So you're telling me that if I have two disks in a RAID 1 pair, and then
I add two more disks in a RAID 1 pair, the chances of both disks in the
first pair dying at the same time go down? I don't buy that. They're
completely independent of the second pair. Because they're independent,
you actually add them together (kind of), and you increase your chances
of a pair failing.
They're still pretty slim, though. I agree that RAID 10 is more
reliable than RAID 5.
