Actually, any of us who really tried could probably come up with a dozen examples--more if we've been around for a while.

These are excellent examples of failure causes for electronics, but they are
not counter-examples. They're unrelated to the discussion about SSD
early lifetime hard failures.

That's really optimistic. For all we know, these problems are the latest incarnation of something like the bulging capacitor plague circa 5 years ago. Some part that is unique to the SSDs other than the flash cells that there's a giant bad batch of.

I think your faith in PC component manufacturing is out of touch with the actual field failure rates for this stuff, which is produced with enormous cost cutting pressure driving tolerances to the bleeding edge in many cases. The equipment of the 80's and 90's you were referring to ran slower, and was more expensive so better quality components could be justified. The quality trend at the board and component level has been trending for a long time toward cheap over good in almost every case nowadays.
