Yes SATA III and probably good cards, OWC make nice stuff, but I'd have a preference to use a Samsung SSDs not OWC SSDs with them, like a Samsung SSD 860 EVO.. and get a large capacity one (which gives better performance and just fantastic wear life).

Sonnet also make nice SATA III adapters: https://www.sonnettech.com/product/tempossd.html

Yes that all SATA III aka SATA 6 Gbps. OWC and Sonnet talk SATA speeds so their "6" in the description means SATA III.

SATA I == 1.5 Gbps
SATA II == 3 Gbps
SATA III == 6 Gbps

I was having network dropouts while trying to edit this poset and the post above, so see additional comments that were added.

Well then, that's most informative. You sound more like an I.T person than an Audio Engineer! LOL

OK, I just called OWC to return my SSD order which included the sled into the Mac Pro. I will go with your advice on the Card that I can add my own SSD to it. It makes more sense than the all in one NVMe PCIe Card I was looking at.
Thank You for your input!
Cheers!
