went to install an SSD into the optical drive bay, and even though system states everything should be Sata 3 Capable (6gbits/sec) it was capping at sata II speeds (3gbits/sec).
Can others chime in on what the heck is going on here?
