I have a laptop with NVMe on which if I setup Win10 to boot without password prompt and no BIOS test, I can have a working desktop from cold start under 2 seconds. I actually hate that kind of speed since if I want to change something in BIOS / have different startup (like OS recovery prompt for example) my F2 / Del / F8 pressing has a lot of misses.
Nowadays startup under 10 seconds is more of a hinder than a gain. My 2 cents
