Facts, figures and insights from 250,000 hard drives
For the last eight years Backblaze has collected daily operational data from the hard drives in our data centers. This includes daily SMART statistics from over 250,000 hard drives, and SSDs, totaling nearly two exabytes of storage, and totaling over 200 million data points. We'll use this data to examine the following: - the lifetime failure statistics for all the hard drives we have ever used. - how has temperature effects the failure rate of hard drives. - a comparison the failure rates of helium filled hard drives versus air-filled hard drives.
