Well, 1) it hardly matters since the point is that excessive disk access by an OS when, essentially, "nothing is happening" (opening the start menu, say) is a bad sign for generally giving-a-shit about performance and spinning rust just exposes the error, 2) they pushed Win10 upgrades on a bunch of well-performing spinning rust Win7 machines back in the middle of 2015, not 2020, immediately making them much worse, 3) most normal home users don't replace hard drives, don't replace their computer very often, buy the cheapest thing they can aside from that they think higher number = better and are often up-sold a large (=spinning rust) drive they don't need and can be up-sold because they buy them at real stores (yes, really), and only very recently did SSDs mostly displace magnetic platters on base configurations of cheap mass-market desktops. I guarantee a high percentage of home users are still booting off traditional HDDs, yes, even in 2020, and they're exactly the same sort not to have been able to figure out how to not upgrade to Win10.
