I had an ADATA SSD die on me recently after less than 1 month power-on time with negligible write throughput. Tons of reallocated sectors and it failed by refusing any further writes (after having previously caused some unexplained FS corruption a day earlier). (thread)

I bet we'd see wildly different results for different brands, and many deaths well before the specified total drive write endurance. Perhaps a good metric for how good the firmware/FTL algorithm is.

There are plenty of use cases that have this "rewrite one sector repeatedly" pattern - e.g. md-raid metadata includes an event count that basically increases every time the array is written to. I wonder if anyone else has seen this kind of early death and attributed it to this.
