Right, I searched from my phone and the details on the Amazon mobile site aren’t as obvious as the regular one. Sounded good but not what you wanted. I did another informal search and didn’t find anything other than 1 Nvme and 1 m2 sata configuration, same as the one I linked before. I think I found the Asus model you mentioned, might cost more but it’s cheaper than a new motherboard. I wonder a little about latency if the system is trying to access both drives at the same time or even intermittently.
