Hey there Experts,

I'm getting ready to build an Ubuntu Desktop box that I'll be using for a virtual machine server using Ubuntu desktop and virtualbox.  I would like to create a RAID array to allow for hard drive fault tolerance but I'm a little shaky on the details of this, especially in Ubuntu.  

I have 3 500GB SATA drives that I would like to use for the array.  I also have a 250GB SATA drive which came with my server.  I think I would like RAID5.

I guess the most basic question is this:
Should I add the 250GB drive, install Ubuntu on it, and then create my array from the three 500GB drives to hold my VMs?  or

Should I just leave the 250GB drive out of the picture and install Ubuntu and my array on the three 500GB drives.  

It seems counter-intuitive to me to use the 250GB for the OS but I have seen this setup referenced on the web.  

Anyway, any help you can give will be greatly appreciated.  

Thanks!

PS - there is no hardware RAID controller and the budget is shoestring so we'll be sticking w/ software RAID.
