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.
