Aparently a laptop with 2080 notebook + 970 evo ssd can run the Unreal Engine 5 demo at 1440p, 40+fps. It doesn't require a super fast ssd at all. Confirmed by Epic China.

Epic China is savage lol, directly from the mouth of Epic China engine tech lead...
1) Demo currently runs at 1440p/40fps on his laptop with 2080 and NVME SSD, it runs in the editor, assets aren't cooked in editor so a release build will likely run better.
2) Lumen(GI) has a much higher FPS cost than Nanite(Geometry) so the demo is very much GPU bounded.
3) If you do a rough calculation on paper, assuming two triangles(in practice one is usually the case) per pixel, at 1440p the bandwidth requirement for geometry streaming is measured in term of megabytes... so a very fast SSD is not necessary.
