I haven't seen the REs die due to any direct faults either, ever.

However, they do exhibit issues with fw corruption and the like on 
abrupt power loss, and co.

In my opinion, you do not get redundant REs for it to be immediately 
useful, you keep them for when s* really hits the fan.

Similar analogy to A+B power / network.
