The D-Link DNS-320L also has the option to sign up to MyDLink in order to access files from the NAS anywhere in the world. After a simple registration process, the web interface becomes available and is very easy to navigate, and download and upload files to the device. There is also a very useful "MyDlink Access-NAS" app on an Android or iPhone that can be downloaded for free, allowing backups of material from a phone or the ability to access files stored on the NAS. You can also stream music from the device straight to the 'phone with the built-in media player within the app (depending on the speed of the data connection) and even set the app to automatically save photos taken with your 'phone's camera straight to the NAS. Handy!
