Thanks for the insights!

Is the bad sector read rate abnormally high? Are GCE's SSDs particularly error prone? Or is the failure rate typical, but a bad sector read is just incredibly expensive?

I assume you investigated using various RAID levels to make an LRU cache acceptably reliable?

It's also surprising to me that GCE doesn't provide a suitable out of the box storage solution. I thought a major benefit of the cloud is supposed to be not having to worry about things like device failures. I wonder what technical constraints are going on behind the scenes at GCE.

Yes, incredibly error prone. Bad sector reads were observed at an alarming rate over a short period - well beyond what is expected if you were to just buy an enterprise nvme and slap it into a server.

That's quite an indictment of GCP if their Local SSD's reliability is that bad.
