Drive configuration pros and cons

I am about to reconfigure my PE2550 with some larger hard drives. I was going to put in 3 X 73Gb drives and configure them as one RAID 5 container giving me 146GB then create 2 volumes, one for the OS and the other for my application data. Then I had an idea to use one of the smaller drives I was taking out as one container for the OS and use the 3 new drives as another container for my applications.
 
Besides having no redundancy for my OS can anyone think of any other pros and cons from this config. I want to make sure I'm covering all bases before I proceed.
 
Thanks!

well. i guess it really depends on the uptime you require. by making a logical drive and using that for both OS and data, you would have the best available uptime. If you'd rather have the extra space and can sacrifice the downtime if the OS hoses itself, go with the extra drive.

But i guess thats an obvious thing. Less obvious consideration : depends if heavy use of the OS disk is required. By raid-5'ing the OS, you can get a little faster read/write than with a single disk alone (assuming you have a good SCSI card).

ferb!
