    Mac Pro 3.1 Is it worth to buy a pcie usb 3.0 card and installed on PCIE 1.0?

    PCIE 2.0 is occupied by graphic cards and ssd.

    Thanks in advance.

    I sold an Inateck 4004 USB 3 card to a client who installed it in his 2008 3,1 Mac Pro and he said he is satisfied with the performance despite being installed in a PCIe 1.0 slot. He also installed a Newertech USB 3 card on his second 2008 Mac Pro and works fine. Here is a video of a guy installing USB 3.0 on his 2008 Mac Pro. I think it's still worth it.

    It should be worth it. A USB 3.0 rotational hard drive will get about 150-200MB/s. PCIe 1.0 is limited to 250MB/s, so the rotational hard drive itself is the limit, not the slot.

    In other words, my USB 3.0 drives should be just as fast on your computer with PCIe 1.0 as on mine with PCIe 2.0.

    A USB 3.0 SSD will be limited by the PCIe 1.0 slot, but it will still be faster than the rotational drive and much, much faster than USB 2.0.

    Even in the worst case it will be a lot faster than usb 2.0, so I would say it's worth it.

    One thing to have in mind is the possible bluetooth interference... some shielding may be needed.
