Interesting. I'm looking at the Crucial MX500 in either 2x1TB or 1x2TB configuration. They appear to be "TLC" drives rather than QLC or SLC, but I would imagine that both configurations would have more or less the same amount of cells. > Which is to say that if you haven't actually tested *your workload* > on > it, then there's some risk.
