OWC Envoy Pro EX via Thunderbolt 2

11201ny said:
Does anyone have experience running a OWC Envoy Pro EX on a Mac Pro 6,1? Since TB2 can theoretically transfer data at 2500 MBps, is should be able to transfer close to it's (real) speed of 730MBps Write / 1000MBps Read.

Anyone do a speed test of this configuration?

The Envoy Pro EX is a USB-C device, not Thunderbolt. You can connect it to the USB 3.0 ports on the Mac Pro, but not the Thunderbolt ports.
 
I have tried to connect the SAMSUNG X5 (and TEKQ Rapide) to a Thunderbolt 2 equipped Mac and the SSD wasn't recognized at all. I guess Apple's TB3 <-> TB2 adapter only delivers power if connected to a TB3-Mac <-> adapter <-> TB2 SSD.
 
ha! while doing some research about TB3 <-> 10GbE adapters, I stumbled upon these remarks:

  • To use this bus-powered device on older Thunderbolt and Thunderbolt 2 computers, it has to be connected to the second Thunderbolt 3 port on another self-powered Thunderbolt 3 device. If connected directly to the Thunderbolt 3 to Thunderbolt 2 adapter, bus-power is insufficient. A possible setup might look like this: TB2 Mac with macOS 10.13.4 or above > TB3 to TB2 adapter from Apple > self-powered TB3 device with two TB3 ports > TB3 10G adapter.
 
My (simple minded) understanding is that these drives are limited by lanes, with reduces the speed to something like 700 MBps?
