Those drives didn't fail to running out of write cycles -- they simply wouldn't have had time to do that by now. They failed because SSD's are still quite new devices that haven't seen the kind of decades of slow improvement like most other consumer hardware. Most SSD crashes are because the firmware managed to corrupt something, and thus you can fix most failed SSD's by reflashing their firmware, assuming the drive has a method of doing this without special equipment. (doing so would, of course, erase the entire drive)
