SN	B Tree	B+ Tree
1	Search keys cannot repeatedly be stored.	Redundant search keys can be present.
2	Data can be stored in leaf nodes as well as internal nodes	Data can only be stored on the leaf nodes.
3	Searching for some data is a slower process since data can be found on internal nodes as well as on the leaf nodes.	Searching is comparatively faster as data can only be found on the leaf nodes.
4	Deletion of internal nodes is so complicated and time-consuming.	Deletion will never be a complexed process since element will always be deleted from the leaf nodes.
5	Leaf nodes cannot be linked together.	Leaf nodes are linked together to make the search operations more efficient.
