Microsoft have a document you should read: "Optimizing Storage for Microsoft Exchange Server 2003" http://download.microsoft.com/download/b/e/0/be072b12-9c30-4e00-952d-c7d0d7bcea5f/StoragePerformance.doc
Microsoft also have a utility "JetStress" which you can use to verify the performance of the storage system. http://www.microsoft.com/downloads/details.aspx?familyid=94b9810b-670e-433a-b5ef-b47054595e9c&displaylang=en I think you can use Jetstress on a non-exchange server if you copy across some of the Exchange DLLs. If you do any testing along these lines, please report success or failure back to this forum, and on the 'Storage-discuss' forum where these sort of questions are more usually discussed.
