Is my computer copying files slowly because of my USB drive?

I have a Lenovo W530 with a SSD Samsung drive, 16GB of RAM, and am running Win8 Pro x64on an I7 processor. My flashdrive is a 32GB Sandisk.

Every time I copy a file to it it is really slow. (Currently I have speeds between 2 and 4 mbps). Is It copying so slowly because of the USB limitations?

That's slower than USB 1.0 check which slot is USB 2 or 3
