What is the optimal RAID1+RAID5 configuration and why?

My thinking is:

RAID 1 SAS 15k 146GB drives for the OS. RAID 5 SATA 7.2k 300GB drives for the data.

My opinion is that the OS partition should be as fast as possible, and that the data partition should have a compromise between high storage space and low cost as there will be several HDDs to purchase initially and possibly more if I need to expand the volume.

EDIT-- This is going to be an SBS server for a small business so blistering data throughput isn't as important as cost and efficient utilisation of the HDDs.

It will be running SBS 2011 with at least 15 concurrently connected AD users (SBS allows up to 75 connected users).

There will be a single exchange mailbox store with a 2GB mailbox per user. MSSQL 2008 will be running with at least 1 medium sized database (20 GB).

Sharepoint will be accessed concurrently by at least 5 users. There will also be file storage requirements: one home folder per AD user and I would estimate that each user would store at least 1GB of data in their home folder.

Also a couple of network shares accessed by no more than 2 users at a time.

Finally the server will be used for DHCP, DNS and WSUS.

EDIT-- Oracle is irrelevant. It will be storing files, and some databases under MSSQL.

I've been backing up my SVN repo and trac environment using a weekly cron job and 2 custom scripts. This has been going to Joyent Strongspace; but since they have discontinued the service, I need an alternative provider. I would prefer amazon S3 because I already use it, but any alternative that will work without too much (any) changes to my process will be welcome.

Here are my 2 scripts:

#!/bin/sh
rsync -rltpvz --delete /svn/ kryptonite\@[email protected]:svn

#!/bin/sh
rsync -rltpvz --delete /var/lib/trac/ kryptonite\@[email protected]:trac
backup linux rsync amazon-s3 joyent
