This data aligns closely with a similar analysis conducted by Secure Data Recovery, which found an average HDD lifespan of approximately 2 years and 10 months before failure. In 2021, Backblaze added 40,460 hard drives and as of December 31, 2021, we had 206,928 drives under management. The overall average failure rate for Q1 2023 was 1.54%, a rise from 1.21% in Q4 2022 and 1.22% in Q1 2022.
In contrast, WDC claimed the lowest average failure rate at 0.31%. Seagate emerged as the leading brand in drive failures, with its 12TB ST12000NM0007 model experiencing 2,023 failures, an AFR of 7.46%, and an average lifespan of just 18 months. The data was compiled from 30 different HDD models, ranging from 4TB to 12TB, with a focus on Annualized Failure Rates (AFR) for products manufactured by HGST (7 models), Seagate (13 models), Toshiba (7 models), and WDC (3 models). Hard Drive Reliability: A Look at HDD and SDD Failure Rates.
We have both HGST and Seagate helium-filled hard drives, but only the HGST drives currently report the SMART 22 attribute. Oct 2021 Latest activity Latest activity: 8. For our evaluation, we removed from consideration 337 drives which were used for either testing purposes or were drive models for which we did not have at least 60 drives. Backblaze statistics 2Q/2021 Thread starter jeyare Start date 5. Updated Seagates spinners stopping spinning more often, though. At the end of March 2021, Backblaze was monitoring 172,256 hard drives used to store data. Backup bods Backblaze: Disk drive reliability improving. The ones used as boot drives in its datacenters seem to be, but perhaps not over time. The report assesses the reliability and failure rates of various models, and since its inception, the company has witnessed 17,155 HDD failures.īackblaze, the cloud storage and storage analytics expert, has published a comprehensive report detailing the reliability of hundreds of thousands of hard drives employed in the company's servers. On average, the failed hard drives had an operational lifespan of merely two years and six months, which is less than the minimum three-year warranty mandated by European law. Backblaze thinks SSDs are more reliable than hard drives. As of Q1 2023, Backblaze managed 236,893 HDDs.
