We are building a new server at work and I'm hoping to get ideas of how we should build it out for optimum performance and back-up capability. We have 6 drives and we need to have an OS (Windows Server 2008) and DB (SQL Server 2010). Everything is brand new, 6 x 146GB disk drives, 2 AMD 2.2Ghz Quad processors and 16GB of memory.

We have a program that continuously reads and writes to a SQL Database.
