Is there a faster way to transfer files to PC?

Since I've started recording in 4K, my videos are getting pretty big.

I just use an SD card reader plugged into a USB hub, plugged into my computer. It can take a pretty long time to copy the files over.

Is there a faster way? My PC does have "SS" USB 3.0 ports, but I get the impression that either the hub or the SD card reader isn't actually taking advantage of them.
