SSD Endurance Experiment: Data retention after 600TB
 

By far the most telling takeaway thus far is the fact that all the drives have endured 600TB of writes without dying. That's an awful lot of data—well over 300GB per day for five years—and far more than typical PC users are ever likely to write to their drives. Even the most demanding power users would have a hard time pushing the endurance limits of these SSDs.

So far, the MLC drives have been exemplary. Their flash has suffered relatively few failures, and two drives remain completely unscathed. Our lone TLC offering continues to retire bad blocks at a steady pace, but the Samsung 840 Series still has plenty of flash in reserve. Apart from the unrecoverable errors we encountered after 300TB of writes, its performance has been solid overall.
