I've lost 2 M2 drives the first was 2TB Samsung 970 Evo which exceeded it's write endurance limit. Either due to firmware or me writing too much I'm not sure. The other M2 was a smaller Gigabyte drive that had some hardware failure.

My new drive is a 1TB Samsung 980 Pro which has a write endurance of 600TBW so if I wrote 1.5TB a day it would last just over a year. I don't know how much endurance the drive in a Mac Mini has but I can't imagine it is any better than that. I would not want to write so much per day to the systems internal drive if it is not easily and cheaply replacable.
