I have the GIGABYTE GA-Z87X-D3H INTEL Z87 CORSSFIREX MB as we speak and just got a new seagate 2TB SSHD. I was wondering which setting in the BIOS should I have the SATA controller at. Right now I have it on AHCI but I am not getting the starting speed at all. Didn't know if anyone knew if my settings where wrong somewhere. If someone could help me out with figuring out the BIOS setting that would mean a lot to me. Thanks.
