The update includes many important features, such as Synology Cloud Services for seamless syncing between devices as well as Antivirus Essential, a virus scanner.
There is also a QuickConnect option to sync data without port forwarding. Furthermore, unlike licensed cloud services, Synology’s doesn’t have recurring fees.
There are also various new and improved administrative tools such as iSCSI LUN backup software, enhanced ADS/ACL support, flexible notification system, improved Apple support and scheduled SMART scans. Of course, old favorites like Download Station and Photo Station are included too. Download Station 2 turns the DS1512+ into a 24/7 download center for BitTorrent, FTP, HTTP, eMule, NZB news server, RapidShare and MegaUpload. Even shutting down your computer won’t affect transfers, as files are downloaded directly to the NAS device.
Another cool application is Photo Station 4, which comes with advanced photo wall and image flow browsing options. In addition, the flexibility of photo theme customization, visitors’ privilege settings to view or upload photos, virtual albums of recently uploaded images, RSS feeds, and a 3D photo browsing of Cooliris, make this the ultimate photo sharing center on the Internet. 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.
