If SMART gives you the illusion of safety, you didn't understand SMART.
SMART hints *only* the potential presence or occurence of failures in
the future, it does not prove the absence of such - and nobody ever said
it does. It would even be impossible to do that, though (which is easy
to prove by just utilizing an external damaging tool like a hammer).
Concluding from that that not having any failure detector at all is
better than having at least an imperfect one is IMHO completely wrong.
