Mixing M.2 SATA with M.2 NVMe on P50

2019-12-01, 18:28 PM


My refurbished P50 came with a Toshiba M.2 SATA (256GB) which has the Windows 10 image.  I want to add a second M.2 drive (500GB) and for this purchased a Samsung 970 Evo Plus NVMe M.2 (V-NAND SSD), on which I'll install Fedora 31. I have the correct tray for the NVMe, and the drive does appear in the bootllist.

The P50 Hardware Maintenance Manual on page 69, "The M.2 solid-state drive slots support both SATA solid-state drive and Non-Volatile Memory Express (NVMe) solid-state drive. If you install two M.2 solid-state drives, ensure that the two M.2 solid-state drives are of the same type."  However, I've read several posts related to adding a second M.2 drive, and a few seemingly knowlegable people have said you CAN mix the architectures. 

Can anyone say definitively why the docs say not to mix the drives?

It could very well be that it works, but is simply unsupported by Lenovo because that particular configuration wasn't tested when the P50 hardware was being qualified.
