It was Dell actually! https://www.backblaze.com/blog/next-backblaze-storage-pod/ (full disclosure I work for Dell)

They don't state exactly what they're using, only that they're "Dell Servers" which honestly aren't the densest things in the world. I would've thought they'd go for something like the PowerVaults which can fit 84 drives into 5U, which is a little bit denser than their current storage pod configuration (60 drives in 4U).

I did recently do a comparison with our low end servers compared to a JBOD array with the same amount of storage and the uplift for the server configuration was about 10%, give or take. That was limited to a total of 24 drives in 2U however, so not sure how that'd compare to the larger PowerVault arrays or JBODs.

I've been a customer of Backblaze as well for about 6 years now and agree, it's been brilliant for backing up my home network! The reports helped me choose the right drives numerous times over, love their work.
