I have a "not Lexar" 8TB NVMe that I've had for almost 3 years with no trouble. Should I be worried? Or is Lexar just bad?

Incidentally, looks like the price has barely come down on these since I bought.

I'm not personally interested in the tech, but I could see it being relevant if your refrigerator is connected to the internet and you are at the store. You could find out whether to buy more or not.
