ADO.NET Entity Framework / LINQ on Visual 2013

Is it suitable to use ADO.NET Entity Framework / LINQ to access large SQL data (say ~ 1TB) as I afraid it will an additional layer before accessing the database which will slow down the performance ? Any comment ?

I don't think so. It is not advisable to use LINQ queries for large data. The main disadvantage of LINQ query is that there is NO cache of execution plans as SQL SPs do. Hence there would be impact in performance. My suggestion is don't go with LINQ for TB amount of data.
What sort of data is it? Is it mostly contained in 1 table?

No, 4 or 5 tables at least... Tks

BTW, what's the best approach to handle large amount of date retrieval with VB.NET ? Can you give me some idea / examples so that I can go for the right approach of programming ?

Again depends on the use case and what you intend to do with retrieved data. If you intend to display it in a control such as grid then it makes sense to use SQL to pull that data. Entity framework, as the name suggests, is more useful when you are dealing with entities in your code.
