Respectfully, I disagree. I have a gaming PC with tons of Samsung SSDs, none make this noise. My MM 2012 has a Samsung EVO, no noise. Even folks on this forum have said their MM2018s don't have this noise. I think it is luck of the draw based on mfg tolerances. That is why when you buy gaming PC parts, it is recommended to research incidence of coil whine first. Some GPUs are more prone to it than others.
The disappointing thing, IMHO, is that Apple has always been the "no tolerance" company when it comes to expected working behavior. Their reply to me feels like I was chatting with MSI or Dell.

The problem with coil whine, to me as a gamer, is that it is very distracting. It isn't the "same" frequency or harmony over and over like read/write on a spinning HDD. It varies in both how loud it is and the type of noise it makes is always different. So it is more distracting, at least in my opinion, than the sounds that my gaming PC makes which are more rhythmic. Also, FWIW, I can hear the Mac Mini coil whine over a gaming PC with a massive Noctua cooling system, 3 case fans, a standard HDD reading/writing, and a EVGA massive PSU fan.
