Short answer:  if you make one striping partition -- you have better
overall performance.

if you distribute tables using tablespaces -- you make tables
performance more independant from other tables.  I.e. large
load on one table has less impact on the load on the other
table.

Personally I would keep indexes on one set of drives and data
on other.  All depends on your setup.
