My opinion is the opposite: I have a separate drive for the OS and the 
hard drives which have the video are one partition only. At the moment 
the OS drive is actually a 13g IDE, while the video drives are 120 and 
250G SATA. I was using about 40Gig on the 120 drive for the OS and 
running out of space....so I swapped in a 40G laptop drive on an adapter 
and took the opportunity to upgrade to Fedora 8 and do a complete 
upgrade. When that was running, I recovered the space on the 120G drive.

I *think* that I have everything set up correctly, and the 2 SATA drives 
spool down when not in use. That left the system with only the laptop 
drive running continuously. (In order to use the 40G drive to transfer a 
bunch of recordings, I later swapped in a 13G 3.5" IDE drive...13G is a 
little small and really leaves me no room for backups. I have to use 
some space on one of the video drives for the mysqlbackup etc...)

So YMMV,, it really could depend on whether you have room in the case 
for the extra drive(s)...And you will not berate yourself for getting 
*large* hard drives for storage....
