So easy to setup.

Reviewed in Australia on 1 January 2020

I had struggled with open media vault through a Raspberry Pi unit, the unit itself was good however the software side of the system lacks. The QNAP on the other hand is great, very easy to use and setup straight out of the box, heaps of great added features such as cloud sync is an awesome feature to help in the storage of key essential data. I would highly recommend this unit. Works great as a media server too using PLEX.

Thoughts for Buyers - Not always easy to check what it will do (or wont do) for you

Reviewed in the United Kingdom on 18 January 2017

Verified Purchase

Like some others, I've found the unit a little frustrating in places when compared to a Synology device. That being said, it still has many features my earlier Synology did not, so its very much swings and roundabouts here. These are first few weeks impressions.

As a TL;DR version, just review and make sure it does what you want before you buy it....

I have moved from a DS112+, which even though its only a few years old, and I purchased the + model, after DSM5 it became increasingly slow, DSM6 did not improve this, so I wanted a new device. Considered similar in the range, but was sold on some of the QNAPs additional features and promise. I should have perhaps done more research, played more with the public demos as I would have realised more of the limitations perhaps and MAYBE stuck with Synology.

As with other comments, it tends to work less well out of the box, or has teething issues. So far a few apps have struggled to work out of the box, which is frustrating, though I am sure I will be able to get them to work, but others who want it to just do it might find that annoying. You may also assume it does something, when it does not.

Storage Management/Control and Shared Folder not as "simple" as Synology, and you have less control over default locations, in some cases you seem to be able to change the default, but not remove the folder created, or in other cases have no control over the location (especially annoying when you don't Raid the drives and wanted something on Drive 2). Posts seem to suggest the answer is just "hide" these not needed folders them from network discovery. That's ground on the people asking as much as it does me, especially as some of these items should not even be set as shared folders in a Network sense.

I was hoping to run a Proxy on the unit, however like I mention, the seeming ease of the application doesn't do what it says, and I can only currently get the proxy to work as Open, or only to accept the Admin User/Password. Searching for online help etc didn't exactly help. Again, I am sure with tweaking, or forum posts I can get this to work, but disappointing.

Similarly I have quickly tried the Virtualisation Station, a feature that sold me on the device. It works and appears fine, but again, out of the box I am unable to use it as anyone but the admin user right now. Again, I am sure there is something I can resolve maybe, but grinds on me that I have to log in as the admin to start / stop the VM, and then connect to it etc.

The qVideo app I found was basically worthless compared to DS Video, which I always preferred over Plex because some of its limitations around licensing etc. I have been "forced" to use Plex now, but it performs very nicely on the unit (no setup issues that side for me thankfully). Re-Indexed my entire collection in mere hours, so long term I am sure I will live with this fact.

Entspricht nicht mehr "meinen" Erwartungen / Support finde ich nicht aussreichend

Reviewed in Germany on 5 October 2018

Also zuerst, das war jetzt meine 4 QNAP Station.
Sie war der Ersatz für eine Kaputtgegangene TS 419+, eine vier Bay Station. Sie ist nach einen Firmwareupdate nicht mehr gestartet. Ich schreibe dies im Vorfeld um später auf den Support eingehen zu können.

Ich muss beruflich viele Videodateien hin und herschieben, dies mache ich wie viele mit USB Datenträgern. Früher war ein Twonky DLNA Server auf dem QNAP, die ist jetzt nicht mehr mit dabei. Die war wunderbar und lief echt rund. In zusammenhang mit den restlichen Softwareeigenschaften, hatte ich nie wirklichen Grund mich zu beschweren und war Jahrelang gutzufriedener QNAP Kunde.

Mit der neuen QNAP TS-251+ gibt es aber keinen Twonky mehr, man muß Plex nehmen und seine Daten in die ganze Welt teilen, oder den internen DLNA Server. Plex hat die Filme immer wieder abgebrochen.

Wie oben beschrieben habe ich meine Daten auf USB Medien. Aber es ist mir nicht gelungen diese im internen DLNA Player einzubinden. Mehr noch die USB Geräte stürzten so ab das man den QNAP neu starten musste, sollte man diese einbinden wollen.

Das Forum und der QNAP Support haben es nicht geschafft mir zu helfen. Im Forum hatte sich in 4 Tagen niemand gemeldet, und der Support meldete sich innerhalb von zwei Tagen nicht. Und ich habe auch nicht vor länger zu warten, bei meinem letzten Problem mit meinem TS 419 hat der Support sich eineWoche Zeit gelassen bis er sich meldete und konnte mir auch nicht helfen eine kaputte Firmware zu reparieren, auch nicht Kostenpflichtig.
Das geht für so ein Gerät meines Erachtens nicht. Daten sind wichtig, der Support muss innerhalb von 24 Stunden reagieren, oder eine Kostenpflichtige Lösung anbieten.

