I respectfully disagree.  Device property is how error prone it is and its error
correction capability.  Policy is how cautious you want to be with regard to
data integrity vis-a-vis erase block management.  But it *is* a fine line, and
one affects the other.  Plus Ricard makes a good point about devices with other
properties besides ecc strength that could potentially influence the policy
decision.

Thanks,
Mike
