Q: my left side USB port is slow on macbook pro retina (2013)

Tried backing up data to WD passport drive (USB3 type) on left side and it was taking too long.  Swapped to right side and it was a lot faster (x5).  Any ideas?  Seems left side is way slower than right hand side...

MacBook Pro with Retina display, OS X Mavericks (10.9.5), 15" 2013 model
