![]() The computation is done based on a basic math equation that starts off with (drive failures divided by drive days divided by 366) multiplied by 100. This specific cloud backup service consistently posts different detailed stats on certain failure rates, which also includes the popularly estimated "annualized failure rate." Backblaze backup cloud storageīackblaze actually runs storage pods that already host more than 129,000 HDDs from a wide range of manufacturers including a wide range all the way from 4TB up to 16TH. The huge question is "are Seagate HDDs really unreliable?" this is where Backblaze starts to come in. There is apparently another consideration which is Seagate.Īlthough Seagate HDDs still leads on when it comes to complaints compared to any other manufacturer. The article noted that a possible alternative would be to transition into multiple smaller packed HDDs but then this takes the convenience that the HDD offers in the first place. The downside mentioned is that if your HDD breaks, you could potentially lose all of your data inside as well. The article states that the bigger the capacity of the HDD, the more space will be available for things that you do not want to clutter up your SSD. HDD's importanceĪn article by PC Gamer stated that their primary interest was in larger capacity HDDs due to the inherent conundrum. In a different report, Backblaze actually offered up some of their primary data on a number of 16TB HDDs in its own employ. Bulk HDDs still have their place, however, that might change as demand for memory soars with games start getting beefier and beefier. They also note that the enterprise drives come with 5 year warranties, and features such as higher performance sequential writes and power management features that datacenters can use.With the SSD making its way into everyone's computer and the technology getting heavier and heavier, the traditional mechanical hard disk drives lose fashion as the primary source for memory. That's a 0.89 percent AFR for the last three months.Ĭommercial vs Enterprise drive reliability finds that Seagate's consumer 8TB drives had a 0.1 percent AFR advantage over the enterprise 8TB drives. Nearly 80 percent of all the Backblaze drives are less than three years old.īB is retiring their oldest drive, super-reliable HGST 3's, which is actually raising their cumulative failure rate, because the larger, newer drives are slightly less reliable.Įven the new - whose manufacturing processes are still being tweaked - 8TB drives are proving quite reliable, with only 46 failures among 24,328 drives. Takeawaysĭisk drives are mechanical devices with bearings and lubricants that wear out, so age is a factor. Congrats to the manufacturing and engineering teams that made that possible. It's too early to draw hard conclusions, but 1,220 Seagate 10TB drives were put into service without a single failure. The best news is that the latest 10, and even a few 12TB drives, are all performing flawlessly. Disk drives really are getting more reliable. In fact, the Backblaze drive failure rate - 1.84 percent - is their lowest quarterly failure rate ever. Hard drive sales may be slowing, but hard drive reliability is rising - as measured by annual failure rate ( AFR) - even for the newest 8TB drives. ![]() They have over 86,000 drives installed in their own Storage Pods. Backblaze Storage Pod 6.0 with 60 hard drivesīackblaze released their Q3 2017 drive reliability findings this morning, and the news is good. ![]()
