The primary drives (by size) which are “driving” the increased lifetime annualized failure rate are the 8TB and 10TB drives, which were some of the oldest drives managed by Backblaze. This rise was expected as the age of the fleet continues to increase and is not necessarily a cause for concern given the inescapable reality of the cloud storage business is that drives fail. The biggest change was that the average failure rate (AFR) for Q2 2023 was 2.28%, up from 1.54% in Q1 2023.ĬIO INFLUENCE News: Contrast Security Releases Assess Feature for LLMs to Protect Against AI Security Threats You can see the relative survival rates for Hitachi, Western Digital and Seagate drives in the graphic at the bottom of this post.įor a more detailed look, be sure to read Beach's blog post over on the Backblaze site.In its Tenth Year, the Latest Edition of Flagship Report Focuses on the Upper Limits of the Lifespan of Hard Drivesīackblaze, the industry’s leading specialized cloud storage platform, released the “Backblaze Drive Stats for Q2 2023” report, an exclusive source of data and authoritative resource for storage buyers due to its detail, transparency and historical data.īackblaze’s quarterly analytics report is based on 240,940 hard drives under their management across 31 different models, focusing on the quarterly and lifetime failure rates as of the end of Q2 2023 (April 1 – June 30, 2023). They have been rock solid, and have had a remarkably low failure rate." I've always been a fan of Western Digital drives, so I was happy to see that they also tend to be survivors in the Backblaze world. Of the 1.5 TB Seagate drives, the Barracuda LP is the most reliable, but the Barracuda Green drives are - to quote Beach - "dropping like flies."īeach notes that "if the price were right, we would be buying nothing but Hitachi drives. Seagate drives have a much higher failure rate, although the larger 3 and 4 TB drives tend to be more reliable than the 1.5 TB model. It's not that they're bad drives - they're just not suited for the high-stress environment of a storage farm.Īs you can see in the graphic at the top of this post (taken from the Backblaze study), Hitachi drives tend to have the lowest annual failure rates for Backblaze, followed by Western Digital drives. ![]() These drives tend to spin down when not in use and then spin right back up, which causes a lot of wear and tear and a high failure rate in the Backblaze environment. With the caveat that these are consumer-grade drives being used in a very high-vibration environment under stressful conditions, Backblaze's Brian Beach noted that they've excluded the Western Digital Green 3 TB and Seagate LP (low power) 2 TB drives. Now they're back with a blog post on what company makes the most reliable hard drives. First they told us how long a hard disk drive should last, followed by some info on whether or not those pricey enterprise-grade drives really last longer than cheap consumer-grade drives. Over the past several months they've been providing us with statistics generated by keeping an eye on all of those drives. Online backup firm Backblaze has a lot of consumer-grade hard disk drives spinning away in their open-source Backblaze Storage Pods - 27,134 at the end of 2013, to be exact. ![]()
