It's worth noting that the vibration caused by multiple discs running in tandem 24/7/365 is known to be the biggest bugbear for drive failures.

As a result, WD, Seagate and Hitachi have now all introduced drives suitable for use in NAS devices with more than 8-bays... [and you can bet that it is these larger devices that Backblaze is using for their 34,881 drives and over 100 petabytes of data].

The different environments and use cases between Backblaze and a typical user's home is worth noting when making a buying choice based on this data.
