    Seagate faces class-action lawsuit over 3TB hard drive failure rates

    kingfish

      ""Seagate failure rates on the ST3000DM001 weren’t just far higher than other drives, they were also distributed differently. Normally, products follow what’s called a “bathtub curve” failure rate. That means an initial high period of failure as defective units die, followed by low overall failure rates until end-of-life, when hardware begins burning out. The Seagate drives in Backblaze’s storage pods did not exhibit this type of curve.""

      As of April 2015, just 6% of the original 3TB drives Backblaze purchased were still in service. This kind of data could be evidence of a significant problem with the drive family.

       

      The complaint notes that Seagate’s ST3000DM001 was the first 3TB drive to use three platters at 1TB each. This is in contrast to other 3TB drives then on the market, which used 4-5 platters to hit their 3TB densities.
