    Hi, i recently had to copy a lot of files from some USB drives (with USB 3.0 connectors) and I noticed that all of a sudden none of my ports on the Inateck PCIe USB 3 card were working anymore.

    They are showing up in system profiler as connected to the "USB 3.0 Superspeed Bus" 5Gbs/s. However I am copying at 20MB/s....

    Any thoughts on what the issue could be?

    I tested this with some 90MB/s capable SD cards on my high speed card reader and I have similar results.

    Both drives work at high speeds on my macbook pro using the USB3 port...

    Any thoughts?

    Cheers!

    I had an Inatek card that just died one day... Replacing it fixed all problems.

    Hi, It's an Inateck KT4004. Do you need to know more?

    No, that's fine. I just wanted to know.

    It's a bit weird that it's working, but slow. This indicates the card isn't dead. If possible I'd try a different cable, a different drive, or a different slot.

    You can also eliminate software/OS issues if you have boot camp partition to try it there, or a clean install of OS X on another boot drive.

    Were you using the same cable that was hooked up to the Inateck card when you tested speed on your Macbook Pro? If not, maybe the cable you used to connect to the Inateck card isn't rated for USB3 speeds.
