![]() ![]() Notably, the 10TB drives had the highest AFR (3.73%) for 2022. Hard drives with a capacity of 10TB or lower showed an overall 0.85% increase in failures from 2021 to 2022. Do note that the drive count and drive days for the two models are significantly lower than other models, so again the numbers can skew wildly from a few bad apples. Like any other hardware, hard drives are more prone to failure as they age.Īt first sight, the HGST Ultrastar He8 8TB (HUH728080ALE604) and Seagate Exos X14 14TB (ST14000NM0138) have the highest failure rates at 5.27% and 5.70%, respectively. The main reason for the increase is due to the age of the drives. For example, Backblaze recorded an AFR of 0.93% in 2020 and 1.10% in 2021. The annualized failure rate (AFR) for hard drives has increased over the last three years. Furthermore, the Seagate 8TB drives had only been in service for 22,839 days and are primarily used as spare drives to replace 8TB drives that have died. Backblaze stated that it only had 79 drives on active duty, so the sample size is tiny compared to some of the other models that total up to tens of thousands. According to the numbers, the hard drive presented zero failures in 2022. Seagate's Exos 8TB (ST8000NM000A) was the report's star. That leaves Backblaze with 230,921 hard drives for analysis. The company removed 388 drives from the report due to them being test drives or models where the sample size is less than 60 drives. Of the entire lot, 4,299 are boot drives, and the remaining 231,309 are data drives. According to the company, it has 235,608 hard drives as of December 2022. Given the nature of the company's business, the statistics indicate which hard drives are the most reliable.īackblaze has some insight into which hard drives make the most durable storage devices. However, hard drives continue to remain relevant when it comes to secondary storage. Nowadays, many consumers are already likely using one of the best SSDs on the market. Cloud storage and data backup company Backblaze has published its annual report of hard drive failures for 2022. ![]()
