Given enough writes, any SSD will eventually fail.

As a related anecdote, I did some stress-testing on a ZFS filesystem with two Kingston NVMe SSD-s in mirrored configuration and at one point I got two random read errors on one drive, which subsequently got corrected by ZFS.

Silent failures might not be the best phrase to use for these situations, but ZFS does let you know that corruption has taken place and you have to acknowledge that message for it to disappear.

If the SSD controller isn't bugged, lifetime write limits don't result in silent data corruption; they just result in errored writes and inability to persist new data. Apple may have decided to only qual and sell SSDs that they've tested to failure, rather than throwing darts at random.

It's not clear to me if you're describing silent data corruption or detected data corruption (at the controller level), but either way Apple isn't selling Kingston NVMe SSDs; they have their own SSD controller and vendor the raw flash.
