Guys I would either try a very fast modern flash drive like a Sandisk Ultra or something with a very fast read/write (esp read) rate.
Makes a noticable difference. If not a USB stick then a really fast MicroSD UHS-I U1 or U3 card, in a microSD to USB adapter (costs like a buck on Ebay).
I was using some throwaway flash drives from tradeshows and those are incredibly slow.
