Speaking of the Quest Link, could some knowledgeable person answer a confusing question for me? 

My motherboard has two standard USB 3.1 sockets and two USB 3.0 Type-C sockets. 
Which would be better to use with the link? The old style 3.1s or the new style 3.0? It's a strange configuration I agree.

Off the top of my head I would assume that the standard 3.1 sockets may actually be faster than the C sockets because they are only 3.0, HOWEVER, then I have to take into account that I won't be using the fancy fibre-optic link cable, only a regular USB cable. 

If anyone who knows about this sort of thing could enlighten me that would be so appreciated.
