After more than a month in beta state, Synology's final latest version, version 4.1, of the DiskStation Manager operating system for its NAS server, was released today.
Synology is one of a few NAS vendors that regularly releases new versions of the operating system, which improves and adds features to its existing NAS servers. DSM has been by far the most advanced operating system for network-attached storage servers, which offers not just a vast amount of features and ease of use, but also the most robust user interface that resembles a native operating system. Like all NAS operating systems, DSM is accessed via a Web interface using a connected computer.
The new version offers some major additional features to the already feature-rich OS, including a Video Station and mobile apps for Windows Phone 7. The Video Station allows users to organize their movies and adds support for USB digital TV tuners. Users can also stream videos and recorded TV programs to standard network media streamers. Synology's mobile apps, including DS Audio, DS Photo +, and DS Finder, have been available for iOS and Android devices. Version 4.1 of the OS will bring this support to Windows 7 Phone users.
The new DSM 4.1 version will also include improvements for the Audio Station (better design), the Cloud Station (now supporting two shared folders), the Photo Station (now supporting timeline and faster thumbnail creation), and the Surveillance Station (refreshed design).
In addition, version 4.1 also refines and adds more business features to the server, such as making the NAS compliant with VAAI (vStorage APIs for Array Integration) and offering RAID Fast-Rebuild Technology, Mail Server Enhancements, and support for authentication security with NTLM v2 and Kerberos v5.
