On: ZFS copies=n is not a substitute for device redund...

[yarg]

A minor quibble: your unit of time should be nanoseconds.

[nitrogen → yarg]

That, or maybe clock ticks

[garmaine → nitrogen]

That's what I meant. Speed of light is 300,000,000 m/s. Divide by 3Ghz (3,000,000,000 clock/s) and you get 10 cm/clock. Wave propagation in an actual conductor is slower still.

Edit window has elapsed though.

[Piskvorrr → garmaine]

So, essentially, the physical die size and c impose a hard constraint on tick propagation? Whoa!

[garmaine → Piskvorrr]

Yup. Only way to go faster (single-core speed) is to shrink smaller, and reduce coordination between cores.
