hard drive failures Hard Drive Stats for Q3 2016: Less is More

[Metatron]

In our last report for Q2 2016, we counted 68,813 spinning hard drives in operation. For Q3 2016 we have 67,642 drives, or 1,171 fewer hard drives. Stop, put down that Twitter account, Backblaze is not shrinking. In fact, we’re growing very nicely and are approaching 300 petabytes of data under our management. We have fewer drives because over the last quarter we swapped out more than 3,500 2 terabyte (TB) HGST and WDC hard drives for 2,400 8 TB Seagate drives. So we have fewer drives, but more data. Lots more data! We’ll get into the specifics a little later on, but first, let’s take a look at our Q3 2016 drive stats.

 

Backblaze hard drive reliability stats for Q3 2016

 

Below is the hard drive failure data for Q3 2016. This chart is just for the period of Q3 2016. The hard drive models listed below are data drives, not boot drives. We only list drive models that have 45 or more of that model deployed.

 

Spoiler

 

A couple of comments on the chart:

 

• The models that have an annualized failure rate of 0.00% had zero hard drive failures in Q3 2016.
• The “annualized failure rate” is computed as follows: ((Failures)/(Drive Days/365)) * 100. Therefore, consider the number of “Failures” and “Drive Days” before reaching any conclusions about the failure rate.

well... i got 2 x 3tb Toshiba's, 1 WD 1.5tb, 3x2tb samsungs and 1 1.5tb samsung and of course a 1tb samsung...  samsungs before seagate bought them.

seems i made the right choice.

Seems that the 8TB models they have bought are doing relatively well. Will be worth seeing how they hold up though.

 

The 6TB WD drives are surprising though.
