Which nvme drive I should buy?

I’m thinking about upgrading my NVMe drive to larger and better one. I was thinking about Samsung 980 or Samsung 980 PRO. But I’m thinking if paying more for speeds that probably I can’t use is not a good idea. So are Qubes is able to take any advantage from 980 PRO?

When you said you can’t use the ‘speed’ does that mean your hardware only support pcie 3? if it’s fit with the wallet, why not.

I never like samsung parts, no even bother to look it until now.
Consider use firecuda 530, it has 5k++ tbw while 980 pro only 1k++ tbw.

And if the budget not fit, you could go with firecuda 510, i use it!
or maybe teamgroup disk.

No advertising here, just personal preference.

I’m asking since I’m not aware what are possible be bottlenecks here. Is this only a pcie version that can reduce the speed or also the drivers or some block device handling in the system? I remember that I read not so long ago that MS finally shipped some feature that allow using full speed disk transfer while gaming.

based on my latest benchmark here, I think yes, but not sure.
