Answer:

Do you think I should ask for 2x NVMe and no SATA then? can my motherboard hold 2x NVMes?
Motherboard: Gigabyte H410M S2H 1.0 LGA1200 Board

I mainly want it for gaming, I’m okay with bit of loading time or longer time rendering but I’d prefer not stuttering during games or sudden FPS drops and things like that.

What do you suggest I do? I guess I am not going to get any HHD at all and go full SSD, but which ones should I get? I had already told them to replace my 250GB SSD NVMe with a 1TB one, maybe I can split that into 250GB for OS/etc, and 750GB for programs, then another 1TB SSD for games/shadowplay? but the second SSD is the one im not sure if I should ask for Gen3 or SATA

Any advices on that? I was going with SATA thinking I cant have anymore NVMes on my board from the posts above.

Don’t split the OS and programs into 2 partitions. Serves no purpose.

The M.2 port on that motherboard is only PCIe 2.0. And only one of those.

In a game system, the difference between SATA III, PCIe 3.0 and PCIe 4.0?
Blink, and you miss the difference.

Bottom line:
1x NVMe drive, and maybe 1 or 2 SATA III SSD.
You’ll see ZERO difference.
