And Robert already noted that they've occurred in his mid-range arrays.  In 
both cases, however, you're talking about decidedly non-consumer hardware, and 
had you looked more carefully at the material to which you were responding you 
would have found that its comments were in the context of experiences with 
consumer hardware (and in particular what *quantitative* level of additional 
protection ZFS's 'special sauce' can be considered to add to its reliability).

Errors introduced by mid-range and high-end arrays don't enter into that 
discussion (though they're interesting for other reasons).
