Yeah that's not a bad idea. It's still a big context switch to dual boot tho. Also dumping your entire machine's RAM to disk on an SSD seems questionable for the lifespan of your SSD. That's a huge amount of writes, especially if you're dual booting a few times a day. But maybe it wouldn't matter? I haven't measured how much of an impact that would have.

And in my case, it wouldn't work because I need to be able to record a Linux environment but record / edit videos in a Windows environment, so both OSs need to be running at once.

I think the SSD write cycle fears are overrated. I might be wrong. I've been doing it for years with extremely cheap Kingston SSD's. I also need to edit videos, not too often, hence I need windows. Switching takes like 6 seconds, most of the time from waiting for the grub menu. It might be worth to try out the workflow.
