Firstly, they predicted that the number of 4TB would decrease by more than half, from 35,000 to 15,000 in reality, adding drives took priority, and by Q1 2020 there were only marginally fewer 4TB drives. Drive days represents the number of days that all of the drives being observed were operational, and 366 is used because 2020 is a leap year.īackblaze made several predictions based on the stats in Q1 2019. Backblaze calculates the AFR using the equation drive failures/ (drives days/366) * 100. In Q1 of 2020, four hard drive models from three manufacturers had no failures. This marks a significant improvement on Q1 in 2019, which saw an AFR of 1.56%. The report notes that the Annualised Failure Rate (AFR) for Q1 was 1.07%, the lowest for any quarter since Backblaze started keeping track in 2013. With so many drives deployed across their four data centres, Backblaze has a unique insight on hard drive durability. These hard drives are sourced from a range of manufacturers, and vary in capacity from 4TB to 16TB. Spread across four data centres, Backblaze’s cloud storage ecosystem has 132,339 spinning hard drives. But how much of a problem is this with modern hard drives?īlackblaze’s recent report detailing hard drive stats for the first quarter of 2020 is incredibly interesting, as it shows that modern hard drives are actually quite resilient. One of the main drawbacks of hard disk drives in their limited lifespan, particularly if they see a lot of use. But magnetic platters are also capable of holding cast amounts of data, and this is one of the reasons why the hard drive hasn’t been completely replaced by the solid-state drive (SSD) just yet. Hard disk drives (HDDs) are mechanical, and while they’re much more susceptible to physical damage, the data recovery process is much simpler. Could we be seeing a slow but delayed demise? But a recent report from Backblaze has thrown some doubt at this. Many have long-predicted the end of the hard disk drive.
