Backblaze Hard Drive Stats for 2017 (backblaze.com)

Posted by msmash on from the pit-against-each-another dept.

BackBlaze is back with its hard drive reliability report. From the blog post: Beginning in April 2013, Backblaze has recorded and saved daily hard drive statistics from the drives in our data centers. Each entry consists of the date, manufacturer, model, serial number, status (operational or failed), and all of the SMART attributes reported by that drive. As of the end of 2017, there are about 88 million entries totaling 23 GB of data. At the end of 2017 we had 93,240 spinning hard drives. Of that number, there were 1,935 boot drives and 91,305 data drives. This post looks at the hard drive statistics of the data drives we monitor. We'll review the stats for Q4 2017, all of 2017, and the lifetime statistics for all of the drives Backblaze has used in our cloud storage data centers since we started keeping track.

    It looks to me like everyone has cleaned up their act. I'm willing to accept a 1% - 2% annualized failure rate for (mostly) consumer drives. It wasn't all that long ago that I thought anything under 5% was doing pretty well. I'm interested to see how the trends for the 8TB+ units play out, but it doesn't look like there are any obvious crap products any longer.

  2. This is the reason I only us HGST by dkone · · Score: 3, Interesting

    I have used nothing but HGST drives for all the machines I have built, including NAS's, for as long as I can remember. This is an awesome study and I am sure it probably has some peeps at seagate steaming right about now.

    A WD Employee I know told me that their manufacturing and development processes for WD and HGST have retained their distinct identities, at least as of 2016. Maybe it's too expensive for WD to switch to the HGST ways of doing things?

    Backblaze is a backup service company. Basically, all they do with their drives is put them up in a bespoke cabinet, slowly fill them up with data at internet speed, then let them running for a long time doing hardly anything at all. Infrequently, when someone loses some data somehere, they read a small portion of them. This is very far from what most people do with their drives. In particular read/write performance and reliability does not matter to Backblaze.
