DSM 4.0 sports a revamped user interface and new features such as widgets.
There is also a QuickConnect option to sync data without port forwarding.
Furthermore, unlike licensed cloud services, Synology’s doesn’t have recurring fees.

Synology is launching two of its popular mobile apps on Android tablets: DS file and DS photo+.
DS File lets you browse through DiskStation files on a bigger screen and make changes instantly.
Those with Amazon’s Kindle Fire will benefit from full mobile support using the latest Synology Kindle mobile app.
Of course, old favorites like Download Station and Photo Station are included too.
Even shutting down your gear won’t affect transfers, as files are downloaded directly to the NAS rig.
Another cool software is Photo Station 4, which comes with advanced photo wall and image flow browsing options.
Additionally, the newly-added Google Maps integration lets you geotag your photos and trace your path.
Between its sleek interface and gobs of features, we think DSM 4.0 is the best NAS software around.
