Where did you see that the 840 is still going error-free? It says that the 840 maxed out it's reallocated sectors at around 900TB and veered into a ditch right before the petabyte threshold.
It'd be interesting to run these same tests on enterprise grade drives as well.
Edit: You meant that the 840 Pro is still going, I see.
