I don't think one can generalize this.  Different applications will have
data with very different
properties.  One may have very dense 5-ary data  which will most efficiently
be stored in a RDB table with 5 columns, but another, maybe using the same
Properties, might be so horrendously sparse that representation as triples
would fact saves memory on your PDA. The sorts of queries you want to do on
the data affect the optimum storage too, of course.

A pint of Sam Adam's Ale to the first person to implement an RDF store which
optimises the underlying database representation as a function of the
statistical properties of the requests made on  it and/or the data stored
