Backblaze's SSD vs. HDD Reliability Showdown: The Verdict is...

Backblaze conducted a long-term reliability study comparing SSDs and HDDs in their data centers. Initial data suggested significantly lower failure rates for SSDs, but this was skewed by the much shorter operational lifespan of SSDs and varying drive-day counts. Retrospectively analyzing HDD data to match SSD age and usage revealed comparable failure rates between the two. Long-term data shows HDD failure rates increase dramatically with age, while the future trend for SSDs remains unclear. Currently, using failure rate as the sole deciding factor when choosing between SSDs and HDDs is questionable; cost, speed, and other factors should weigh heavier in your decision.
