Backblaze Study Shows Declining Reliability of HDDs, SSDs May Be the Future.

Backblaze, a backup and cloud storage company, has conducted a study of 17,155 failed hard disk drives (HDDs) and found that the average age at which the drives failed was 2 years and 6 months. The study included 72 different models and did not include failed boot drives, drives that had no SMART raw attribute data, or drives with out-of-bounds data. Seagate's 12TB ST12000NM0007 saw 2,023 failures, occurring when each drive was, on average, 1 year and 6 months old. The only model with more failures was the 4TB Seagate ST400DM000.

The Declining Reliability of HDDs: Is it Time to Switch to SSDs?

Backblaze has published its quarterly hard disk drive failure rate statistics, revealing that the annualized failure rates (AFR) have remained relatively stable. As the HDD population grows, the average AFR is 1.54 percent. The latest report shows a recovery in drive reliability after a 10TB failure rate peak, with the newest 16TB drives being the most reliable in Backblaze's HDD buying history. Seagate has the lowest reliability rating, and the average age of failed drives is two years and six months. Backblaze's HDD test data page is available for public use, but users must cite Backblaze as the source and cannot sell the data.
