Backblaze released statistical data on storage that met the conditions of '100 or more units in operation' or 'total operation days of 10,000 or more days' as of March 31, 2024. The total number of units was 279,297, but 641 units were excluded because they did not meet the above conditions, so the total number of units was 278,565, and the total operation time was 24,478,433 days.



According to the data, the application failure rate (AFR) for the first quarter of 2024 was 1.41%, down from 1.54% in the same period last year and 1.53% in the previous quarter.

According to Backblaze, the overall AFR decreased due to the replacement of 4TB models, which showed a high AFR of 2.33% in the second quarter of 2023.

In particular, in the first quarter of 2024, the following three models achieved zero breakdowns despite not having a large number of units in operation.

- Seagate 16TB model (

ST16000NM002J ): 463 units in operation, total number of days in operation: 42,133
- Seagate 8TB model ( ST8000NM000A ): 226 units in operation, total number of days in operation: 19,684
- Seagate 6TB model ( ST6000DX000 ): 882 units in operation, total number of days in operation: 80,262 days

On the other hand, data for deployments with fewer than 100 units or fewer than 10,000 total days of operation is published separately. Backblaze states that the operating time for these deployments is too short to be reliable in the calculated AFR.



The failure rate trends by manufacturer since the second quarter of 2021 look like this. While Seagate's numbers have dropped significantly, it's interesting to note that WDC's numbers have been gradually increasing.
