In Q3 2023, Backblaze monitored a total of 263,992 hard disk drives (HDDs) and solid-state drives (SSDs) in its data centers. The failure rates for SSDs are discussed in a separate review, but this report focuses on the 259,533 HDDs. The report includes quarterly and lifetime failure rates, as well as observations and insights. One interesting finding is that six different drive models had zero failures in Q3. Additionally, the report discusses the impact of temperature on drive performance and introduces new data fields in the Drive Stats data. The complete dataset is available for download on Backblaze’s website.
