Endurance experiment kills six SSDs over 18 months, 2.4 petabytes

crookedvulture writes: Slashdot has previously covered The Tech Report's SSD Endurance Experiment, and the final chapter in that series has now been published. The site spent the last 18 months writing data to six consumer-grade SSDs to see how much it would take to burn their flash. All the drives absorbed hundreds of terabytes without issue, far exceeding the needs of typical PC users. The first one failed after 700TB, while the last survived an astounding 2.4 petabytes. Performance was reasonably consistent throughout the experiment, but failure behavior wasn't. Four of the six provided warning messages before their eventual deaths, but two expired unexpectedly. A couple also suffered uncorrectable errors that could compromise data integrity. They all ended up in a bricked, lifeless state. While the sample size isn't large enough to draw definitive conclusions about specific makes or models, the results suggest the NAND in modern SSDs has more than enough endurance for consumers. They also demonstrate that very ordinary drives can be capable of writing mind-boggling amounts of data.
