QNAP TS-451+-8G 4 Bay Desktop High-performance NAS Enclosure - 8 GB RAM, Intel Celeron 2.0 GHz Quad Core Processor - Supporting HDMI, Transcoding and Virtualization, Black

I've upgraded from a Netgear RreadyNAS, and also, I took the option of build my own, ie. I source the drives and memory separately (it's cheaper!), but obviously, have to spend a bit time to build the unit, took about an hour, so wasn't too long. First, this is very quiet, no more white noise humming in the background, just the occasional disks activities, so great! The software is very good, it's basically a linux unit, so you can do a lot with it, or not. I've chosen to use it as NAS with some of the built-in functions, but most others will be running in an Ubuntu VM in the NAS. So this VM is my home server, running mail / web etc. and it will start automatically when the NAS boots up. If you are not a technie, it's confusing, 'cause there are a lot of options & setup, and I've noticed, if some of the services are not working as expected, restart them. Overall, great piece of kit, does everything I want and more!

If you are looking for a NAS box, then it is a complex activity, that the QNAP makes more difficult by being more than just a simple NAS drive. As a NAS drive performance seems to be good, but it I am spotting issues moving small files from one part of the drive to another. Setup was relatively easy, complicated by my laptop running a company managed local firewall, which I had to disable briefly to be able to talk to the box. Also would recommend that you lock the IP address from your router to the QNAP, it will save you time and reduce effort. The QNAP isn't however, just a NAS drive. It is also a media server, with built in music and video capabilities and far more. The problem is, some of this capability isn't that easy to use and setup and the help files are pretty poor, in my honest opinion. So, music and internet radio is really easy to setup and move music from your laptops to the NAS box (make sure that you have your metadata sorted out, especially on compilation albums, otherwise it will not come up properly). however, some features that you will find on other music systems (like Bose for instance) aren't there, so being able to separate your music from that of your kids for instance is not that easy to do, as yes you may like some of their stuff, but equally, you will not want to get 20 songs of theirs when you are on shuffle!!! Video play back, I am having problems with. I have video's, but when I move them to the QNAP, the quality drops significantly and I am still trying to fix this. This box is powerful, but the power is being impaired with poor help

What can I say. What a monster of a little machine. Very solidly built. Fantastic OS software that is frequently updated. Very easy to setup. Has the great addition of a HDMI cable to plug into a TV or monitor. I was very surprised that it has an easy to use app store with loads of free software that turn this puppy into things you could only dream of. Very stable and after a months usage it have never been unavailable or busy on my LAN which has been a common trend for other cheaper underpowered devices I have had in the past. I decided to go for the QNAP instead of a Synology and spend the money I saved on extra RAM and HDDs. So far I really have nothing negative to say about this very solid, well thought out, professional kit. It has already saved my bacon when I had to do a complete restore of one of my PC system drives. Buy with complete confidence because it is money well invested.

Works very well. Very happy with this purchase. Bought this after a disastrous accidental deletion of all my movies, songs and photos on my external drive (thankfully recovered them back) - but this was definitely the time to invest in a proper NAS. Have spent probably years looking at NAS setups and never making a decision, then saw this and was sold. I have been searching for something that can properly run PLEX media server with transcoding for our home theatre setup, and this really does work. It has ran simultaneously 2 x 1080p transcoding sessions and not broken a sweat, which is really saying something for a NAS. Remained almost perfectly quiet throughout also! Can be used as a home media system in and of itself with the HDMI output and included remote control, although we prefer our Apple TV setup with streaming. Integrates well with our network with no hassles, and on the whole the software is not difficult to use (although it would be nice to have a better search options on it). If yo are after a cheap-ish NAS for PLEX then this is definitely the way forward.

This is the second one of these I have purchased. They do what it says on the tin. Nice and reliable. The market place option made it a no brainer.

The unit itself is well put together and has good features. It can even (unofficially) be upgraded to 16GB of RAM. However the Intel processors used in these units (Celeron J1900) have numerous hardware bugs that were never fixed. After a period of time, this causes the unit to fail prematurely. Google : intel celeron j1900 LPC clock bug for more details.

