HDD Warning when game's running on a SSD

For those who don't know, AC: Shadows has a warning when you try to run in on a HDD because it will run poorly. That's fine, what I don't understand is why am I getting a HDD warning if my game is installed in my main drive (which is a Kingston SSD). I've played many other games instaled in this SSD and never had loading issues like I'm having with Shadows (even playing with everything on low).

My main concern is that, somehow, the game is interpretating that I'm on a HDD and then acting out. Did anyone experienced something like this?

UPDATE: It seems like it was some weird stuff with the game files. I've verified them and now the warning is gone and the loading times are normal (close to what other games are).
