Thank you for all of that information. Not sure but it looks like the much coveted USB adapter does not support the M.2 MVNe version, at least in the description it only claims support for M.2 NGFF type pcie cards. I am going to call them, likely they are working on one to be released soon. I think NVMe is the newest M.2 pcie technology, so it makes sense that it is very difficult to find. The other PCIe cards for internal use do support the NVMe pcie interface. Your help is much appreciated. I found 2 new sites that I had not looked at before and for this I am grateful! Cheers.

these first 2 are the usb version and description that you are looking for. i am unsure of your location, the prices are in u.s. dollars.
