Use Raid-6, but realize in today's era it is still only good for one failed drive at a time.
Find drives with significantly higher specs for undetected bad sectors (I don't know if drives like that exist or not).
Use a scrubber religiously to make sure there are no undetected bad sectors.
Don't use desktop drives :-) - I don't know if their error rates are actually lower than enterprise 24/7 drives, but their specs apply to an 8 hour duty cycle. Use mirrored RAID6. For any redundant setup, that's probably normal anyway. For home use, it's perhaps not really an option.

I have no idea if the assumptions it is making are still valid.
He's primarily going after the reconstruction time, i.e. the time when an array is running degraded. Earlier when I wrote "the bigger the disk, the bigger the risk", that's exactly what I meant.
