Besides, the IronWolf Pro is also considerably faster than the IronWolf when it comes to maximum sustained transfer rate (250 MB/s vs 210 MB/s). Meanwhile the IronWolf Pro version aimed at enterprise NAS, also has top-and-bottom attached motor, and comes with a five-year warranty. Both models are outfitted with rotational vibration sensors and feature the IronWolf health management technology. Moving on to IronWolf 14 TB and IronWolf Pro 14 TB hard drives for NAS. Seagate rates Skyhawk HDDs for 180 TB/year workloads. As such, these drives are optimized to work for 24/7 and can record data from up to 64 HD cameras. The BarraCuda Pro HDDs are designed for desktops, which is why they are rated for a 300 TB/year workload, but do not feature extensive protection against vibrations (unlike server-grade HDDs), yet they come with Seagate’s Rescue data recovery services.īy contrast, the Skyhawk drives are aimed at surveillance systems that usually employ multiple HDDs, which is why the HDDs feature advance protection again vibration. While it might not seem like something a non-Backblaze user would be interested in, these failure rate statistics are very useful in determining which drives to invest in for home or office use, especially for photographers who regularly have to expand storage in order to accommodate growing image libraries.While the new BarraCuda Pro, SkyHawk, IronWolf Pro, and IronWolf hard drives featuring 14 TB capacity use the same platters, heads and other components, they are still very different products aimed at different applications. The least reliable drive is also from Seagate with the 14 TB ST14000NM0138 having an AFR of 4.66 in Q4 2021 down from 6.29 in Q3 2021. ![]() If you are interested in deep diving into all of the data collected, you can visit all previous Backblaze reports, ranging from 2013, on their statistics page. Since then, particular attention was paid to improving supply strategies. Although such extreme implications, like those experienced due to the global pandemic, couldn’t have been predicted, Backblaze had already gone through a supply chain disruption in 2011 when severe flooding affected Thailand. This particular tactic helped the company to navigate the market needs and limitations during a global pandemic. ![]() ![]() Overall, regardless of the drive capacity or its age, the improvements were visible throughout the entire range of different hard drive models in 2020.īackblaze set a goal at the start of 2020 to diversify the drive models it offered, which came in useful later on when COVID-19 began affecting the world economy and consequently the supply chain. On the other hand, 30,000 larger drives were added to the list - of capacities 14TB, 16TB, and 18TB - and as a group, they too improved to achieve 0.89% AFR. So while Seagate led the way, just about everyone saw marked improvements.īackblaze describes the notable improvement of AFR across the board as “a group effort.” On one hand, older drives as a group - which consists of 4TB, 6TB, 8TB, and 10TB capacity drives - improved in 2020 by going from 1.35% AFR in the year prior to 0.96% AFR. An improvement compared to the year prior, the AFR for all of the models included in the 2020 report was 0.93% which was less than half the AFR for 2019 which stood at 1.89%. As of the end of Q2 2022, Backblaze was monitoring 219,444 hard drives and SSDs in our data centers around the world. “While each drive model has only been installed for about two months, they are off to a great start.”Ĭlose runners up to Seagate were two HGST 4TB drives (models HMS5C4040ALE640 and HMS5C4040BLE640) with 0.27% AFR, followed by the 8TB drive (model HUH728080ALE600) at 0.29% AFR, and the 12TB drive (model HUH721212ALE600) at 0.31% AFR. “The new Toshiba 14TB drive (model: MG07ACA14TA) and the new Toshiba 16TB (model: MG08ACA16TEY) were introduced to our data centers in 2020 and they are putting up zeros, as in zero failures,” the company writes.
