So why do we regularly get stories about arrays falling over? Maybe because home users (and bean counters) don't think checking the health of the system is important?

"Enterprise" hardware, and software should not catastrophically fail without warning that comes out of the box, and for sure not fail totally before shipping kicks in.

But a company I know of bought a commercial raid-6 array. Cue a massive panic a couple of years down the line when an operator suddenly noticed two red lights indicating a double drive failure. Nobody'd been checking the raid.
So they had people who were supposed to be looking after it. So it did try to tell them something was wrong. And still they just dodged a catastrophic failure by pure luck rather than judgement.
Cheers,

A sysadmin will do scrubs, will monitor SMART etc, and won't be surprised by a disk failure...
Your assumption that scrubbing and SMART will reliably detect disk failures is not very accurate. There are sudden failures, for starters, where the drive works until it suddenly doesn't: but also SMART is not terribly reliable at the best of times, and scrubbing is more to guard against slow magnetic degradation than to discern whether the drive is on its way out.
