I have a dell Precision m6400 laptop.  I just bought a diablotek usb3.0 express card and i want to transfer 400gb from one external usb3.0 drive to another.  Im only getting around 47mbs through this card when doing the transfer.  I have an external power plugged into the express card as well to make sure I have enough power.  Any suggestions?

Is the transfer rate 47 Mbps (megabits/second) or MBps (megabytes/second)?

You've still only the one hub even though it's a faster USB 3.0 one. If you are using it for two separate devices you're having to divide up the bandwidth for each's I/O process plus the data has to go through the m6400's bus.

You may actually see a small improvement using the separate Express card's hub and the m6400's built-in USB 2.0 hub.  Connecting drives to copy in this way is always going to be much slower.

Thanks, I didnt think about that.  It was actually a little faster using the usb3 hub and the usb2 built in port. Thanks
