I did some digging in the days of yore just because I was curious about how these things worked, and I found absolutely nothing on how people make these things work. I'm really amazed that unbranded 512GB NVMe drives doesn't randomly eat my data at this point, yet I still can't trust any of these drives w/o file level checksum patrols. So, instead I buy Samsung 9xx drives and use them.
