    Hi, dear all who can help :

    I built RAID1 via Marvell GSATA controller, but something strange.
    MB = GA-P55A-UD4(v.1) BIOS = F12
    HDD attached to Gsata = Seagate 3 TB ST3000DM001 and ST3000vx001, all SATA3
    Virtual disk as RAID1, seems to be ok

    But after boot to OSX, I see SATA/SATA Express under "About My Mac", it shows negotiated link speed = 1.5gb(that is sata1 speed?)
    Then I further examine my BIOS settings to see what might cause it, but it seems to be okay.
    Then all in a glimpse when reboot from BIOS, I see a quick screen popup "PCI Express SATA II.....", it is too fast that I can't get a picture of it. Besides, it is not any sort of error that will cause boot-up to be stopped.

    Attached please find some clue pngs, that I think you might help to explain why and teach me how to resolve this issue.

    Thanks a lot.
