Copy and pasted from my response in a different comment: > BackBlaze was typically only using consumer drives Disclaimer: I work at Backblaze. If anybody is curious, in our blog posts we list the exact serial numbers of all of the drives. See here for an example: https://www.backblaze.com/blog/wp-content/uploads/2017/05/blog-hd-stats-q1-2017-table.jpg https://www.backblaze.com/blog/wp-content/uploads/2017/05/bl... We have been at this for a while, and the distinction between "consumer drive" and "enterprise drive" is not what most people think it is. But in the end it simply doesn't matter -> the differences between failure rates of individual MODELS of drives in one line is larger than any difference in failure rates of "consumer" vs "enterprise". TL;DR - Backblaze uses both "consumer" and "enterprise" drives. But check the individual drive serial number, that is more important than arbitrary marketing groupings.
