The below are the major differences between Clustered and Non-Clustered Indexes .

S.No	Clustered Indexes	Non-Clustered Indexes
1	Clustered Index  reorders the physical storage of records in the able	It sorts and maintain a separate storage
2	There can be only one Clustered index per table	We can have 249(before 2008) ,999 (from 2008) non-clustered indexes in a table
3	The leaf nodes contain data	The leaf node contains pointer to data
4	To create clustered index SQLServer required more memory because the leaf pages in the tree structure will maintain actual data .	To create non-clustered index Sql server requires less memory because the leaf pages will contain pointers to actual data.
5	By using clustered index retrieving data is more faster,when we compare with non-clustered index.	By using non-clustered index retrieving data is slower than clustered index.
