We certainly use the block devices -- I just made several dozen today, but 
it appears that it is OS dependent.  On HP-UX, older versions required the
use of the block devices.  Current versions appear to use either.  I didn't
know this, so I have no idea what the possible performance impacts are.  I
will talk to our DBAs.  HP-UX does a number of things oddly, I am not
shocked about this.
