    Below is some difference between Clustered and Non-clustered in SQL Server:

    1. Clustered Index

    - Only has a clustered index in a table.

    - It's created on the primary key.

    - Data retrieval is faster than the non-cluster index.

    - Sort the records and store them physically according to the order

    - Do not need extra space to store the logical structure.

     

    2. Non-Clusted

    - Quicker for insert and update operations than a clustered index.

    - Can create many non-cluster indexes in a table,  the maximum of 999 non-clustered indexes per table as per limitations.

    - Use extra space to store the logical structure.
