M.2 nvme sata visual difference.

I think he is just retired. He’s gotta be in his late 60s.

Still, it's easy money. I can't imagine why he'd pass that up unless he thought the book was too difficult to write or it wouldn't sell well.

@Diggs The whole problem with that system was not because it was"Optane" memory. Optane is simply a fast kind of chip. HOW it is interfaced is the issue. That system was set up with a 16GB buffer on the SATA drive. The buffer has to be turned on or off in BIOS or Windows and can only be done if the drive is present. Chances are once you disabled the buffer both of the drives mentioned in your OP would have worked. A buffer is yet a THIRD option for M.2 slots and only works if the chipset supports that function. Most don't.

I'm still trying to fully understand that system but it had RAID turned on in the BIOS so I assume that the NVMe was working in RAID with the 2.5" SATA drive. With RAID turned off I couldn't get it to boot except using the 16 GB NVMe as the primary boot drive. I may revisit that machine at some point as the geek in me is peaked. (Right now it is running Linux Mint xfce entirely off the 16 GB NVMe. I needed another Linux machine on the bench.)
