Just got a Dell PowerEdge 2950 III. It came with four 15k SAS drives configured RAID 5 (hardware) with Windows Server 2003 loaded. I've got to run MS SQL Server 2005 on it and I also need to use the server for file sharing. I'm wondering if it would be best to reinstall Windows Server 2003 and MS SQL Server 2005 on a 5th drive outside the array and just keep the SQL Server data and logs on the array, and use a 6th drive for all of the shared folders? Hoping to have 50 users on this one Dual 3ghz processor, 8-core server. Would doing all that improve performance much?
