Can I move tempdb?

Can you move TempDB files location without restarting SQL Server services?

As far as I know, there's no way to move TempDB without stopping and restarting SQL Server. You can execute the script, but the change itself won't take affect until SQL Server is restarted. You don't have to restart the file server, just the SQL Server service which will minimize your downtime.

Is it safe to shrink TempDB?

In SQL Server 2005 and later versions, shrinking the tempdb database is no different than shrinking a user database except for the fact that tempdb resets to its configured size after each restart of the instance of SQL Server. It is safe to run shrink in tempdb while tempdb activity is ongoing.

Should TempDB be on its own drive?

By default, the TempDB files are put on the same drive as the SQL Server binaries. Even if the user chooses a custom install, TempDB still goes on the same drive as the other data files, and that's not a good idea either. Instead, the TempDB data files should be on their own dedicated drive.

Does TempDB affect performance?

Although this may be true on smaller, less active SQL Server instances, tempdb can significantly affect SQL Server's performance. DBAs can act to ensure that tempdb performance is optimized and to optimize the overall performance of SQL Server.
