Sources for "instant croak"?
My sources says the reverse. Being blind to the signs of degradation doesn't make them non-existant (especially if one disables SMART).
Of course, a dead SSD is dead. However, loss in speed is generally an indication that the chips are wearing out, and this is where SMART becomes useful. You can see how much times it failed, how many "full drives" you wrote (MWI and wear leveling/cycles, etc).
Also, samsung 830/840 SSD's are one of the most long-lasting consumer drives, and they are proven
to fail predictably.
