Backblaze has releases a new listing of HDD failure rates for Q3 2016. They replaced a lot of 3TB with 8TB HDDs and had pretty good results it seems.

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.
