No they just enter lower power states and keep everything in RAM. I don't even have a swap and it works fine.
Sorry maybe I'm not explaining what I want to very well.
On the Mac it will suspend to RAM but also dump to an image file at the same time. If the mac runs out of power it will later restore from the image once power is restored.
That's possible on Linux using hybrid-sleep and suspend-then-hibernate but they require a swapfile.
I haven't yet found a way to have a swapfile without allowing that swapfile to be used for virtual memory too. I worry that virtual RAM will eat my SSD.
How often do you upgrade your drive? If you expect to change it sometime in next 5 years or so, I wouldn't worry about using swap on SSD at all.
To be honest I hadn’t really considered that. I’ve never actually upgraded an SSD in a laptop.
I guess it may be more the thought that it will kill the SSD than the reality but it’s still something I’d prefer to avoid if there’s a solution.
I'm fine with having a swapfile but I don't want it used for anything other than Suspend-to-disk. i.e. I don't want the SSD being hit with multiple writes caused by VM.
