ATA Controller Cards?

  1. I currently have both ATA channels full on my motherboard (DVD and a CD writer on one, plus my 40/80 gig HDs on another). If I buy a PCI controller card, will I still get ATA 100 transfer speeds, or are the transfer speeds limited to the speed of the PCI bus?

    The speed of the PCI IDE-controller decides how fast your HD's can run. With a 133-card you can run ATA-133/100/66/33 HD's.
    Note that the lowest speed of a pair of HD's (say 133 and 100) is the one that will be maintained (in my example both HDs will run at 100).

    Something to seriously consider is a more powerful Powersupply. Go for 430 or higher wattage and buy a brand-name like Enermax or Antec etc.

    He meant, will the speed of his PCI bus limit the max data transfer rate his PCI card will do..

    No, the extra card will let the HDs on it run at their own speed, independent of the mobo's PCI-bus speed.
