It&#x27;s fun to see this data come out. I did some of the early reliability tests for these devices. At the time, Google hadn&#x27;t publicly announced that we were using SSDs in the data-center so there wasn&#x27;t really an opportunity to publish or talk about it.<p>The most surprising thing to me was the correlation between age and RBER.<p>I would not have guessed that normal aging would play a significant role in reliability. It would be fun to understand what is happening there.
