    I've read that you cannot daisy chain FW400 and 800 together without the everything in the chain going down to FW400 speeds.
    If I get an express card for FW400, will it also share the bus of the dedicated port and reduce all speeds to FW400 or will I be able to get both FW400 and FW800 speeds on the same machine?

    You're going to be connecting over a PCI-Express x1 lane independent of the FireWire controller.

    So that means that I will be able run devices with both FW800 and FW400 speeds and not be slowed down by the 400?

    Forgive me, I am new to this port/bus stuff.

    That is correct. The FireWire controller and the ExpressCard slot operate over different connections.

    I have a semi related question... I have a quad interface HDD and I could connect it to my iMac via FW800 or I can connect it to my AEBS.

    I'm looking for the fastest way I can share it over my network = which would be best or will it not matter except to the iMac that its connected directly to with the FW?
