SBS2003 Partitioning

I have been reading through this group's discussions around best practice
for partitioning a Small Business Server.

When setting up an entry-level system using for example an HP ML110 with
80Gb disk I have always used a 15Gb partinion for the OS and a second
partition using the rest of the disk to store the SQL database, Exchange
store and logs and users shared folders and other file shares. I have read
recently that it _could_ be a good idea to put the pagefile on a different
partition but it seems to me that this would degrade rather than enhance
performance.

I was interested to find this on the HP website
http://www27.compaq.com/SB/ExchangeSizer/ExchangeASP/PreConfigSolutions.aspx?PreConfigSolId=0

Is this a good idea ?
I would be interested in hearing the views of the experts. I don't want to
start discussions about adding extra spindles and RAID types for OS and
Data/SQL/Exchange I just want to find out in an entry-level system with a
hardware RAID1 configuration whether two (or even one) partitions are
acceptable or whether the configuration recommended by HP gives any
advantages.

Is it a good idea to keep Exchange/ SQL on seperate partitions in order to
be able to de-frag the other partitions? Should defrag be necessary anyway
and if so at what intervals?
