I don't have any numbers.
But that's my setup on several servers and I didn't really notice any 
slow down.

There are many howto's out there, but this is the one I liked the most. 
   I followed this one because I was on a remote system the first one I 
setup, but have since used similar steps for many other machines.

And yes...  you simply treat your raid device like any other disk when 
creating a lvm.

Cheers,
Mike
