Just read what I wrote earlier...
There was a link to test of NVMe drive in AHCI and NVMe mode in my post.
So, belive what you want.

Well I do believe that NVMe is faster, but idk in one video on YT I saw/heared on one channel (was it NCIX, Linus or ASUS I don't know, can't remember right now) that what he wrote for games. :v

Sequential speed on AHCI is bigger than you think
Comparison of NVMe drive in both AHCI and NVMe mode : LINK.

To me 15% reduction is a lot (considering you pay for NVMe).
But you are correct in not seeing much difference between them in OS drive application.

PS. Latest drivers can be downloaded from manufacturers websites. Not much different than AHCI drivers really.

Keep in mind - not all NVMe drives are equal, just as not all SSD's are equal.

So WD Black NVMe M.2 SSD, would be good investment?

For content creation (saving/loading files to/from it specifically), absolutely.  For anything else, no.

When you said AHCI I was thinking via SATA.  That's usually what people mean.  Comparing modes isn't really necessary.  Obviously you'd enable NVMe if you have a drive capable of it.

 

When you look at an Intel 600p NVMe drive vs a Samsung 850 Evo SATA drive, you'll see significantly lower 4K read speeds, despite the Samsung one being cheaper.

 

I should mention that while 4K read speeds are a good measurement for how your OS will run, there are diminishing returns, especially when you get past 35MB/s.

So u are saying that I should use NVMe for OS and large files, while SATA SSD for games ? ^-^
