    On a motherboard supplied with two IDE connectors you can install up to four
    hard drives (two per connector).

    Of course, this will prohibit the connection of any other IDE device to
    either of those connectors.

    On boards with PCI slots you can install at least one card that will allow
    the connection of up to four more hard drives.
    Some motherboards and operating systems may allow the use of up to two or
    three of those cards, thus permitting up to sixteen hard drives.

    In my opinion, if you need to exceed eight ATA/IDE devices, you should
    either add or switch to SCSI devices.

    The drives do not have to be the same size.

    Just be certain that your power supply is of high quality and is capable of
    handling all the devices plus the motherboard components.

    The estimate of power consumption that I use when building is 20 Watts,
    for a standard hard drive, either IDE or SCSI, unless something higher
    is posted on the drive label or the website. There is a difference in
    power useage, for a drive upon startup (surge), vs. one running (or,
    idle). Some Operating Systems have options to delay the start-up of
    hard drives...

    Much good info in the book "Building and Repairing Your PC"

    Also, you may want to consider external / removable hard drives. They
    often connect through a usb port. Computers made within the last four
    years or so often come with around four to eight usb ports, allowing
    for four to eight extra hard drives. For older computers without usb
    ports (or just another option), there are external hard dives that
    connect through serial ports. Though external hard drives are usually
    more expensive than traditional IDE or PCI hard drives, they offer

    It depends on the design of the motherboard you're using. A 'typical'
    motherboard can use up to four harddrives, if you don't use any CD_ROMs or

    You can have up to 128 USB devices. In theory, 128 Hard Drives. You'd have
    to crazy to try, but it's supposed to be possible.
    IDE - 2 devices per channel: Ron's right, in his post.
    SCSI - 14 devices per channel. Some variations of SCSI are said to be
    I haven't messed with SATA enough to know. Anyone out there know?
    Could also consider other forms of connections to the PC like Ethernet.(SAN,

    Power, Space and Money are the only real limits.
