    If I install WinXP x64 and the latest promise 64bit drivers onto my A8V
    Deluxe, will I be able to use any of the newer, and much larger, 2nd
    generation SATA hard drives with my system?

    Thanks in advance,

    If you are talking about SATAII, then no. Your motherboard SATA controller
    must support SATA II. You can buy a PCI card that will add SATAII to your
    existing motherboard, although I can think of very little reason for the
    average user to do so. Games are designed with the original SATA specs, so
    SATAII will not improve gaming performance, and as a casual user I cannot
    see anyone having databases or other files large enough that are accessed
    frequently enough to justify SATAII. In short, SATA is more than sufficient
    for 99% of the casual users needs, and will be for a long time.

    You can buy and install the SATAII drives, and your system will see the full
    capacity, but will only operate at SATA (150Gbs/burst) speeds.

    You might consider looking at NCQ technology, as it delivers consistently
    faster performance (SATA will still beat it in "burst" mode). NCQ allows
    data to be read out of sequence from the drive and then delivered to the
    buffer is the proper sequence; result is less thrashing and greater
    sustained throughput.

    Again, your chipset must support NCQ, and as your motherboard currently does
    not, you'll have to add a PCI card to support it.

    No. You would need to download a motherboard BIOS update, IF there is such
    a one, that converts your SATA controller on the motherboard to SATA II.
    Then you would need to download and install the necessary SATA II drivers.

    I have is a pair of 300GB Maxtor DiamondMax 10 SATA-150 hard drives.
    These drives do support NCQ.


    I bought them for use with a different system (an A8N-SLI) but never could
    get them to work properly.

    I was hoping they might work with this A8V Deluxe system I'm building.

    I don't see why the manufacturers wouldn't make these darn things
    backwardly compatible!!!

    If these hard drives won't work with the onboard controllers, can you
    recommend a RAID capable PCI card?

    Thanks Again,

    Your drives are first Gen SATA 150 drives; SATA II is 300Mbps and NCQ
    depends on what kind of motherboard you have (NCQ will be faster on an AMD
    system with Hypertransport than on an Intel system that still uses a
    northbridge). As stated, if your motherboard does not have an onboard NCQ
    controller, you will need to buy a PCI card to get the advantage of NCQ. I
    would first check and see if Maxtor offers one, but otherwise I would just
    visit my local CompUSA or other computer store and see what NCQ PCI cards
    they have in stock. One last thing, a minor consideration that may or may
    not apply in your case...If you go with a PCI card, make sure you put it in
    a bus master capable PCI slot, as you must be able to boot from it. With
    you mobo, I think all the PCI slots are Bus master slots, so it should be no
    problem; I would check the manual just to be sure.

    Good luck and post back with your progress...

    One closing thought...when I build a system for either myself or a client, I
    always use Seagate hard drives. They are by far the quietest, coolest and
    most reliable drives I have ever used. All of their internal drives come
    with a 5 year warranty, and they will be first to market with a new
    perpendicular recording drive. I have a little cash put aside to try one of
    those when I can get one....

    Notice the approach that Hitachi/IBM is taking with their drives
    in the following document. The drives ship operating at 1.5Gbits/sec
    on the link, requiring the user to manually set the drive to
    3.0Gbits/sec. This is to prevent situations where you cannot
    communicate from a 1.5Gbit/sec motherboard to a 3.0Gbit/sec
    drive. If you flip this control to the 3Gbit/sec setting while
    the drive is connected to a 1.5Gbit/sec motherboard, then you
    must find a 3.0Gbit/sec motherboard in order to reestablish
    communication with it, and use the Feature Tool to flip it back.

    See PDF page 22:

    That covers the disk end - I don't know what controls the
    motherboard end of things has, and whether discovery is totally
    automatic. You would hope a 3.0Gbit/sec motherboard, would try
    both 3.0Gbit/sec and then fall back to 1.5Gbit/sec, until it
    gets good CRC on the link.
