Data Space Configuration

I have to create a test instance, and I have 8 gigs of space to work with. I have to do this on 2 different servers. On one server, there is 4 gig available on 2 separate logical drives, and on the other server, there is 8 gig on 1 logical drive. Hardware RAID is used (but I am not sure whether it is RAID 5 or RAID 0+1). Which would be a better configuration: 4 2 gig chunks allocated into a "test rootdbs" with the physical log, logical logs and data all together. or 400 meg root 200 meg physlogdbs 2 tmpdbs's @ 700 meg 2 gig llogsdbs (for logical logs) 2 2 gig chunks for datadbs Please provide me any input you may have.
