    Default meaning of SATA3 Header labels

    My situation;

    About one year ago, in order to learn more about computers in general and linux in particular, I assembled the following system:
    Mother board is ASRock Z77 PRO4
    Processor is Intel I5-3570K
    Operating system is Linux Ubuntu
    HDD is Western digital 1 TB Blue SATA6.0
    Optical drive is Lite-on 12X Blue Ray Burner
    Power supply is 600w OCZ ModXstream-pro with Cooler Master cooler
    Case is MSI S-8810 AT

    just recently I have decided to move from my aging windows computer to the system described above. I did this by adding a second hard drive (Toshiba 500 MB) and installing Windows 7. This seemed like a less complicated and more secure approach then attempting to partition the original hard drive.

    My question:

    What is the significance of the header labels SATA3_0, SATA3_1, SATA3-A1 and SATA3-A2? Right now I have the hard drives in A1 (Linux/Western Digital) and A2 (Windows/Toshiba) and the optical drive is in SATA3_0. So far everything seems to work okay as it did with several other combinations I tried. Is there any preferred order for these items to be connected? I'm not really sure whether the optical drive even needs SATA3.

    Thanks, John

    Welcome to the forum.

    From page 38 in your motherboard user manual:

    2.13 Serial ATA3 (SATA3) Hard Disks Installation

    This motherboard adopts Intel® Z77 chipset that supports Serial ATA3 (SATA3) hard
    disks and RAID (RAID 0, RAID 1, RAID 5, RAID 10, Intel Rapid Storage and Intel
    Smart Response Technology) functions for SATA3_0 and SATA3_1 connectors.

    It also adopts ASMedia ASM1061 chipsets that supports Serial ATA3 (SATA3) hard
    disks for SATA3_A1 and SATA3_A2 connectors. You may install SATA3 hard disks
    on this motherboard for internal storage devices. This section will guide you to install
    the SATA3 hard disks.

    The Intel Sata3_x ports provide the best performance and your boot drive and one additional data drive should always use these ports. Third party sata3 solutions such as ASMedia have fewer features and provide somewhat lower performance. Sata2 ports have 50% of the maximum bandwidth, but they are fine for optical disks and hard drives, even if you have sata3 hard drives.

    Some motherboard brands or models have "issues" when your boot drive is not connected to the Intel sata3_0 port.
