Storage provisioning for Microsoft SQL Server
A back-of-the envelope "guess" would be to put the log files on one drive, the data files on another drive, and in the case of prod, put the tempdb files on a third drive.  You should also consider a location for SQL Server backup files that is not on the same drive subsystem as either your data or log files; preferably an off-machine location.

Having said that, you've provided too little data for us to really help you decide on the highest performance setup.
