It's disingenuous of you to keep putting the error probabilities in terms like "nearly 1 in 10" without acknowledging the context that you're talking about the probability of a transient error occurring at any time over the course of a full year of continuous operation. Most people actually are comfortable with the idea that their equipment will have occasional downtime or faults, but you're trying to paint a very different picture.

Buddy, I would heartily encourage you to believe whatever you makes you happy. Your insult is false and petty, and I think you're pretty wrong about the rest of that.

I personally consider it pretty disingenuous to call a fault that damages data on disk 'transient'. The root cause may have been transient, but the damage doesn't go away if/when a stuck bit functions normally again. Or do you consider a stroke leading to paralysis a transient injury?

I'd also like to see a cite that "most people actually are comfortable with the idea that..." a 'transient' fault that scrambles random data they've chosen to keep. Where, exactly, are you getting this?

Finally, assuming you have some actual basis for that claim, how many of those people run ZFS? You wouldn't conflate nontechnical people who buy the cheapest box at Best Buy with folks who take the time to configure software RAID across several disks using a nonstandard filesystem, would you?
