![]() ![]() Pusin said: “In the near term, we expect to see moderately increased failure rates for this specific subset of 12TB drives, but as we complete the drive migration, we project our fleet’s failure rates will restore to historical norms.”īackblaze customers should be unconcerned because the company’s processes mask drive failures and recovery. Cloud storage and backup provider Backblaze has released a comprehensive report detailing reliability statistics for the hard drives it operated during the whole of 2021, with an interesting finding on its older kit.

The ones used as boot drives in its datacenters seem to be, but perhaps not over time. The Avg Age (Months) column is the average age of all the hard drives of the given hard drive model. For its evaluation of hard drive performance, Backblaze removed 386 drives from consideration that were used for testing or for which it did not have at least. This work involves “things like testing new drive platforms in real workload environments, providing telemetry tools to predict failures, performing ongoing custom adjustments, and employing firmware development and replacement units (RMAs). The Max in Service column is the maximum number of drives ever in service for the given hard drive model. “It’s worth noting that situations like this are not uncommon in our industry and often go unnoticed by the end-users of the services,” Pusin wrote, “as most cloud providers do not inform customers or the public when they experience issues like what we’re describing.” Testing new drive platformsīackBlaze is working with Seagate to understand what’s going on. In 20, the 12TB Seagate drive’s AFR was 2.01 per cent and 1.39 per cent. ![]()
