What do you mean with "usage pattern"? Usually (in 99 % of the cases) this
is not necessary since the I/O is spread always across all volumes. A
(parallel) access to read from N volumes is much faster than a single read
on a single disk. 

How often do you need to move tables from one tablespace to another - in
real life?
