Over the past year we’ve been releasing hard drive reliability statistics based on the drives we use to store customer data for our online backup business. As of the end of Q1 2015 we had 44,252 hard drives spinning in our datacenter. If we subtract boot drives and drive models with less than 45 drives….
Over the past year or so we’ve covered the virtues and vices of nearly all the different hard drives we use in our Backblaze Storage Pods. From HGST to Seagate to Western Digital hard drives, we’ve charted drive hours, plotted failure rates, reported on drive temperature and more. The one missing brand: Toshiba. We’ve had….
A few months back we published our initial evaluation of 6TB drives, comparing Seagate (model ST6000DX000) and Western Digital (WD60EFRX). Both drives performed well in our evaluation of 45 drives each, but we wanted to see if the results held up as we scaled the quantity of drives. We now have 450 Seagate and 495….
Beginning in January 2012, Backblaze deployed 4,829 Seagate 3TB hard drives, model ST3000DM001, into Backblaze Storage Pods. In our experience, 80% of the hard drives we deploy will function at least 4 years. As of March 31, 2015, just 10% of the Seagate 3TB drives deployed in 2012 are still in service. This is the….
We are thrilled to share the results of a project that has engaged the Backblaze engineering team for the last year: Backblaze Vaults, a major step forward in our cloud storage service’s technology stack. Currently Backblaze stores over 150 petabytes of data and has recovered over 10 billion files for customers of our cloud backup….
Backblaze now has 150 Petabytes of customer data safely stored by our cloud backup service and waiting to be restored by our customers when requested. This customer data is stored encrypted on 980 Backblaze Storage Pods which contain 44,100 data hard drives of sizes ranging from 2 to 6 Terabytes. Each week, new Storage Pods….
It has been nearly a year since we published an update to our Storage Pod design. Over the last few months we have been deploying Storage Pod 4.5, which is known internally as Storage Pod Classic. The reason for the “classic” nickname comes from the fact that Storage Pod 4.5 is derived from our Storage….
Stats Geeks: Now it’s Your Turn. Backblaze Online Backup has released the raw data collected from the more than 41,000 disk drives in our data center. To the best of our knowledge this is the largest data set on disk drive performance ever to be made available publicly. Over the past 16 months, I have….
