Perhaps this applies to some versions of RAID and some implementations 
of software RAID.   It certainly does not apply to simple RAID (such as 
RAID-1) and fine implementations of software such as FreeBSD's gmirror.

I use gmirror on all my machines at home.

That said, I also have hardware RAID-1.
