Long time readers: I must start with a mea culpa that this article was not released on our traditional May the Fourth (or thereabouts) report date. Please know I missed making the many and sundry Star Wars puns as much as (I\u2019m sure) you missed hearing them\u2014so, I\u2019ll probably slip a few in, just because. <\/p>\n\n\n\n

That said, there was good reason for the delay. We were diligently investigating a disturbance in the force. (See? We\u2019re back!) We\u2019ll get into the details after we dig into the numbers, but here\u2019s the teaser: this quarter, we observed something unusual in the data that wasn\u2019t entirely a failure trend. It did, however, prompt us to revisit and validate the assumptions behind our Drive Stats analysis before publishing.\u00a0<\/p>\n\n\n\n

Q1 2026 Hard drive failure rates<\/h2>\n\n\n\n

As of the end of Q1 2026, Backblaze was monitoring 345,662 drives used to store data. For our evaluation, we removed from consideration 3,907 boot drives and 492 hard drives, as they did not meet the criteria to be included. We\u2019ll discuss the criteria we used in the next section of this report. Removing these drives leaves us with 341,263 hard drives to analyze. The table below shows the annualized failure rates for Q1 2026 for this collection of drives.<\/p>\n\n\n\n
