So I am updating my PC with Asus rog Maximus ix extreme z270 Mobo and I have a 512gb pm961 Samsung oem drive and I am planning on buying the 970 pro nvme and I want to set up raid with those drives, how do I do that in Mobo setup, I read that I have extract Intel rst drivers and install them to windows so windows install will recognise the drives but I also believe the Samsung drivers work better and how should I extract Samsung drivers from the .exe file and load it into windows installation for windows 10, thank you.

Do you possibly mean you want to setup a different kind of raid for fault tolerance? Any kind of SSD or M.2 drive gets faster with size (512GB faster than a 256GB) so maybe you might just want to go for the next bigger version.

Since your system isn't exactly heavy on the PCIe lanes front, you realise this presumably means running your GPU at 8x rather than 16x PCIe, right? Not that that incurs a real penalty for current hardware, just saying..

I have come to the understanding that raid with the m. 2 does not provide any real-world benefits apart from some benchmarking, I will be using the i7 7700 k and I believe it has 16 pcie Lanes and also off the understanding that the DMI is almost fast but only slow by a few nanoseconds when compared to directly connected to the cou via pcie ratherr than to the process via dmi, but my main question was lot of YouTube videos show about only installing the Intel rst drivers for Windows to recognize the nvme raid but Samsung provided drivers are faster than the speed of Intel rst drivers which I'm not sure about , so while trying to install Windows onto this m. 2 how do I get the Samsung INF files to be loaded at the insulation screen.

Samsung presumably does not supply drivers for third party RAID.

You have 16 PCIe lanes, and the equivalent of 4 PCIe lanes for DMI. If you hook up one m2 drive, you (can) saturate this DMI bus. When hooking up a second m2 drive, as you mentioned in your opening post, the lanes for that must come from somewhere, depending on how your motherboard is wired. I'm assuming you have a dedicated graphics card that by default gets all 16 available PCIe lanes.

Well I guess then x299 chipset is the only way to go forward for better performance with the nvme drives, BC head on the z270 motherboard has 24 Lanes but I guess they only go into 4 PCI Lanes in DMI so I guess these 270 is not the correct chipset for multiple drives. I am also of the understanding that the z270 chipset is more than enough for regular day-to-day use and for regular gaming an extra 99 not really needed unless one has specific need, correct me if I'm wrong.

Also technically if I use the gpu in x8 mode and then use the other x8 for a single nvme in x4 and a USB reader for high speed for VR gaming I should be good as even in x8 not much is lost in gpu performance, correct me?

And why the need for the RAID 0?
Aside from synthetic benchmarks...you see zero benefit.
It might even be a teeny bit slower.
