    The most reliable hard drives in 2015, according to Backblaze


    Backblaze, a cloud storage company, records the reliability of different hard drives from different suppliers. The 2015 numbers reveal the success of the 4TB Seagate ST4000DM000, of which Backblaze now owns almost 30,000.

    Here's a surprise: Seagate hard drives may now be more reliable than Western Digital models, according to Backblaze's Hard Drive Reliability Review for 2015. The failure rates in the bar chart above are cumulative from April 2013 to the end of 2015, by which time the company had 56,224 hard drives containing customer data in 1,249 Backblaze Storage Pods.

    Previously, some Seagate hard drives exhibited high failure rates, with almost a third of Backblaze's 3TB Seagate drives (ST3000DM001) failing in 2012. In September 2014, I reported that "the three least reliable drives tested are all Seagate Barracuda models. The Seagate Barracuda 7200.11 has had an annual failure rate of 24.9 percent, the 3TB 7200.14 of 15.7 percent, and the 1.5TB Barracuda LP of 9.6 percent." (See Who makes the most reliable hard disk drives? Backblaze has updated its stats)

    As Robin Harris reported here in April, Backblaze eventually pulled the 3TB Seagate drives out of service.

    Historically, HGST (formerly Hitachi Global Storage Technologies, but now owned by Western Digital) hard drives have been by far the most reliable, but in 2015, Backblaze still went for Seagate. The company explains that "the HGST 4TB drives, while showing exceptionally low failure rates, are no longer available having been replaced with higher priced, higher performing models. The readily available and highly competitive price of the Seagate 4TB drives, along with their solid performance and respectable failure rates, have made them our drive of choice."

    Backblaze now reports that the Seagate 4TB hard drives had a failure rate of just under 3 percent, which was only a little higher than the 4TB WD models (barchart below).

    I wonder which WD drives were failing, as the 4TB ones had the 2nd lowest failure rate according to the 2nd graph.

    WD has proven to me to be very reliable. Other than my new Samsung SSD I just purchased for my boot drive(which was a awesome deal) I will always buy WD either USB or internal drives.

    SSD is proven reliable and alternative storage
    but different usage scenario
    for archiving mass data, traditional hdd have more benefit over SSD
    beside the capacity, data retention on SSD is limited (client at 30C 1year/enterprise 40C 3months without power)
    although it possible real scenario better than that, i believe no one willing to take risk losing data
    thus for those usage, people still using traditional hdd

    I would say it's their green ones, I have a storage array I put together that has 8 of them of in it and 3 failed within the past 2 years.

    Lol they do all of their drives in colors. The green ones are the environment friendly ones. Actually this is new...I'm almost positive its the green ones now:

    We are making changes to simplify the hard drive selection process for our customers by consolidating our mainstream PC product offerings to only the WD Blue family. All current WD Green capacity, cache and form-factor configurations will remain available through their lifecycle, but under the WD Blue brand*. Although WD Green hard drives are part of a new family, they're still the same reliable hard drive you've grown to know and love over the years.

    *The WD Green hard drive functionality will remain the same. However, it will now have a WD Blue label with a slight change to their model numbers (ex. WD60EZRX will now become WD60EZRZ).
    I also found their new disclaimer:

    Disclaimer


    • WD is making it easier for its customers to choose the correct drive for their desktop and laptop. Over the next several months, WD Green 2.5-inch hard drives (with up to 2TB capacity) will be merging with WD Blue 2.5-inch hard drives (with up to 1 TB capacity) to be collectively sold under the WD Blue brand. Product availability is dependent upon each retailer. Please visit the WD Blue 2.5-inch hard drive specifications page for more information on the expanded lineup.

    This makes me laugh as I remember days when hard disks often failed. Even relatively poor one by modern standards are far more reliable than some years ago.

    Any 'old boy' knows to make image backups regularly to protect against hdd failure!
