That Intel SATA port circuit issue was an extraordinarily rare screwup.
So ok, yeah...I said that chips don't just keel over and die mid-life
and you came up with the one counterexample in the history of
the industry :) When I worked in the business in the 80's and 90's
we had a few things like this happen, but they're very rare and
typically don't escape into the wild (as Intel's pretty much didn't).
If a similar problem affected SSDs, they would have been recalled
and lawsuits would be underway.
SSDs are just not that different from anything else.
No special voodoo technology (besides the Flash devices themselves).
