QNAP TS-509 Pro

5 December 2008
  • Summary: The QNAP NAS devices use mostly the same firmware, if you like one you'll like the others. Features that actually separate the models come in the hardware and the (storage) expansion options. We already knew the firmware is easy to use and full of features, there wasn't a doubt there.
  • Pros: High performance, Feature rich, Easy to use, Built-in power supply, Plenty of external connection options, Highly moddable, Configurable without PC
  • Cons: Expensive, Slower with huge files

25 September 2008
  • Excerpt: It's rare to come across a product that exceeds my expectations as much as this NAS did. Even excellent products usually have some minor issue that I come across during a review, but it was difficult to find anything negative at all to say about the TS-509.

QNAP TS-509 Pro

3 July 2009

iSCSI: Ver weg en toch dichtbij

9 August 2009
  • Excerpt: Het gebruik van netwerkopslag biedt verschillende voordelen. Toch is het systeem niet voor willekeurig welke toepassing ideaal, omdat de rechten en plichten op een netwerkbron worden geregeld door de host. Dat maakt een netwerkbron minder flexibel qua gebruik dan een gewone harde schijf.
