Why do computers start up so fast now?

I remember computers used to take sooo long to start up, that you can press the power button and go make yourself a sandwich. What changed? Hardware got faster obviously, but software also got more complicated and there are more of them to load up no?

SSDs are the biggest contributor as mentioned, but it’s also due to general OS changes in some cases. In Windows for example, they have “Fast Startup” – which realistically is just waking from a sort of hybrid sleep mode. The computer writes a hibernation file then shuts down, when it boots it does so using that file which is faster than a cold boot.

This is the default in almost all laptops, and in some desktops as well. Any time you boot the computer from “shutdown”, it uses this file which is much faster than normal. A reboot operation is more akin to the shutdown from the old days of Windows, with the caveat that the computer starts back up afterwards. This Fast Startup can be disabled too though.
