After many many many many years I've finally decided to buy an external hard drive. Only I have no idea what I'm looking for or more importantly should be looking for. I'm only going to use the external HD to store my pictures and videos. Guessing that a 1TB HD will do the job. Looking at Best Buy quickly to see what is out there, I see this EasyStore 1TB for $50. Is that a good HD that will work for me? Best Buy also has a Mac specific HD for $60. Is one better than the other? Does the HD have to be Mac specific or will any HD do the job? Any brands I should stay away from? Thanks!
