separate tablespaces for large tables?

I have question as I have to size (and I would like to do so correctly) tables in a new database coming up for production soon.

Of 96 tables, there are 18 tables to be update frequently, with 7 being tables with 1000's rows, 8 being 100,000s rows and 3 with 1,000,000 rows. So I need to guestimate what pctfree to use in the table DDL.

This is a purchased application so we are guessing on how thw tables will be used.

But my question is should I use 1 tablespace for each of the three large tables? And should I have separate tablespace for each of the 8 midsize tables or use 1? How do you usually work with this?

If these tablespaces are on RAID 5 drives, does this still apply?

I am trying to minimize my subsequent maintenance woes. I will probably use a multiple of the multiblock read count parm in the init file based upon the avg rows size for determining my extent size(subsequent and initial)?

What are thoughts about tablespaces?

Thanks.
