Today, nothing else will work without an external hard drive. The first is not a major problem, because memory is not more cost the earth. It is therefore all the more important a good piece to protect. The bag has proved to be extremely useful, unites them but the best qualities: a certain strength without being too hard, very beautiful appearance and the matching interior. I can highly recommend. The only drawback is, that the shipment in about as "expensive" as the actual product ?!
