Backblaze HDD drive statistics 2024/Q1

[EAZ1964]

With the usual warnings that datacenter use differs from typical NAS use, and that conclusions from statistics need careful interpretation:

Backblaze Drive Stats for Q1 2024

Read the Q1 2024 Drive Stats report, including the latest annualized failure rates (AFRs) and a check in on the average age of drives.

There is not much news, some of my observations:

• this blog edition pays a bit more attention to age of the failed drives
• some 14TB HDD types are much less reliable than the 16TB

Enjoy the read

Seagate 16TB... 0% failure.... makes me happy about my last drive purchases....

Take care with your interpretation, possibly your 16TB disk is from group 2:

“Regardless, the lack of observations (drive days) over the observation period is too low to have any certainty about the calculated AFR.”

Backblaze normally leaves out group 2 disks from the Blog, as confidence level is too wide.

This is exactly why I warn for careful interpretation
