Hard drives are still expected to store the bulk of that data, meaning cloud storage companies like Backblaze will have to increase capacity by either increasing existing storage density and/or building, or building out, more data centers. Over the next several years, data growth is expected to explode. Keeping lower density drives in service when higher density drives are both available and efficiently priced does not make economic sense.
Backblaze drive report 2018 plus#
That's plus or minus a few months depending on how much we paid for the drive and a number of other factors. The drives we are replacing are about 4 years old. We replaced 3TB, 4TB, and even a handful of 6TB drives with 3,600 new 12TB drives using the very same data center infrastructure, i.e. We use 45 drives of the same model as the minimum number when we report quarterly, yearly, and lifetime drive statistics.Īs noted, at the end of Q3 that we had 584 fewer drives, but over 40 petabytes more storage space.
Quarterly failure rates can be volatile, especially for models that have a small number of drives and/or a small number of Drive Days.If a drive model has a failure rate of 0%, it only means there were no drive failures of that model during Q3 2018.The table below covers what happened in Q3 2018. 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 45 drives (see why below). Hard Drive Reliability Statistics for Q3 2018Īt the end of Q3 2018, Backblaze was monitoring 97,770 hard drives used to store data. In addition, we'll say goodbye to the last of our 3TB drives, hello to our new 12TB HGST drives, and we'll explain how we have 584 fewer drives than last quarter, but have added over 40 petabytes of storage. This review looks at the quarterly and lifetime statistics for the data drive models in operation in our data centers. Of that number, there were 1,866 boot drives and 97,770 data drives. As of SeptemBackblaze had 99,636 spinning hard drives.
