Should i get a 2tb 5400rpm HDD, or a 1tb 7200rpm HDD?

Lets face it, unless you are a computer programer or somthing that you need to have an insane amount of space, you dont need 2tb but also rpm bearly makes a difference, so it basiclly matters what your doing on your computer, forget about rpm and ask yourself if you'll need 2tb, if you dont then get the 1tb
