Do SSD failures follow the bathtub curve? Ask Backblaze

Ah, so Seagate still sucks!

I think you’re reading that chart wrong.

Curcial and WD havea much higher rate on average across all their models.

The 800% is only because they had a single drive for a certain model, and it failed within 2 months. They have a lot of other Seagate models that are much older on average without any failures.

Seems like a shining recommendation to me.

238 SSDs is hardly a good sample size.

That's just what they've added this year. Total drive count is over 3k.

Interesting, from that data it seems SSD reliability so far isn’t too far off from HDDs (at least for Backblaze’s intensive cloud storage workload) despite having no moving parts…

Will be interesting to see how the reliability plays out as they build up their SSD inventory over the coming years

I agree. Consumer use cases of SSDs sees a tremendous benefit if only for accidental damage reasons, but for enterprise data center use I would not have expected the same overall rates of failure.
