Many of these features could also be found in the TS-409U, but one of the new features that excites me the most is the "DOM Architecture with Embedded Fail-safe Dual OS". From QNAP's website, the description of this is, " All the OS and applications are embedded on the DOM. The TS-509 Pro allows system booting without accessing the physical disk sectors and that prevents unsuccessful system startup caused by bad block sectors or file errors on the hard drives. Two operating systems are built on the DOM for system booting alternatively upon every system startup. When one fails, the other one will be used to boot up instead, and the failed OS is recoverable from the other healthy OS.

These relieves the issue of HAVING to use QNAP's software to load firmware on to the unit after the RAID array has been creating, which was the case with the TS-409U. It's this feature that allows for the PC-less installation. Very nice touch, QNAP.
