[Avid-L2] Mac USB 3.0 or 3.1 PCIe Card?

 

I've tapped my local heros and there is a CalDigit Card and there is a Sonnet 4 port card.  The Cal Digit has 2 USB Type A connections, a USB type C connection and an Esata connection.  The Sonnet has 4 standard USB 3 Type style connections.  I've googled and USB 3.1 has double the speed plus enhanced power on the cable.  I've been running one of the Sonnet cards on a MacPro 2010 at work and it handles our Graid etc... USB 3 needs.

So given I have a mid 2012 MacPro 12 core 2.66Ghz and an Cyclone Microsystems Expansion chassis with 2 available 4 lane slots will that configuration even allow me to take advantage of the USB 3.1 speed boost?  The Expansion chassis houses two Titan X GPUs and a 1600 watt power supply.  The chassis is connect to the MacPro 16 lane slot. 

I think the Sonnet will handle my USB 3 connection needs for the current crop of drives I deal with but would that be a short sighted purchase.  I'm assuming the USB 3.1 will throttle back it's speed if plugged into a USB type a port but I'm just assuming.  I've read the future of USB 3.1 is more for mobile and laptop devices but what does this collective brain trust think?  TIA
