When do disks fail - backblaze bathtub report

[HDFan]

Backblaze in 2013 reported that disks fail in a "bathtub" fashion. High early failures from infant mortality (0-18 months), decreased failure rates after the infant mortalities (18 months to 3 years), and rising failure rates as disks aged (3-4 years).



With more disks in their arrays, more data, and improving disk quality the infant rate has dropped and the rising rates have been pushed out. Life expectancy was 50% at 6 years, now it is 88%.

Drive Failure Over Time: The Bathtub Curve Is Leaking

Hard drive failure rates tend to follow the “bathtub curve.” What is this curve, and how does it indicate the drive failure rates at Backblaze?

And why is that?

Interesting article!
TBH i would have liked to see a clear differentiation between SSDs and HDDs i.e. 2 different tests.
Fact is they dont behave/wear out the same way.

Yes. So far Backblaze is seeing almost similar failure rates, when adjusted for age. They have just started using more SSD's for boot disks as their prices have dropped. But it will be 3 years or so until they can compare the 6+ year failure rate of SSDs and hard disks.

This parallels my experience. I've had a couple of WD drives fail within 18 months; the rest all worked for years and most were retired before failing.

Where do you back up to?

Interesting stuff. I like back blaze reports, make for interesting reading especially the reliability stuff.

I have a mix of ages and hopefully not all at the same time will they decide to up heads and depart this mortal coil.

Do you own a computer at all?
Or as an explanation for the silence after this post , I assume you're using your grandma's and it just broke ; )
