I feel for the subjects of our SSD Endurance Experiment. They didn't volunteer for this life. These consumer-grade drives could have ended up in a corporate desktop or grandma's laptop or even an enthusiast's PC. They could have spent their days saving spreadsheets and caching Internet files and occasionally making space for new Steam downloads. Instead, they ended up in our labs, on the receiving end of a torturous torrent of writes designed to kill them.
Talk about a rough life.
We started with six SSDs: the Corsair Neutron GTX 240GB, Intel 335 Series 240GB, Samsung 840 Series 250GB, Samsung 840 Pro 256GB, and two Kingston HyperX 3K 240GB. They all exceeded their endurance specifications early on, successfully writing hundreds of terabytes without issue. That's a heck of a lot of data, and certainly more than most folks will write in the lifetimes of their drives.
The last time we checked in, the SSDs had just passed the 600TB mark. They were all functional, but the 840 Series was burning through its TLC cells at a steady pace, and even some of the MLC drives were starting to show cracks. We've now written over a petabyte, and only half of the SSDs remain. Three drives failed at different points—and in different ways—before reaching the 1PB milestone.
We've performed autopsies on the casualties and our usual battery of tests on the survivors, and there is much to report.
I posted this in the hardware hangout seeing how people in this forum would be the most interested in these SSD 1PB stress test. It was quite an interesting read.
