Not exactly; I was wondering if there is a breaking point, as in
"adding more drives only increases the chances of the whole array to
fail" beyond that point, and "adding more drives reduces the chances of
the whole array failing" before that point.
Wouldn't it be useful if that breaking point was known for all kinds of
raid setups? The calculation would have to consider the chances of
several drives failing at (about) the same time.
