    Default Gigabit and PCI

    Would there be any advantage in upgrading my home server from fast ethernet (integrated in the motherboard) to gigabit via a pci card or would the pci slot make it slower?

    Unless everything else is gigabit, it wont make a diff.

    All other computers are gigabit capable, so if there would be an advantage I'd go and buy a gigabit card and switch.

    Oh well, in that case, it should be at gigabit speed. If all and the switch are gigabit. So, should be faster, for transferring files

    So you're saying that the pci bus wouldn't make to much of a difference?

    Well it'll make a diff in speed. Since the onboard NIC isnt GB is it.

    The card is. It shouldnt be slower. If it says its a GB card, it should give you GB speeds

    The pci bus is indeed slower, try pci-e...x1 or x4

    Maximum speed is 1000Mbit, converted equals a maximum theoretical throughput of 125MB per second. the PCI Bus can transfer 133MB/s so this is within the limits. Of course, other factors will probably take your networks maximum speed lower than this, to about 80% of maximum or less

    You can put a slower speed card (PCI-E 1x) into a PCI-E 16x slot
    Non-system disk or disk error. Replace and strike any key when ready.

    How are you calculating 1/4 speed?, you are correct in that hard` disc will also use the pci bus bandwidth but i dont follow your 25% step down??
