content: So there's something you may or may not know about that data, but there are issues with what can be concluded from it for one reason. The Seagate drives Backblaze was using were refurbished, while the WD and other drive manufacturers were new. Just so ya know. Source: https://www.backblaze.com/blog/what-hard-drive-should-i-buy/  The Seagate Barracuda Green 1.5TB drive, though, has not been doing well. We got them from Seagate as warranty replacements for the older drives, and these new drives are dropping like flies. Their average age shows 0.8 years, but since these are warranty replacements, we believe that they are refurbished drives that were returned by other customers and erased, so they already had some usage when we got them.
