I have an optane drive with the kernel on it, instant boot!

How does that work? It loads kernel from drive to ram?

Isn't windows fast boot something like that (only slower, depending on ssd)? It semi-hibernates, stores kernel part of memory on disk for faster startup.

This one would have behaved more like suspend to RAM. In suspend to RAM, the RAM is kept powered, while everything else is shut down. The recovery would be near instant, since all the execution contexts are preserved on the RAM.

Optane was nearly as fast as RAM, but also persistent like a storage device. So you do a suspend to RAM, without the requirement to keep it powered like a RAM.
