What should I do to use my hard drive on a Samsung Tablet?

I have a 2 TB hard drive full of movies. I am getting bored watching movies on the computer so I decided buy a Samsung Galaxy Tab. My hard drive is NTFS and my friends told me that I have to convert NTFS to exFAT to able to see my files on the tablet. My question is, if I convert my hard drive from NTFS to exFAT, will I be able to watch the files on the tablet? If not, what should I do to be able to do so?
