Kingston HyperX 3K 240BGB
Obviously, the limited sample size precludes drawing definitive conclusions about the durability and reliability of the individual drives. The second HyperX's against-all-odds campaign past 2PB demonstrates that some SSDs are simply tougher than others. The important takeaway is that all of the drives wrote hundreds of terabytes without any problems. Their collective endurance is a meaningful result.
Samsung 840 Pro 256GB
The SSD Endurance Experiment represents the longest test TR has ever conducted. It's been a lot of work, but the results have also been gratifying. Over the past 18 months, we've watched modern SSDs easily write far more data than most consumers will ever need. Errors didn't strike the Samsung 840 Series until after 300TB of writes, and it took over 700TB to induce the first failures. The fact that the 840 Pro exceeded 2.4PB is nothing short of amazing, even if that achievement is also kind of academic.
