I'm turning to the expertise of this thread after bumping my head for most of the day.
I've tried to post this in the proper section: iMac, but I feel this more of a general MacOS-SSD-protocol issue.
Long story shot: have late 2015 iMac (17.1) with 24GB Apple SSD and 1TB Samsung 850 EVO SSD configured as a Fusion drive (bought a used iMac that came in this config). Want to break Fusion drive and install new 1TB drive in 24GB SSD NVMe connector, to end up with two separate drives, without 'Fusion'.
Reached for OWC's Aura Pro X2 that on the fist page lists as compatible. But just before pulling the trigger saw this:

My iMac is the one bottom left with the fat, red X. Both older AND newer iMacs list as compatible.
Called OWC technical support (not sales) and they took the time to investigate and replied later via email: "won't work". This baffles me.
The physical connector is the same: 12+16 Apple style. The 17.1 iMac used an AHCI drive originally. Is this the issue? OWC didn't even mention this—they didn't know why the chart above looks like that, but they don't have confidence to go against it.
Found a great resource at Beetstech, but they also only list AHCI as compatible and they sell used Apple drives for $$$.
I'd appreciate any thoughts on what's possible here. A fallback that seems 100% is a used SSUBX from Beetstech, but I'll get a faster, larger and cheaper from OWC if the Aura Pro X2 actually works.
Thanks
