    If you are thinking of buying a high capacity HDD it might be worth a look at this data.

    Seems a little unfair to be comparing consumer drives against enterprise grade drives

    Pretty much, do not touch Seagate and WDC with a 10 foot pole!

    Yes, it should be compared against Samsumg and Toshiba. I believe both are more reliable than Seagate or WDC and cost less.

    After experiencing 3 Seagate failures in short succession some time ago, they are off my list of considerations. My WD drives have all been impeccable and will probably die because of age one day.

    I also had problems with Seagate, not only did the drive fail, they tried to say they didn't recieve the drive and I should chase the courier (they had initially confirmed that it was received 3 times prior)

    Terrible company to deal with

    I assemble audio and video workstations here and there, and service them. Last couple of years I experienced increased failures from both Seagate and WD hard disks. Decided to go with Toshiba and HGST instead. No problems so far. One has to be in the loop regarding these things, because everybody can become next Seagate.

    Re: Backblaze publishes hard drive reliability stats for Q2 2016

    So, do not touch WDC because Toshiba is more reliable... despite Tosh having an average annualised failure percentage of 8.79%, compared to Seagate's 6.65% and WDC's 5%...?

    HGST, on the other hand, looks to be doing alright for themselves...

    Re: Backblaze publishes hard drive reliability stats for Q2 2016

    Just a few days ago one of my Seagate 2TB Barracuda (ST2000DM001) powered itself down, and now on cold boot it's only able to click a few times before giving up - it hasn't seen very much service during its <3 year lifespan, and yet it's well out of warranty.

    In contrast I have a load of 160GB Barracuda IDE drives still going strong, but I'm not buying any more Seagate drives. I've had better luck over the years with WD and Samsung, and it seems post-75GXP (yes, I had one which inevitably failed) IBM/HGST has long fixed their problems.

    Re: Backblaze publishes hard drive reliability stats for Q2 2016

    I just buy drives with as long a warranty as I think I'm going to need them for then treat them as if they're all going to fail one day so RAID arrays, ceph, whatever to protect my data. Latest batch of 2TB drives are toshibas with warranties expiring mid 2017. By then 4TB should be the new best price point so the 2TBs can fail for all I care.

    Re: Backblaze publishes hard drive reliability stats for Q2 2016

    Just wanted to point out that HGST has been part of WD for some years now, while Samsung drives likewise have been a part of Seagate for some years as well.

    Actually, there are only three manufacturers of HDDs left and that's WD, Seagate and Toshiba.

    HGST and WD operate as separate entities though which compete - it seems as if their drives really are engineered differently despite the overall ownership.

    Quite! Which does make me smile when some says that they'll "never buy anything from X" and then go on to wax lyrical about a different brand from the same company.

    Personally I'm cynical enough to believe that most of these drives are equally bad, and it's just pot luck whether you get a good one or not. For example I've got a Seagate SSHD that's been really good, while I've had issues with WD Black (slow) and Blue (failed) drives. Quite irrationally impressed with WD Red drives though.

    Career status: still enjoying my new career in DevOps, but it's keeping me busy...

    They may be owned by the same parent company, but as others point out, that doesn't mean they have common manufacturing processes, or that the different brand names are just relabelled versions of the same product.

    Indeed - a change of ownership doesn't immediately and inevitably (or even in the short/medium term) lead to a change of factory, processes, design or quality levels, and it is interesting to observe in the data that is available from the likes of Backblaze the effects (or otherwise) of a change of ownership.
