The article states as much but to sum it all up as just that is leaving most of the good stuff out.

Perhaps the most interesting part of the experiment series has been just how much longer these cheap drives with tons of writes have been lasting compared to the testing requirements (especially with so much past write endurance on the one just now starting to exhibit trouble). Part of the impetus for the series seemed to be lots of claims on how quickly to expect massive problems without any actual experimental tests of consumer drives to actually back it up. Of course n=4 with 1 model of 1 brand drives but it's taken ~20x longer than some common assumptions to start seeing problems on a drive at 5x its endurance rating.
