This sounds like a test question. Here's how I'd do it: "C" drive = 2 x 18 mirrored "D" drive = 2 x 36 mirrored "E" drive = 8 x 72 RAID 5 (or) "E" drive = 4 x 72 RAID 5 x 2 (RAID 5+1, that is mirrored RAID 5 drives) The last option is the most secure, and costly, cutting your possible database storage in half, and is probably a little over the top for your needs. Install your system and boot files on C, Exchange logs on D, private and public databases on E. Drive lettering for D and E could be interchangeable.
