Quick steps to move the temp table to a different hard drive. USE master;GO
ALTER
MODIFY FILE (NAME = tempdev, FILENAME = 'e:\dbroot\tempdb_sqlservernew.mdf');GO
ALTER
MODIFY FILE (NAME = templog, FILENAME = 'e:\dbroot\tempdb_sqlservernewlog.ldf');GO
Reason to do: To improve system/IO performance. Almost all the transactions like sorting, swifting and collation done by SQL Server uses this temporary table. Preferably it should be on a RAID drive.
