If you are not satisfied with the performance or with the stability of Microsoft’s in-box generic NVMe driver, I recommend to do some benchmark tests with the following NVMe drivers (don’t forget to set a “Restore Point” before starting):
a) 64bit Samsung NVMe driver v3.3.0.2003 WHQL for Win10 x64 (installation has to be forced!)
b) 64bit Micron NVMe driver v2.1.19.0 WHQL for Win8-11 x64 (installation has to be forced!)
c) generic 64bit Phison NVMe driver v1.5.0.0 WHQL for Win8-10 x64
If you don’t know how to force the installation of a suitable, but natively not accepted driver, please read >this< post.
