Backblaze Hard Drive Stats for 2016

Backblaze has recorded and saved daily hard drive statistics from the drives in our data centers since April 2013. At the end of 2016 we had 73,653 spinning hard drives. Of that number, there were 1,553 boot drives and 72,100 data drives. This post looks at the hard drive statistics of the data drives we monitor. We’ll first look at the stats for Q4 2016, then present the data for all of 2016, and finish with the lifetime statistics for all of the drives Backblaze has used in our cloud storage data centers since we started keeping track. Along the way we’ll share observations and insights on the data presented.
