Backblaze Releases Its Q1 2017 HDD Reliability Results

3 posts in this topic

As with the last time we looked at it, the annualized failure rate (annualized failure rate is computed by ((Failures)/(Drive Days/365)) * 100) has crept up slightly again, this time to 2.07%, or just over 1,700 drive failures out of over 82,000. Again Seagate has the highest annualized failure rate of a single drive, ST4000DX000, though it was 7.51% this go round versus the nearly 20% we saw in the same model number last time we looked at the results. The drive with the least amount of annualized failure was the HGST HMS5C4040ALE640 with just 0.64%. Failure in this study is defined as 1) The drive will not spin up or connect to the OS. 2) The drive will not sync, or stay synced, in a RAID Array. 3) The Smart Stats used show values above Backblaze’s thresholds.

BackBlaze makes their raw data file available for download. You should be able to extract that data with a bit of scripting.
