Raid-Level and diskssystems?

Hi!
I Have been reading the white paper "Planing an Exchange Server 2003
Messaging System". One of sections discussed disk and storage configuration.
The sugestion was to separate System, transactionlogs and databasefiles into
different fixed disks and partions..I can see the advantage of separaing
them but I dont have the opertunity to make such a configuration.

My Idea from the beging was to make RAID-5 disk subsystem... but Iam not
sure if this is right anymore..This is the hardware I have:
2*500 MHZ
1500 GB of RAM
1 Raid-controller which is able to suport mirroring + some Raid-levels
5 diskcabinet ( 4 * 18,2GB + 1*9,1GB)
What is your sugestion to make the most out this..
My opinion is that Raid-5 system with one hot-sparedisk is ok..(skip the
9,1GB and buy a new 18,2GB as hotspare)
Which mean one logial-drive(54,6 GB) and then partioning it like this:
C: - 14,6GB = System and boot + pageFile (win2k3+E2k3)
D: - 25,0GB = Transactionlog-files
E: - 25,0GB = Databasefiles
Is this an acceptable solution?? Does Transactionlogfiles and databasefiles
need different amount of diskspace? Should the database partion be grater?

The total nr of users on the exchangesystem are nomore the 75...
simultainusly about 20-30...
