StorageNewsletter.com, Monday, November 18th, 2024
As of the end of 3Q24, Backblaze was monitoring 292,647 HDDs and SSDs in its cloud storage servers located in our data centers around the world.
It removed from this analysis 4,100 boot drives, consisting of 3,344 SSDs and 756 HDDs. This leaves us with 288,547 hard drives under management to review for this report.
We'll review the AFRs for 3Q24 and the lifetime AFRs of the qualifying drive models. Along the way, we'll share our observations and insights on the data presented.
Hard drive failure rates for 3Q24
For our 3Q24 quarterly analysis, we remove the following from consideration: drive models which did not have at least 100 drives in service at the end of the quarter, drive models which did not accumulate 10,000 or more drive days during the quarter, and individual drives which exceeded their manufacturer's temperature spec during their lifetime. The removed pool totalled 471 drives, leaving us with 288,076 drives grouped into 29 drive models for our 3Q24 analysis.