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. Good news if you know what you are doing, but after paying a fair amount of money for the box and the disks, you don't want a naggign fealing you are not using it fully. Media streaming seems good, which was one of the reaosns I chose it, I like the web-baed interface, it is responsive and pleasant. Not getting the same throughput as my previous netgear device, but unlike the netgear it has not crashed. Have not used it as a personal cloud yet.

Tras recibir el NAS QNAP TS-251+ lo configuré usando mi PC,fue rápido y el resultado positivo.Después he conseguido un cable HDMI suplementario y lo conecté a un monitor para ver como funciona con HybridStation ,allí descubrí que no siempre sale el sonido y que la QNAP tiene problemas de sonido al enchufarla directamente a un monitor !!! Tengo el último firmware instalado y lo intenté con otros cables HDMI pero el problema persiste :(

Bien

Wir nutzen das NAS für eine Firma mit vier Anwendern. Es löst seinen Vorgänger, eine Buffalo Link Station, ab. Diese hatte mit Gigabit Verbindung eine Leserate von maximal 25Mbyte/s erreicht. Mit dem QNAP sind nun über eine Verbindung bis zu 115 MByte/s locker möglich. Durch Portbündelung (zwei vorhandene Netzwerkanschlüsse) kann hier mit einem entsprechenden Switch und Aggregation die Rate noch deutlich gesteigert werden. Die Performance ist absolut spitze, die Einrichtung für einen Fachmann mit genügend Einstellmöglichkeiten vorhanden. Da ich das erste Mal die Benutzeroberfläche von QNAP benutze, muss ich hierzu noch sagen, dass die Einarbeitung aufgrund der intuitiven Bedienung sehr leicht fällt und dank der kontextbezogenen Hilfe sämtliche Fragen schnell geklärt sind. Von der Haptik und Optik ist diese kein Vergleich zum alten Buffalo NAS. Ich kann das neue System uneingeschränkt für kleinere Business-Anwendungen empfehlen. Virtualisierung, Server und andere Apps, wie die Surveillance Station, machen aus dem System einen sehr harten Gegner für einen koservativen Server.

Ich kann einige negativen Rezensionen nicht nach vollziehen. Die NAS (2-bay) läuft mit 2 10 TB HDD's WD-RED. Geräusche sind kaum wahrnehmbar. Die Spiegelung verlief recht schnell. Datenübertragungsrate im Home-NW liegt so um die 120 MB/s. Das ist schon recht schnell und ausreichend. Es gibt viele Apps die man nicht unbedingt alle benötigt. Mein Schwerpunkt liegt im Multimedia-Stream (Audio/Video). Zudem nutze ich sie als Backup- und Fileserver. Mehr Funktionalität benötige ich nicht.

Ich nutze dieses NAS natürlich zur massiven Speicherung von Daten. Es ist schnell, es ist super verarbeitet, leise und kompakt. Besonders die Möglichkeit einer VM auf dem Gerät laufen zu lassen, ist beeindruckend. Es ist besonders leicht, extra RAM zu verbauen, so dass man in wenigen Minuten mehrere hundert Euro sparen kann. Beispiel: Ich habe dieses NAS (mit 2GB RAM) gekauft. Dazu habe ich den passenden RAM gekauft und selbst eingebaut: https://amzn.to/2FfsIFM . Dazu muss man lediglich 12 Schrauben lösen. Das ist wirklich leicht. Zusammen mit den 4 passenden Festplatten, z.B. diesen hier: https://amzn.to/2HuiKCb hat man ca 11 TB im RAID 5 Verbund zur Verfügung. Und zusammen mit dem Amazon S3-App auf dem NAS kann man seine Daten regelmäßig, verschlüsselt ins S3 wegspeichern. Läuft super und zuverlässig. Wirklich toll ist die Funktion der VMs auf dem NAS. Das ermöglicht zusätzliche Computer im Netz, ohne extra einen PC zu starten. Die VM kann dann sogar per HDMI eine Ausgabe auf z.B. ein TV-Gerät ausgeben. Android in der VM und viel Spaß!!!!
