Andy Klein from Backblaze here. We have done some survival analysis (kaplan-meier curves). In our case, we need to have a reasonable number of failures over the observation period to get decent results. You can take a look at some of our work here: https://www.backblaze.com/blog/hard-drive-life-expectancy/ and see if that is what you were expecting.

Yes! Thank you. I've been thinking about scratching this itch myself but it turns out you did already.

In particular the shape of the survival curve interests me -- you hear so many things about exponential here, bathtub there, but ver little data. I will read once I have a spare moment.
