One thing I know, is that mechanical disk drives have suffered a very big drop in performance in windows 10. I've asked this question several times, "Why would an OS need an SSD to work normally and be responsive when it was already fast without SSD some years ago", and I often get responses like I don't know how computers work, that win10 takes advantages of SSD and that it cannot work well on old techs. Even when you have a high amount of RAM and use a HDD, it's still slow. I'm still looking for a decent filesystem or kernel developer to answer that question with a good enough explanation, because to me, I'm either stupid, or there is negligence or some attempt to increase sales of SSD. Maybe windows now uses SSD as some sort of "secondary RAM", and thus it will never be fast with a HDD. I mean, linux desktops seem to still be fast enough with mechanical HDD.
