At Backblaze we have built an extremely cost-effective storage system that enables us to offer a great price on our online backup service. Along the path to building our storage system, we have used time-tested technologies off the shelf, but we have also built in-house technologies ourselves when things weren’t available, or when the price….
We recently installed and deployed 45 HGST 8TB hard drives into Backblaze Storage Pod 902 and the drives have recently completed their initial data loading phase. As we have done with Seagate, Western Digital, and Toshiba drives, we tracked the HGST drives during their data loading phase to see how well they performed. Here’s what….
Backblaze Storage Pod 027 has been running 24/7/365 storing customer data for the past 7 years. Pod 027 has served us well, but now it is time to retire. Pod 027 is one of 20 Backblaze Storage Pods being retired. In this group are version 1 and version 2 Storage Pods. They have been removed….
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….
