Final Thoughts & Conclusion

The TS-509 Pro has more to offer over the TS-409 Pro and TS-409U. In addition to a fifth hard drive bay, the TS-509 Pro also offers better UPS support, eSATA support, and more USB ports than I'd ever need on a NAS. The eSATA and USB ports both offer the easy ability to transfer files to and from external hard drives, while the USB ports can also be used to share printers across the network.

The 1.6GHz Celeron in the TS-509 Pro is much more powerful than the 500MHz CPU found in the TS-409 series, and the TS-509 Pro also features a full gigabyte of RAM. The increased speed and memory leads to better network transfer speeds over the HTTP, NFS, and SMB protocols. The TS-509 definitely deserves the "Pro Turbo NAS" moniker, as performance all around is boosted up to two times more than what the TS-409 series offered.

With its new features and improved performance, the QNAP TS-509 Pro Turbo NAS packs a serious punch. In addition to the new features and improved performance, the TS-509 Pro also features a failsafe DOM archictecture. This not only simplifies set up, but also safeguards the unit against failure.

Honestly, QNAP has made the TS-409 all over again, only better. I'm in love with the unit, and the only thing I can honestly say I dislike is the web interface. The interface is unchanged from that of the TS-409U and earlier models. It isn't horrible, but navigation can be slightly difficult from time to time.

Don't be mistaken: this may be as good as it gets, and it's damned good.


  • Simple installation and setup
  • Feature-packed
  • Exceptional performance in HTTP, NFS, and SMB transfer speeds
  • Plenty of backup options


  • Expensive
  • Web interface isn't very intuitive
