Nvme expansion drive terribly slow

Hello -

I purchased a 2tb Mushkin Pilot-E nvme drive for my AW R10.

I have tried a usb-c external enclosure, and I’ve tried a pcie expansion card in slot 4. 

The speed is AWFUL. About 225/175 MB/a on the R10 in either config, but on my MacBook Pro (Intel), the drive maxes out at the enclosures max speed 1000/1000MB/s. 

Is this an AMD thing? I have the 5950x on b550a mobo. Drive works fine on Intel, and both methods of interface on the Alienware are similar speeds (slooooooow). I contacted the external enclosure maker and they refunded me, but I want to get this drive working. 

Thoughts? Thanks.
