Have you tried a new disk array? Is the database crashing when a volumne runs out of space? You can also try to look at your data and see if it is being stored efficiently. DBMS_SPACE is a good place to look.

I do need the space its taking up as the disk is now almost full (56k free) and Oracle is running extremely slowly.
