Keep in mind that RAID 5 also costs tens of thousands of dollars to 
recover if something does go wrong. I've seen a surprisingly high 
number of failures of RAID 5 arrays, considering how few of my 
clients could afford them in the first place. I'm starting to think 
it's safer & cheaper (at least in the long run) to stripe a couple of 
RAID 1 arrays than to do a RAID 5. I'm definitely convinced that RAID 
1 is the way to go if your needs can be met by the capacity of a 
single disk.

Absolutely agreed. (Just make sure it's good hardware!)
