Such a table is usually physically pre-sorted according to its clustered index key. If a new row is inserted in the middle, data rows are physically moved to make room for it. So it's not a good idea to cluster index a table by a column which is not sequentially input. This allows queries to be answered without the time-consuming task of sorting.

To speed up the random retrieval of data pages, clustered indexes are created and stored on index pages apart from the data pages so that sorting is performed on pointers to the data instead of the entire data pages.

Clustered indexes are organized using a technique called B-trees, which are depicted visually as a triangular upside-down tree like a pyramid. The top node of the B-tree pyramid is the sysindexes. A lookup traverses the Intermediate nodes in the middle. Pages containing data are called leaf nodes at the bottom layer.

To avoid the need to shuffle index pages, indexes are built with only a percentage full. This reduces space usage at the expense of time for page splits during inserts and updates.
