After having analyzed this TechNet article http://technet.microsoft.com/en-us/library/cc298801(office.12).aspx regarding Physical storage recommendations (Office SharePoint Server) I have decided to create a post related to tempdb.
Here you have a list of actions that you can apply on tempdb
1. Check where temp db is located
SELECT name, physical_name AS CurrentLocation
FROM sys.master_files
WHERE database_id = DB_ID(N’tempdb’);
