I did a bunch of research before buying this little guy. All in all I can say that I am very happy with the features and options he has. I will preface by saying I'm not a super power user. I know basic linux and ssh usages, but stick to normal GUI interface controls. I also purchased 8GB of RAM separately, because paying the price to have it come shipped with it was a little ridiculous.

- 1TB WD external hard drive via USB to store miscellaneous media files
- HP All in one printer shared to the network via USB
- IP Address using an IP reservation policy on my router (this is important, see cons)
- Implemented a LetsEncryt SSL certificate and hooked it up to a subdomain on a domain I already own. Accessible from anywhere.
- Private VPN using the QNAP VPN client for Windows 10 and iOS devices.
- Many QNAP and third party apps are supported.
- Plex Server works great to PS3, Xbox 360 and iPhones. Transcoding 1080p videos is pretty seemless.
- The QVideo, QFile, QPhoto etc apps for the iPhone are super convienent. Transcoding to these from the NAS works very well too.
- Great read/write speed on my network for my current needs
- Easy to use private VPN out of the box for Windows 10 and iOS devices
- Supports native LetsEncrypt SSL certificates
- The Virtual Workstation feature is pretty amazing for running a Windows PC on the NAS.
- Setting up users and group permissions was simple
- Very easy to navigate user interface. The look and feel is very sleek.
- Plug in play sharing of my non networked HP all in one printer was a sinch. Scanning took some time to be able to setup, but in the end it works pretty well
- I had an issue were almost every other day the NAS would lose it's IP address on the network. In HD Station from the HDMI out the IP address would be blank and the green status light would be off. The only way to fix it was to unplug and replug and ethernet line back in to the network switch it was attached to. After I setup an IP reservation policy on my router based on the NAS MAC address, this issue has seemed to go away though. Was very aggravating for a while though.
- Every now and then Plex Server seems to stop working. I have to restart the NAS and then it will start working again.
- Download Station doesn't work too well for private trackers. Use Transmission instead. It has much more features too.
- I feel like a lot of the default security options were a little too open. Google "QNAP How to make your nas more secure" for a QNAP post on closing some of these down. It's a good getting started guide to fixing some of the simple issues.
QNAP pumps up the hype in ways such as a header at the top of its OS pages, calling itself “QNAP Turbo NAS”. A more accurate title would be “QNAP Slow-Mo NAS”.
Its ONLY redeeming quality so far is a reasonably high transfer rate. I’m getting around 90-100 MBS on file types such as music and movies. That’s the best thing I can say about it.
Really sad, as I had high hopes for this NAS. My old WD EX4 was an absolute piece of garbage, literally, as it self-destructed and turned into landfill waste in less than four years. But so far this QNAP TS-451+ isn't much of an improvement. I guess I'll be stuck forking over more cash to upgrade the RAM from 2gb to 8gb to see if that helps. Too bad QNAP didn't make a fully functioning unit out of the box. Shameful.
When it reboots, you watch the minutes go by because booting takes at least 5 minutes. Because that hour+ didn't install any apps, you then start the process of trying to install those. The first app install froze the machine and required a reboot (5+ minutes). Not a single app would install after that. You may spend 10 minutes watching the downloading screen only to see the screen flash and get a brief "installation failed" message. No explanation for why the install failed or what to do. Rebooting does nothing, trying to install other apps does nothing... This thing cost as much as a mid-priced desktop PC - the basics should function out of the box even if they require updates.
QNAP support wanted me to pay to ship to them, pay a $100 labor fee plus parts estimated at $41 assuming it was the backplane and then I would have to also cover the return shipping. That's over half what I paid for the NAS to repair it just 1.5 months past the 2 year warranty. I don't think it's unreasonable to expect a product to last a ways longer than the warranty period, especially given the cost of this NAS. Im capable of replacing the backplane myself but support was unwilling to sell me the part.

Just a overall crappy experience from buggy untested software to horrible customer service. I was yelled at over the phone for having upgraded the unit's ram.
Do not waste your time with QNAP. Get a Synology instead. Learn from my mistake.
If you are using it as a file or cloud NAS, it's fairly powerful. The back up app features are fairly straight forward and if you are using the NAS as a target to backup, that is fine as well. You will need to mount one time and login each time you reboot your computer/laptop.
If you are using it as a media server, here is my comment. I skipped the native sw and used Plex. It works with 1080p. Takes a little bit of time for the system to offline transcode... so if you have a lot of files, it may take a couple of days to complete.
I went with the minimum config. TS-251+ 4GB with WD Red. Runs fairly quiet and very low in heat. Wired gig for now, attempting a wireless USB NIC over the holidays.
