Update to Q1 2017: Seagate redeemed?

Update June 8 2017

After some delay, I finally got around to downloading another 9 months of data and rerunning the KM plots. Methods are documented in the first post and won't be repeated here. Note that drive models with fewer than 500 units, and manufacturers with fewer than 200 units are ignored to simplify the plots - you can fix this in the code if you need. 

Images below are available for the closer inspection they deserve at - they really are too detailed to appear here - sorry for the ugly layout here but you can download them or clone the repository if you want a closer look.

Straight to the chase. Here's the drive model survival curve to date:

The newer Seagate ST8000NM0055 is promising excellent longevity although there's only a tiny duration of observation so the initial curves may change with time. 

Also, we haven't tested if this is related…
