raid 5 partition table example

[Matt Fair]

Hello,
If you use raid 5 would you want to also have separate partitions for
/home, /usr, etc. ?
If so, what would be the best way to partition them?
If you have done this, could you show me your partition table?  I have
only been able to find a partition table for raid 2.
I have 3 10 Gig hard drives I would like to put into a raid array.
Thanks
Matt
