More than half the stored data in the world resides on hard drives. Yes, a 50+ year old technology is storing our photos, music, research, taxes, and more— and nobody blinks an eye. Given that over one zettabyte of hard drive storage shipped in 2020, this storage media is not going away anytime soon.

We at Backblaze manage over 200,000 hard drives to store over 1.3 Exabytes of data. Since 2013 we have tracked every hard drive we've used and each day we record their SMART stats, giving us a unique trove of data that we have regularly analyzed over nearly a decade to learn about hard drives from the inside out. We know how often they fail by model, manufacturer, and size. We can answer the question, do hard drives failure rates follow the bathtub curve? We know how temperature affects hard drives. We can show you how machine learning capabilities could be used to predict hard drive failure. We can even provide a life expectancy forecast for all our hard drives. One more thing, we've open-sourced the data so you can do all of this yourself, just for fun.
