What customers say about "Features"
QNAP TS-473 4-bay NAS
  • Many nice apps and user licenses for video surveillance, Hyper Visor integration, Photos, Cloud, File sharing ETC.
  • Unbelievably rich interface operating system. FAST. Very capable for it's size.
  • You really need this 473 to transcode 1080p video without any lag.
  • This is the most full featured NAS I have used.
  • The QNAP DLNA server just plain didn't work with my 3 DLNA devices.
QNAP TS-451+ 4TB NAS Solution
  • Setup was pretty good and worked straight away. But pretty fast, once up and running you are left to make a lot of decisions abut what apps to load, difficult quaetions about transcoding and so on.
  • Media streaming seems good, which was one of the reaosns I chose it, I like the web-baed interface, it is responsive and pleasant.
  • I have it running a VM, Plex, iTunes server and a bunch more stuff on top of it's network sharing duties and it doesn't break a sweat. It has a web interface which is one of the best I've used.
  • Set up was a very straightforward affair, just be patient as formatting and scanning had take time. Once loaded on installed it can be augmented very easily with the excellent apps. Highly recommend this product.
  • Trays feel somewhat cheaper and more plasticky than those on my older 219 NAS, but not a major issue as they should remain in place for most of their life.

What customers say about "Interfaces"
QNAP TS-473 4-bay NAS
  • It will handle hitherto unheard of quantities of data at amazing speeds.
  • The high speed built in lets it effectively handle the tasks I used to need my desktop to perform.
  • Great storage solution. Great connectivity. Great LAN speed.
  • Has LCD multi-line information display, USB backup port, fully configurable settings. Excellent for me.
  • Data access speeds and RAID rebuild times are quite slow as compared to the old Linux box this is replacing.
QNAP TS-451+ 4TB NAS Solution
  • Easy to setup and data transfer rates good.
  • A very well designed machine that is easy to install. Set up, software wise, is more difficult and I had to contact QNAP support for advice.
  • The interfaces are simple to use (however sometimes I get lost because of same functionality distributed in multiple places).
  • Also the gigabit connection through my router made copy over 90GB of data in a few hours. I had some misunderstandings at first, but the QNAP tech support was great in helping me out.
  • I have it connected via HDMI to my living room 4K TV and having the remote was a nice add on. Im impressed with all of the free apps that are available to expand functionality.
