How have they got 2k boot drives for 100k data drives? Are these special motherboards with 50 (!) SATA connectors on them? Or is it many machines netbooting and share-mounting root from a handful of control nodes? I get that it's backup, so most of the data is at rest most of the time, but that still seems like a really high ratio of network ports to disk drives.
Either way, interesting that the boot drives are actual drives and not SD card pairs or something, like how vSANs are often set up.
I don’t know why but every time I read one I’m never disappointed. I find the data fascinating. I wish more companies would give information like this but on memory, cpus etc also.
I'm really interested to see how those high capacity Helium-filled drives hold up over time. (i.e. I've been wondering how much leakage is going to be a problem)
Yev here -> that info should be in the SMART stats, so if you see a dip, checking there will give you a lot more context (though we'd likely call that out in our blog).
Does Backblaze have any SMR drives in use, or do you have plans to start using them? Would be really interesting to see if these exhibit a worse failure rate.
Anyway, thanks for sharing this data, I really like the openness.
As someone who runs a tiny archiving operation (about 70 hard drives) I find these stats invaluable and am so grateful to you for publishing them! You make it a lot easier to navigate an expensive and intimidating world of hardware options.

It looks quite detailed--a daily snapshot of all of the SMART values for each individual hard drive.

It's just a shame that their user interface is missing many features I want, otherwise I would use them.
