![]() ![]() The 6TB from Seagate seems to have very good reliability in my opinion. While these statistics cannot be used to reliably judge the quality of drives from any particular manufacturer they serve as a good reference for general trends in hard drive reliability. 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. The most reliable drive operated by Backblaze remains the 6 TB Seagate ST6000DX000 with an AFR of just 0.11% while having an average age of 80.4 months. The larger capacity newer drives are primarily responsible for this figure with them accounting for 69% of total active drives but only 57% of drive failures. The latest report shows that the AFR for all drives in operation rose to 1.01% in 2021 up from 0.93% in 2020 but significantly below the 1.83% reported in 2019. Backblaze has been purchasing and deploying helium-filled hard drives over the past year and we thought it was time to start looking at their failure rates compared to. The company operates drives of various capacities and ages from Seagate, Toshiba, HGST, and WDC monitoring each models annualized failure rate (AFR). Fast forward a little over 4 years later and 12 TB helium-filled drives are readily available, 14 TB drives can be found, and 16 TB helium-filled drives are arriving soon. This is one of the best blog posts that I have seen in some time and it is VERY informative.Backblaze, a cloud storage provider has recently released their latest annual report on the performance of their 202,759 hard disks in operation. What drive models were failing the most for Seagate? Blackblaze had extremely high failure rates (over 25%) with the Seagate Barracuda Green 1.5TB (ST1500DL003) and Seagate Barracuda 7200 1.5TB (ST31500341AS) drives. The Seagate branded drives start good, but it looks like they fail consistently over the years with a large number of deaths occurring near the 20-month mark. The runner-up is WD with a substantial failure rate in the first six months, but if the drive makes it past that period, it looks like it will live for years. In context: For its latest data on HDD reliability, Backblaze omitted its quarterly stats report and only released the annualized lifetime failure rates of its hard drives. Month by month, how many of the drives are still alive? Blackblaze found that Hitachi do really well, but remember that less than two years ago the HGST brand was bought out by WD. For our evaluation, we removed from consideration 337 drives which were used for either testing purposes or were drive models for which we did not have at least 60 drives. Blackblaze also didn’t show the failures between 5K RPM and 7.2K RPM drives, but they said there was not a strong correlation between RPM and reliability.Īnother chart that we love is the chart below that shows the cumulative survival rate for each brand. At the end of March 2021, Backblaze was monitoring 172,256 hard drives used to store data. ![]() Toshiba 2nd worst, and WDC/HGST (both actually made by. It should be noted that the drives all vary by age in years though and there are various sizes, so this might not be that accurate. Up to this point, it seems, of those brands tested, Seagate had the highest failure rates, on average. At the end of 2018 Backblaze was monitoring 104,954 hard drives used to store data. At the end of March 2021, Backblaze was monitoring 172,256 hard drives used to store data. The chart has clearly shows that the failure rate of Seagate drives is shockingly high, followed by WD and then Hitachi. 2018 Hard Drive Failure Rates: What 100,000+ Hard Drives Tell Us. A failure is when we have to replace a drive in a pod. Everyone always wants to know what hard drive should they buy, so the data Blackblaze released today is a goldmine for tech enthusiasts as it breaks it down by brand and even models.īlackblaze measures drive reliability by looking at the annual failure rate, which is the average number of failures you can expect running one drive for a year. Backblaze has a blog post up today that shows how over 27,000 hard drives from Hitachi, Western Digital (WD) and Seagate have done over the past several years in their Storage Pods. Backblaze is back with an update on its hard disk and SSD failure rates for the third quarter of 2021. ![]()
