I was tossed between the WD 1/2tb Caviar blacks and a Samsung Spinpoint f3 1tb drive. For the price of admission I decided to go Samsung. I'm thinking of just adding it my main rig as a mulitmedia drive (music,movies, video). I'll then format both 1tb external drives and use those as backup instead of media drives. Any contradiction to this? Anyone using those Spinpoint F3 7200rpm drives/thoughts? I'm guessing Sata 3 drives should be faster vs USB 2.0 external drives correct?
