Unless you have a specific reason to do it, you will gain no advantage in
partitioning your drive. Partitioning was useful in days gone by when growing
drives sizes would outstrip the capabilities of the different operating
systems, but those days are long gone. Mac OS X is capable of address volume
sizes of many terabytes. You may well have legitimate reasons for wanting to
partition your drive, but optimising drive space would not among them. All you
would be doing is increasing the complexity of your disk management regimes
(back up, etc). Your space concerns are already being dealt with by the fact
that you have a RAIDed drive. This means that your My Book World Edition
actually contains two hard drives, one being an exact copy ("mirror") of the
other. Ay time data is written to one drive, it is also being written to the
other in exactly the same way. This allows you a safety valve in that if one of
the drives fails, it can simply be replaced with a new one, without the loss of
any data.
If you really do want to use partitions in the interest of security or
increased data organisation, you should consider the use of Disk Image files,
created using Disk Utility. These have many advantages, not the least of which
is that fact that they can be password protected, and they effectively achieve
many of the same aims as partitioning.
