Are these consumer drives being used in an industrial setting?
I'm surprised to see such high AFR from Seagate and WD. These brands have had decades of well-deserved loyalty and trust, and I'd never suspected some of their drives have such high failure rates.
Why are HGST's AFR numbers so much more preferable?
- greggyb 11y ago>Are these consumer drives being used in an industrial setting? Yes, Backblaze is built around consumer hardware and a custom RAID(ish) setup.
- aidenn0 11y agoHitachi has consistently had the best AFR numbers from backblaze for a long time. As far as why other drives have such high AFR, historically Seagate and WD have had much better QA on their server class drives.
- stephengillie 11y agoI wonder if that's due to over-built drives (a quality standard independent of other factors) or if it's related to the specific controllers and other hardware in the Backblaze environment (independent of each manufacturer's drive quality).
- theandrewbailey 11y agoHGST was originally IBM's hard drive division. They probably have inherited much of the reliability secrets that the other manufacturers never bothered with for their consumer class drives (which Backblaze uses). Either that, or they learned a lot of stuff with the "DeathStar" model[0]. https://en.wikipedia.org/wiki/Hitachi_Deskstar#IBM_Deskstar_75GXP_failures https://en.wikipedia.org/wiki/Hitachi_Deskstar#IBM_Deskstar_...
- frik 11y agoYes, but nowadays HGST is no more. The company has been bought by WD, the 2.5" and smaller HDDs are now part of Western Digital. The 3.5" HDDs are now Toshiba due regulatory requirements. http://en.wikipedia.org/wiki/HGST http://en.wikipedia.org/wiki/HGST
- theandrewbailey 11y agoA surprising amount of industry consolidation happened after the Thailand floods a few years ago. There's what, 3 hard drive manufacturers left!? https://en.wikipedia.org/wiki/File:Diagram_of_Hard_Disk_Drive_Manufacturer_Consolidation.svg https://en.wikipedia.org/wiki/File:Diagram_of_Hard_Disk_Driv...
- Shorel 11y agoDamn. I'm still mourning the disappearance of Quantum. Those things were indestructible. But now my cellphone has more storage than these golden drives.
- Someone1234 11y agoThey have a blog post about the whole consumer Vs. enterprise drive thing here: https://www.backblaze.com/blog/enterprise-drive-reliability/ https://www.backblaze.com/blog/enterprise-drive-reliability/ The TL;DR is that the consumer drives had a better ROI since they failed at similar rates and were cheaper.
