While the Gig-E port of the DroboPro only supports iSCSI, this new model supports AFP, CIFS, and SMB protocols. There is also a new feature called DroboApps, which can be installed to add things like iTunes server functionality, cloud backup (via Oxygen Cloud), and even BitTorrent support.
A recent update to the Drobo Dashboard software included support for the Drobo FS. This means a single software package will work across the entire Drobo like of products:
While the new Drobo FS is a welcome addition to the line, it should be noted that SMB over Gigabit may be faster than the 100 Mbit DroboShare, it’s nowhere near as fast as iSCSI over Gigabit as found on the DroboPro and DroboElite.
