    If your computer is 5 years old, you do not have USB 2.0, since it was not available 5 years ago.

    In terms of speed, firewire (IEEE 1394) is faster than USB 1.x, and USB 2.0 is faster than firewire. USB2.0 is backwards compatible with USB 1.x, but firewire is not compatible with either. Firewire was originally all the rage for connecting things like cameras to PCs because of its higher speed, but USB seems to have overtaken it now. If you have a particular product you want to connect check what sort of connection it has, they are not interchangeable.

    For USB 2.0 to operate at high speed you need WinXP SP1 or Win2K SP4 as a minimum, otherwise it only runs at USB 1.1 speed.

    Here's some lists of available cards:
    USB only
    Firewire only
    USB and Firewire
    .

    might i add that there is also firewire 800, which is twice as fast as the original firewire, and nearly twice as fast as USB 2.0

    check out http://www.tomshardware.com/storage/20040402/ for some more info on firewire advantages........

    Yes, because PCI is standard.

    The very first line of the first reply.

    You aren't going to get far if you don't even read that much.

    There's not much point in even considering Firewire 800 if the devices that you intend to connect don't support it. There are cards which will support Firewire 800 on a 32 bit bus, but since the 32-bit pci bus can only support 1066Mb/s maximum there won't be much time left for the system to do anything else. I doubt whether a 5 yr old pc would cope. And in any case they are expensive.
