I don't know about this specific model, but I've already installed a few Synology NAS'es and up to this day they still perform flawlessly. When it comes to NAS'es I would only buy Synology or Qnap (or maybe Infrant/Netgear, but those are REALLY expensive). I don't think you can go wrong with either brand.
