Let's assume you are asking about Exchange 2007 since you did not say.
However, my answer pretty much applies to any version.
If you are limited to six drives, I would go with:
2 drives in RAID-1, partititioned into two, one for OS + Swap File and the
other for Exchange logs
4 drives in RAID-1 or RAID-5 for the databases
and skip the hot spare, maybe buying an additional cold spare if your
service contract does not provide for fast replacement.
The reason behind two arrays is not so much performance as recoverability,
especially with just 50 users. You want to keep the logs and databases on
separate physical volumes so that if you lose either one, after recovering
you can still get all your data back up to the point of failure.
