In The Tech Report's ongoing SSD endurance challenge, three SSDs are soldiering forward. We have reached the thousand-terabyte mark, which is at least five times more than any of the survivors are rated for. These survivors: The Corsair Neutron GTX, the Samsung 840 Pro, and the Kingston HyperX 3K. Technically, the HyperX was able to reach 1PB of written data with performing only 716TB of actual writes, due to compression.

Of course, each of the drives are less-than prestine. The Corsair Neutron GTX 240GB was slowly decreasing in its "life" attribute since the beginning, claiming to be somewhere between 75% and 80% with a fairly linear decline. If this trend continues, the drive will reach "zero" at around 4-5PB of writes. That said, its read speed has substantially dropped from the time between 900TB and 1000TB of total writes, from 500MB/s to just under 400MB/s. Also, this "life" could drop substantially if the drive encounters reallocated sectors (which this model has apparently yet to do).
The other two drives are a similar, remarkably successful story.
The Kingston HyperX drive is reporting itself to be substantially worse off, within the last 10% of its life. That said, even though it claims to be pining for the fjords, it is still working and has only reported a couple of reallocated sectors, those occurring in the last 100TB of writes.
The Samsung 840 Pro seems to still be going strong, although it had more zero or "a couple" of reallocated sectors -- every hundred terabytes yields about 500 reallocations.
As always, this is just our brief discussion of what The Tech Report found out. Be sure to check out their full article for many more benchmarks, tests, and conclusions.
