WD Blue SN550 NVMe SSD or a Sandisk Ultra M.2 NVMe 3D SSD?
It looks like those two drives benchmark very similarly, so either one would be a great choice for a boot drive.
Specs look identical across the drive sizes I checked.. Looks like the same drive to me. WD bought Sandisk back in 2016 I believe. Treat them as though they're the same.
