I want to buy a 2nd hard drive for my computer as i have filled 80gb with films/music etc. I have seen a 160gb on ebay for £40 but they say they cant specify 5400 or 7200 rpm. 
What difference would it make and since i only really need more memory to store more films would it be a problem to get 5400 rpm?
