QNAP Integrates Backblaze B2 Cloud Storage to NAS Servers - 12:12 PM All of the drives listed were installed during this timeframe. The reporting period is from April 2013 through December 31, 2019. The table below shows the lifetime failure rates for the hard drive models we had in service as of March 31, 2020. We use 60 drives as a minimum as there are 60 drives in all newly deployed Storage Pods. When we report quarterly, yearly, or lifetime drive statistics, those models with less than 60 drives are not included in the calculations or graphs. For example, we have: 20 Toshiba 16 TB drives (model: MG08ACA16TA), 20 HGST 10 TB drives (model: HUH721010ALE600), and 20 Toshiba 8 TB drives (model: HDWF180). There were 195 drives (129,959 minus 129,764) that were not included in the list above because they were used as testing drives or we did not have at least 60 drives of a given model. In both cases, the 0% AFR for the quarter is impressive. If the 8 TB model had 1 (one) failure in the quarter, the AFR would only be 0.40% and the 12 TB model would have an AFR of just 0.26% with 1 (one) failure for the quarter.
On the contrary, both of the HGST drives with 0 (zero) failures in the quarter have a reasonable number of drive days, so the AFR is less volatile. Similarly, the Toshiba 4 TB drive AFR would be 4.05% with just one failure in the quarter.
For example, if just one Seagate 16 TB drive had failed, the AFR would be 7.25% for the quarter. As a consequence, the AFR can range widely from a small change in drive failures. None of the Toshiba 4 TB and Seagate 16 TB drives failed in Q1, but both drives had less than 10,000 drive days during the quarter. In addition, the Q1 2020 AFR is significantly lower than the Q1 2019 AFR which was 1.56%.ĭuring this quarter 4 (four) drive models, from 3 (three) manufacturers, had 0 (zero) drive failures. That is the lowest AFR for any quarter since we started keeping track in 2013. The Annualized Failure Rate (AFR) for Q1 2020 was 1.07%. The table below covers what happened in Q1 2020. For our evaluation we remove from consideration those drives that were used for testing purposes and those drive models for which we did not have at least 60 drives (see why below). As always, we look forward to your comments.Īt the end of Q1 2020, Backblaze was using 129,959 hard drives to store customer data. In addition, near the end of the post, we review a few 2019 predictions we posed a year ago. This outcome looks at the Q1 2020 and lifetime hard drive failure rates of the data drive models currently in operation in our data centers and provides a handful of insights and observations along the way. Of that number, there were 2,380 boot drives and 129,959 data drives.

The full Backblaze report is available here.As of March 31, 2020, Backblaze had 132,339 spinning hard drives in their cloud storage ecosystem spread across four data centers. Of course, we won’t know for another 6 to 8 years if that’s true. The helium is thought to also increase lifespan by reducing said friction. Something else to consider – although it wasn't brought up in the Backblaze report – is that new high-capacity drives are filled with helium to reduce the friction from so many platters spinning in the tight space. That means it can deploy much more capacity in the same space, and the eight-year-old Seagates are headed for recycling. Klein said that in 2023, Backblaze plans to replace older drives with 16TB and larger hard drives. The next closest is HGST, which Western Digital owns, at 0.81% AFR. Western Digital earns bragging rights for the lowest failure rate at just 0.20%. However, Backblaze only has 79 of this model in service, and these drives are used as spares to replace 8TB drives that have failed, Klein noted. In 2022, only one hard-drive model in Backblaze's fleet had zero failures: the 8TB Seagate. You could make a good case that, for us, many Seagate drive models are just as cost effective as more expensive drives," Klein said. Their failure rates are typically not high enough to make them less cost effective over their lifetime. "In general, Seagate drives are less expensive, and their failure rates are typically higher in our environment.
