So then how do you correct soft errors? You seem to have a soft fetish...I want to protect both, you don't seem to feel the need to protect the hardware side. Hence why you keep talking about mtbf.
Are not we better off trying to do our best protecting all types of errors? If I hire a IT manager I don't want just him relying on what he's seen, but what is true. I had a manager at a grocery store I used to work at order ad based on what he liked and not what the buying habits were for the area. That seems to be the way you work out data protection schemes. All your problems are soft related, I've seen more hardware related. I would choose to try and protect both, you ignore one.
