Hello. So I'm looking for a new 1TB External Hard Drive USB 2.0 to use with my 2011 MacBook Pro running Sierra 10.12.6. From what I can tell on Google/Amazon etc, the Seagate Expansion 1TB and the Maxtor 1TB are the best Portable drives at the moment. Which one would be the best to go for? If I understand correctly I'd have to reformat them both anyway. Thanks for your help.
