    Can do.

    Kovan is correct. There are motherboards which support up to 8 IDE devices. I do not think there are Motherboards which support more. ASUS is the only one I know about, but perhaps there are others.

    I think most Network servers use SCSI (? spelling) drives which can be chained. SCSI controllers can support more than 8 drives (I think). These drives used to be a lot more expensive that IDE drives and the controller was an additional expense. Not sure what the current cost comparisons are. IDE drives used to be a lot slower than SCSI, but I am not sure that is true today.n

    I have an system with 3 hard drives, a CD, & a CD-WR. The Motherboard will support 3 more if need be.

    Indeed, a lot of modern motherboards will support 8 IDE drives. ABIT, is another one, and a great board for Athlon’s. This board can support RAID arrays as well without an extra controller, it’s a very nice board.

    The reason 8 devices are supported now days is because of the change in standards for the speed at which IDE works. The older IDE controllers supported UDMA 33 and 66, while we now have UDMA 100. So the extra two IDE controllers on modern motherboards are for UDMA 100 devices, though older legacy drives should work.

    SCSI is also another option, but a more expensive one. First you would need a SCSI controller card, if you want a decent one, it can cost a lot by itself. SCSI DVD and CD RW devices will cost a little more than their IDE equivalents, but will offer little performance gain. SCSI Hard drives on the other hand, are a lot more expensive, but they are also a lot faster as well.

    I believe that SCSI will support 15 devices that are daisy chained together on the one controller card.
    Iain, thats with an i by the way!
