Just in case the RAID5 maintainers aren't aware of it:

In principle, RAID5 should allow construction of a

than any individual drive.
Absolutely not. The more spindles the more chances of a double failure.
Simple statistics will mean that unless you have mirrors the more drives
you add the more chance of two of them (really) failing at once and choking
the whole system.
That said, there very well could be (are?) cases where md needs to do a
better job of handling the world unravelling.
