USB3 Speed test

I recently bought an external hard disk docking station (see attached picture) that has a new USB3 connection. I put a USB3 card in my PC and did some speed tests by comparing the speed when the docking station was plugged into the USB2 and the USB3 ports on my PC. Here are the results:

Test data: 40 x 20,925 KB .fit files (typical imaging session?). Total 817Mb

Copy from PC to Hard Disk:
USB2 = 41 sec
USB3 = 20 sec

Copy files from Hard Disk to PC
USB2 = 26 sec
USB3 = 14 sec

As an aside, it took 4:03 to copy the same files across my wireless network (from the observatory to the house) and 1:16 to copy them across my CAT5 network from PC to PC.
