I have a brand new server that I'm preparing to use as our Exchange 2007 server.  I want to be sure that I configure it with the optimal RAID configuration (for speed) so I'm not kicking myself later.  I've gathered that I should stay away from RAID 5 all together.  The rep who sold me the server also runs his own hardware consulting business and swears to me that I should make all 8 drives (146 gb each) a single RAID 10 array and create logical drives for the OS, Database and Logs.  I'm uncertain about this.  It seems to me that I should at least separate the OS and put it on a hardware RAID 1.

Something along the lines of:

OS = 2 drives in a RAID 1
DATABASE = 4 drives in a RAID 10
TRANSACTION LOGS = 2 drives in a RAID 1

I guess that would only leave me with the option of leaving the paging file with the OS.

Any advice?
