Endurance experiment writes one petabyte to six consumer SSDs

crookedvulture (1866146) writes "Last year, we kicked off an SSD endurance experiment to see how much data could be written to six consumer drives. One petabyte later, half of them are still going. Their performance hasn't really suffered, either. The casualties slowed down a little toward the very end, and they died 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. While the sample size is far too small to draw any definitive conclusions, all six SSDs exceeded their rated lifespans by hundreds of terabytes. The fact that all of them wrote over 700TB is a testament to the endurance of modern SSDs."
