In 2013 an experiment to test the endurance of SSD consumer drives by writing 6 PBytes onto them was launched. They are now one petabyte into the experiment. The performance is the same. The casualties slowed down a little toward the very end, and they ceased to function in different ways. The Intel 335 Series and Kingston HyperX 3K provided plenty of warning of their imminent demise, though both still ended up completely unresponsive at the very end. The Samsung 840 Series, which uses more fragile TLC NAND, perished unexpectedly. It also suffered a rash of cell failures and multiple bouts of uncorrectable errors during its life. The sample size is too small to draw any definitive conclusions. All of the six SSDs exceeded their rated lifespans by hundreds of terabytes. The fact that all of them wrote over 700 TByte is a testament to the endurance of modern SSDs.
