Due to the fact, that I was curious myself about the results I may get with an Intel NVMe driver, I have installed today the Intel RST NVMe driver v17.11.0.1000 WHQL onto both PCs (AMD/Intel) and made additional benchmark tests thereafter.
You can see the surprising results within the updated post #200.

@all:
Update of the start post
Since my first benchmark comparison tests done in September 2018 are not up-to-date anymore and new benchmark results are available, I have completely updated the start post of this thread.
This will make it much easier for the Forum visitors to find the latest results and evaluations.
Enjoy it!

To make it easier for the visitors to find all posts about the topic "Which NVMe drivers are the best (performance related)", I have merged the related separate threads into this already existing one and hope, that this is ok for you.

@POE_UK
Please add to your most recent post, which NVMe drivers were tested by you.
Thanks in advance!
