Let me start by saying that the contents of this post is not very advanced.

Is it quicker and/or lower overhead to insert into a heap vs. a clustered table?I don't know. So I decided to do a test. Some background information first:

Within your SQL Server environment there are few simple steps you can take up in order to gain performance to a level, for instance when configuring a SQL Server that will only contain a few gigabytes (GB) of data and not sustain heavy read nor write activity, it is not as important to be concerned with the subject of disk I/O and balancing of SQL ...

You may be aware that the indexes on a SQL Server database take up space, so in case of unused indexes its obvious that they waste storage. It is easy to find the indexes using SP_HELPINDEX statement against a table, so to identify the unused indexes what is the way out.
