> "statistically speaking, most computers in the world do not use ECC". How can both of these things be true?

... most computers aren't particularly reliable.

I'm curious - are you not monitoring or at least keeping a vague eye on ECC correction events with your existing hardware? If so, are you just not seeing any?

I've never really operated at any sort of "large" scale - a handful of racks at most - but I've always found correction events to be about as routine as IO errors, and certainly way more common than outright disk failures.
