We look at the hard drive failure rates for the data drive models in operation in our data centers in 2018 (now totaling over 750 petabytes and 100,000 drives). In addition, we’ll see how the new hard drive models we added during the year did, including our 12 TB HGST and 14 TB Toshiba drives.
As of September 30, 2018 Backblaze had 99,636 spinning hard drives in our data centers, which now includes a large number of 12 TB drives. Here’s our latest report on how they’re all doing, and a brief look at the direction we’ll be heading in the future.
As of June 30, 2018 we had 100,254 spinning hard drives in Backblaze’s data centers. Of that number, there were 1,989 boot drives and 98,265 data drives. This review looks at the quarterly and lifetime statistics for the data drive models in operation in our data centers. We’ll also take another look at comparing enterprise….
Does the promise of helium-filled drives prove to be real? In this post we compare the performance of 19,065 Seagate and HGST helium hard drives vs. 24,281 Seagate air-filled drives. What do the numbers tell us?
For the most recent Hard Drive Reliability Statistics, as well as the raw hard drive test data, visit Hard Drive Data and Stats. As of March 31, 2018 we had 100,110 spinning hard drives. Of that number, there were 1,922 boot drives and 98,188 data drives. This review looks at the quarterly and lifetime statistics….
Starting in 2013, Backblaze has recorded and saved daily statistics from all the hard drives in our data centers. As of the end of 2017, we had 93,240 spinning hard drives and 88 million statistical records totaling 23 GB of data. Here is the summary of our findings for 2017 based on that data.
In this update, we’ll review the Q2 2017 and lifetime hard drive failure rates for all our current drive models. We also look at how our drive migration strategy is changing the drives we use and we’ll check in on our enterprise class drives to see how they are doing. Along the way we’ll share our observations and insights and as always we welcome your comments and critiques.
In this update, we’ll review the Q1 2017 and lifetime hard drive failure rates for all our current drive models, and we’ll look at a relatively new class of drives for us — “enterprise.” We’ll share our observations and insights.
