Love and appreciate that Backblaze presents this data, but there are some obvious issues: comparing the annual failure rate of a pool where avg. age is 1 year to a pool where avg. age is 3 years isn't a great comparison.

Rather than annual rates, I'd really prefer to see failure rate after six months, one year, two years, etc. This would make it easier to answer questions like "was drive X always bad? Or just when new? Or just when old?"



Backblaze employee here - we're going to release the raw data in a couple weeks, so everybody can do their own analysis.


Can't wait for this, but it'd be great if you considered having "real-time"-ish data feed for everyone to hook into. Then we don't have to wait for the annual blog post ;-)
