No mention of disk failure rates? curious how it's holding up after a few months

darkr Nov 20, 2020 View on HN

This is a pretty common pattern with disk failures - in my experience they either tend to fail in the first few months, or they make it for the duration.

Do they use HDDs? If so, does that mean the older HDDs had less failures?

aquadrop Jun 2, 2014 View on HN

In your experience, when you had those 12 failures, did drives die suddenly or was it "expectable" because of high usage (high wear)?

My experience is 10 drives from 2009-2012 that still work and 10 drives from 2014 that have failed.

What's your experience with the Atwood Failure Rate for SSDs?

theragra Feb 19, 2025 View on HN

I haven't had ssd failure at all. But at least three HDDs failed, maybe four.

Did you keep any data on how often you got to replace your drives because of such signs ?

kayoone May 2, 2011 View on HN

I have 3 different SSDs since early 2009 (64 & 128GB Supertalent Ultradrive ME + Intel X25-M 80GB) and the latter two are in heavy use everyday. They all work fine until today, but this article worries me a bit ;)

Do larger capacity drives have higher failure rates?
