Exactly.
And as for the "strain" when one member dies, how is this "strain" different
than the daily thrashing of rsync?

I have software raid 1, and raid 5 arrays where a disk has failed and the
rebuild happened without any un-availability, and happened in the background
such that the users were never even aware it was happening.

I use Rsync between machines (some offsite) and raid 1 within a machine.
I'm a belt and suspenders sort of guy.

Raid, especially Raid 1 is as easy as falling off a log these days.
