The slot is an m.2 NVMe Key M, is that correct?  If so, why the SATA m.2 device.  That is Key B + M.

Hi, @lucydrop21 


To add to what wb2001 posted, the HP quickspecs for your 800 G4 DM clearly indicate that only NVMe M.2 SSD's are supported.


Actually the only M.2 SSD's supported for the entire lineup are NVMe.


See page 15.


The only SATA drives supported are the 2.5" variety.
