I would guess that would be the case for the most part these days... I don't think I'd want to use a modern OS on a spinning drive, at least for the OS/swap. Of course, linux (ubuntu) has its' own issues, like the 80+gb ~/.cache/upstart/unity.7.log file filling up the ssd every couple days (still haven't caught it when not full to be able to dig into, annoying all the same).

Though worst from MS on spinning drives has to be using Visual Studio on a web project (or node dev for that matter)... it's painful.
