How about for database? In particular postgresql.
How bad would RAID 5 be for it?

I still have some, limited, hopes I can convince the owner of the company 
to go with RAID 10 with 10K rpm drives.. the most likelyhood we will go 
with RAID 5, 7200rpm drives for a database project ahead. Alternatively I 
will see how RAID 5 with 10K rpm SCSI drives compares price wise, but I am 
sure it will be substantially more. :-(
