(TechReport) SSD Endurance Gets Interesting at 300TB

Update 11/26/2013 @ 11:20pm Allyn weighed in, particularly about the Samsung drives. One thing that he notes (as does Tech Report in the original article) is that Samsung might just be more severe in its reporting of errors. For instance, he believes that it is just about impossible for SSDs to write 300TB of data without ever seeing a flash read error. Regardless of what they report, each of these drives keep on ticking. It is "significantly beyond the expectations of a consumer (non-Prosumer) SSD".
The Tech Report has been testing a batch of SSDs for their life expectancy over several months now. Results have been fairly interesting: drives were relatively stable even up to 200TB of cumulative writes; some drives even got faster. Now they have passed the 300TB threshold and we are seeing certain drives hit some harsh realities. As Scott Wasson said in a tweet:
Our endurance experiment has finally hit the limits of one consumer SSD: http://t.co/zxw7mRkT2K

In all, though, even the TLC offerings have surpassed reasonable expectations. Consumer drives are designed for consumer machines and will likely take decades to reach the hundreds-of-terabytes order of magnitude for today's usage.

It makes me wonder exactly how over-provisioned enterprise hardware is if these, consumer, parts have such high reliability.
