The physical data independence is basically used to separate conceptual levels from the internal/physical levels. It is easy to achieve physical data independence. With this type of independence, user is able to change the physical storage structures or the devices which have an effect on the conceptual schema.

Logical Data Independence is used to change the conceptual scheme without changing the following things :
