Hey collective Mac Pro hive mind.

I'm trying to expand on the practical use of my Amfeltec Squid M.2 adapter. I currently run 4 M.2 SSDs on there. I used to run them in RAID 0, but realized the 6000+MB/s wasn't really doing anything practical for my workflow. Even as I work with editing multiple streams of high bit-rate 10-bit 4K video, I've found that the speed of one M.2 SSD handles it fine. So I've found system speed is quite a bit faster overall by dividing the 4 SSDs on the card to different uses (one for OS, one for source media, one for media cache & renders, e tc).

I use the last drive on their for media exports, but it's not really necessary. I'm interested in adding a USB 3.1 Gen 2 port to my Mac Pro. Does anyone know of any M.2 to USB 3.1 Gen 2 adapter out there? I can't seem to find one, but would love to slide a card like that into one of the slots and provide one of these ports. Unfortunately, all my PCI slots are completely full.

I can only find M.2 to SATA port adapters.

try a google image search for m.2 usb 3.1. While not at the top of the list, it looks like there are a couple of options. Although they are not specifically m-key, they should be x2 compatible options.

Thanks guys! Yes, I've been finding a lot of what Synchro3 linked, but after scrolling through what HandHeld linked, I think I found what I was looking for:
https://diarts-tech.com/product/1-port-internal-usb-c-usb-3-1-gen-2-10g-m-2-card/

It seems like the Asmedia ASM2142 is supported in MacOS but I need to research further. Unless you guys can confirm such from your knowledge? Thanks for your help!
