Is TempDB stored in memory?

This is good news, though, as logically, memory is the smart place for TempDB to reside. The less we have to manage, the better, and the fewer data churn that SQL Server needs to perform while caching data to TempDB, the faster our workloads can execute.

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.