Also mein Fazit :
Support mangelhaft
DLNA USB Support mangelhaft
Ersatzteile mangelhaft

Für mich in diesem Zusammenhang ist der QNAP nicht zu gebrauchen.
Wer Ihn nur als guten Fileserver betreiben will, dem Rate nich gute externe Kopien zu machen. An das Raid kommt man ohne QNAP nicht mehr dran. Aber solange er läuft. -> KLASSE

Ich steige jetzt um auf zwei Raspberry Pi's, den einen als DLNA Server, den anderen als Fileserver. Die erreichen zwar bei weiten nicht die Perfomance einen QNAPs, aber es gibt eine große Community die helfen kann. Mir reicht dies für einen Bruchtteil des Geldes. Ich verbrate zwar mehr Zeit beim Einrichten aber nicht soviel im Support.

Ich hoffe meine Erfahrungen helfen weiter.

Grüße und viel Erfolg

Surprisingly good!

Reviewed in the United Kingdom on 28 July 2018

So I wanted to a NAS for a number of reasons, those included;

1. Plex for my media library.
2. Remote Virtual Machines to run Linux.
3. Backups for all devices at home.

Now my main concerns were processor power for Plex connected to my 43" 4k TV and ram for the virtual machines.

The first thing I did was upgrade the ram, ordered an 8GB kit at the same time as the NAS at £63. So that fixed any concerns over maxing out the ram, although I do recommend upgrading it as 2GB is not great you will probably get by if you are not running lots of apps, especially virtual machines.

The processor you can't do anything with, it is what it is. Now for Plex, it recommends a processor with at least a 2k pass mark for a single 1080p video stream. The processor benchmark is 1861, not optimal but handles it fine, the key is to avoid transcoding whilst you watch however that is beyond this review. Plugged into my TV through the HDMI port it performs incredibly well and everyone is happy with the quality.

Other than that the device has many apps and it's quite easy to install, keep up to date and understand when it needs to be updated.

I am using 2 3TB Western Digital Red drives in the unit, performance is good and in the 6 months since I set up the NAS it has been running without a single issue.

So overall and with 6 months of use in hand I can honestly say it has been a great purchase and my concerns around it being powerful enough for my needs very quickly disappeared. Helped of course with a ram upgrade.

If there is anything I could pick at it is that it can be quite noisy when you are sitting watching something on Plex. Not overly but noticeable.

QNAP TS-251+-2G 2 Bay Desktop NAS Enclosure. Very Pleased

Reviewed in the United Kingdom on 13 June 2017

Verified Purchase

This was my first foray into having a Nas on my home network. I have quite good knowledge on networking and file sharing so i wasn't daunted by the setup prospect. My main purpose for the Nas was keeping all my files, films, music etc backed up in one place. Also for media streaming to the my rooms for the family.
Basic setup was reasonably easy considering I have never seen the UI before. I did watch a few youtube videos to get some helpful information.
It is now setup with Plex for my media streaming requirements and I have it say it hasn't missed a beat.
I can access all my files from My iPad/Iphone/Mac/PC from anywhere in the world. I use a OPENVPN configured on my router for security.
I was also able to configure some my IP CCTV cameras to record direct to the NAS instead of their SD cards. Again you can access the recordings anytime anywhere.
There a lots of other features on this NAS but I haven't found the time to explore all of them.
I did upgrade the NAS from 2gb to 8gB of memory(cheaper than buying the 8Gb one) and very easy to upgrade. https://www.amazon.co.uk/dp/B005LDLVAO/ref=cm_cr_ryp_prd_ttl_sol_2
I have the NAS plugged into the TV via HDMI but have not explored fully how useful direct access via the Tv is.
If your looking for a reasonably priced NAS for your home network then I have to say the QNAP does a great job.

Does the job, but not absolutely perfect

Reviewed in the United Kingdom on 27 May 2018

Verified Purchase

This is my first NAS, and I guess this review will only be useful for the first-time buyers like me.

First of all, it works, more or less as expected, providing access to my files through pretty much all possible means: SMB (Windows File Share), NFSv3, NFSv4, SFTP, FTP, HTTP, WebDav, ... basically everything you'd expect from a Linux box, but with the advantage of not having to spend much time configuring it, and much lower power consumption. For the things that are missing, there's Container Station, which supports Docker and LXC. Also it plays well with Chromecast and smart TV devices. So overall I'm pretty happy.

Now, some things aren't as good as I wanted them to be:
* Realtime transcode works, but has many drawbacks. It takes time to start playing or to seek. Seek functionality does not work in any player other than in-browser player. In-browser player is weak in many ways (no support for subtitles other than *.SRT, no support for loading subtitles from separate file, ...). Some of this is better with Plex, but not all that much. Most of this is more or less expected - they can't do magic. But eventually I gave up on realtime transcode completely and set up batch transcode instead. Bottom line: when choosing next device, I won't care much about the realtime transcode capabilities.
* Transcode is not flexible or configurable. For example, there's no way to specify the desired AVC profile and level. This means that if my goal is to transcode to the format that my Android tablet can decode using hardware decoder (which uses far less battery power, but also only supports lower AVC profiles), I can't do that. However the defaults are good for smart TV and Chromecast.
* AC3 audio encoding is not supported, supposedly for licensing reasons.
* No sensible GUI way to configure firewall - although it's doable with autoexec script. This matters if you want to make your NAS accessible from the Internet, and your router is too dumb to allow flexible firewall configuration too.
* No support for NFSv4 security with Kerberos. QNAP's NFSv4 is as insecure as NFSv3.
