I would suggest the three RAID 1 configuration. Keeping the logs, database
and OS on different volumes is the key to best performance.

preferable performance-wise than my colleagues suggestion; seperate RAID 1
for the OS and pagefile, another RAID 1 for the logs and a third RAID 1 set
for the NTDS.DIT and SYSVOL. This isn't a 'winning' exercise but we need to
be sure to consider all aspects of both approaches. Can anyone here point us
to some documented analysis of these configs, or offer their own opinions
please?
