Backblaze:

It was one year ago that I first blogged about the failure rates of specific models of hard drives, so now is a good time for an update.

At Backblaze, as of December 31, 2014, we had 41,213 disk drives spinning in our data center, storing all of the data for our unlimited backup service. That is up from 27,134 at the end of 2013. This year, most of the new drives are 4 TB drives, and a few are the new 6 TB drives.

Wow. That does not look good for Seagate.
