Very interesting, thanks for the details. You can check your pagefile settings by opening This PC > Properties > Advanced System Settings > Advanced (tab) > Performance (section) > "Settings..." > Advanced (tab) > Virtual Memory (section) > "Change..." (my god I just realized how many levels deep this is buried lol). Having it on the SSD is optimal for performance but will eventually lead to higher wear levels, particularly if you operate with your RAM nearly full most of the time.
I just had a look at my own drive out of curiosity and it reports 0 as the unexpected power loss count, which I find very interesting because I know for a fact that I've had many crashes and improper reboots, so if that isn't what triggers it (evidently), now I'm really wondering what does. I did some looking and it appears to be similar to what I said above, but with some added caveats. It sounds to me like it only counts an event if it was in the middle of trying to write something when power was lost. If it's able to handle the situation, either through internal power backup, not actually losing power at all even given a reboot, or simply by not being busy in that moment, it wouldn't record an event.
Given that new insight, I can't imagine why your drive would be reporting 9 events. If my system with all the crashes it's been through hasn't triggered one, yours, with what sounds like has been a more stable life, definitely shouldn't have. With that said, simply having that number isn't inherently bad as far as I know. I would recommend keeping an eye on it, maybe just check it once a month or something. If it continues going up, then something is likely wrong and deserves further investigation, but if it hold steady, I wouldn't concern myself with it. While it does seemingly indicate a problem, I can't imagine why or how it happened, and if you aren't experiencing any issues (system instability, data loss, etc.) then there isn't much reason to look into it in my opinion.
