5.0 out of 5 stars Cost effective QNAP RAID expansion with alternative use as computer attached storage
(function(){ P.when('cr-A', 'ready').execute(function(A) { if(typeof A.toggleExpanderAriaLabel === 'function'){ A.toggleExpanderAriaLabel('review_text_read_more', 'Read more of this review', 'Read less of this review'); } }); })() This is effective QNAP NAS RAID expansion (no disks included) with great alternative use as computer attached storage (if you are not wanting a remote standalone NAS). QNAP products are very reliable and long term supported with software upgrades.
5.0 out of 5 stars Easy expansion
Fast and easy expansion for a QNAP NAS or a computer. Easy to fit HDD.
4.0 out of 5 stars Cheap way of building a hardware RAID
This is sold as an expansion caddy for a QNAP NAS – but I'm using it as directly attached storage for my home server. It functions perfectly well as an external caddy, and provides a little more functionality than a standard 4-bay external caddy, at a price that's competitive with other reputable brands.The Interface is USB-C, so it's pretty straightforward to connect to a PC or Mac. There are dip-switches on the back that allows the user to select between RAID 0, RAID 1 and RAID 10 – or leave the caddy in JBOD mode, so your computer recognises individual disks inside.I was a little wary of this – assuming one false move with the dip-switches would wipe everything – but after moving the switches, you still have to press and hold a button before anything useful/calamitous can happen. The buttons and switches are nice and sturdy, so there's no danger of doing anything accidentally.There's a big 120mm fan on this, which means it turns a little slower and runs a little quieter than on units with an 80mm equivalent. It's doing a good job of keeping everything cool. Running with minimal load, the 4x12TB WD CMR drives I have inside are running at 35°C for slots one and four, and 37°C for two and three. Setup as RAID 0, when copying 32TB of data to the drive, temperatures peaked at 55°C (S.M.A.R.T status) is viewable through the QNAP external RAID Manager software that comes with the device.I've had not particular problems with that. It did have a crazy day of going off-line in 12-second bursts four or five times. Can't figure out what caused that, may have been nothing to do with the unit – but it's been up now for two months and, that day apart, has ran like a sewing machine.Speed-wise, it doesn't seem to be particularly quicker than using a software RAID system like SoftRAID. My files copied at around 7GB per minute, which is what I'd expect from a JBOD caddy – but the Mac Mini to which this is attached seems much more spritely with this Hardware RAID attached than it did running a software RAID. So, overall, I'm very happy with the purchase.
5.0 out of 5 stars Useless. Totally useless
I bought this to extend an existing QNAP NAS and I wish I'd never bothered.It's possible to get it to interact with the NAS after endless tinkering but as soon as you restart the NAS, it's almost impossible to get this to reconnect.Eventually after rebooting both devices in different orders, one might be lucky enough for the RAID to reconnect, but it takes far, far longer than it should.Additionally, you can't extent the device once you install it. I bought this with 2 drives, planning to add 2 more later. Doesn't work.This is the single worst tech device I've ever bought.
1.0 out of 5 stars Frustrating! And a disappointing feature set. Not as good as a purpose-built OEM external drive
I bought the QNAP TR-002 to house a couple of Seagate Enterprise drives for use as direct attached storage (DAS) for archiving purposes. Set-up was immensely frustrating, and the unit has only basic functionality as a DAS, with some disappointing drawbacks compared to using a purpose-built OEM external drive unit inclusive of hard drives (the latter would of course have cost more overall, hence my decision to try this QNAP device).Build quality is just about okay. It's all plastic, and the drive trays are VERY plasticky, feeling far too cheap and brittle, and seemingly insufficient to be able to carry the weight of a 3.5 inch hard drive without breaking in half. But, when the drives are installed, they provide some stability themselves. The drives clip in to the carriers (the clips are frighteningly brittle plastic and seem likely to snap in half as the unit ages) and don't necessarily require screws if the device is being installed and left where it is. Nevertheless, screws are provided and recommended for additional stability if the drive is being transported.But trying to get the TR-002 up and running was where the fun really started. It was painful, and I was initially so frustrated with its refusal to operate as it should that I had it all packed up and ready for return. But after having already purchased the two hard drives, I eventually relented and decided to persevere.The first problem was just getting it connected to a Mac. After installing the drives and software utility, plugging the unit in, connecting it to the Mac and switching it on, all that happened was that the drives would spin up, the blue USB light would come on briefly to indicate an active USB connection, but then the light would go out straight away and the drives would spin down, and that was that. Deadly silence. The drives would simply not mount. Neither Disk Utility nor the QNAP External RAID Manager software could help. The user guide is brief and gives no troubleshooting information that is of any relevance under such circumstances.After some considerable time, I eventually solved the connection issue by trial and error, although I'm still not sure precisely what made a difference. I tried different combinations of disconnecting the power, removing and reinstalling the drives, pressing the 'Set' button on the back of the unit, and swapping USB cables and ports on the Mac. After an hour of despair, a similar thing initially happened as before, i.e. the drives would spin up and then down again and the USB indicator would come on briefly and then go out, but this time the drives immediately began spinning up for a second time as the unit appeared to be trying desperately to leap back into life and connect to the Mac. After about 15 seconds of rumbling away, the drives appeared on the desktop and all appeared to be working. I have no idea precisely what eventually resolved this issue.The default factory configuration (set via three tiny, old hat dip switches on the back panel) is set to 'Software Control' and the unit came with the RAID mode configured to 'Individual' (i.e. two independent drives). The 'Software Control' setting enables you to change the RAID mode using software rather than fiddling around with the dip switches themselves (these also allow you to set the RAID mode without using the software). RAID options for the TR-002 are RAID 0, RAID 1, JBOD and 'Individual', where the latter makes each drive available as two completely independent external drives.I ran a soak test copying some heavy-duty files onto each drive with no problems.But I then installed a fully bootable macOS onto one of the drives to test it as a boot volume. This was another disappointment, as the TR-002 does not support booting from a macOS volume, seemingly because it can't establish a stable USB connection until long after the Mac has booted. This is not the case with a G-Tech external USB enclosure which supports booting via USB without problems.So I then decided to try the RAID 1 setting, one of the main reasons for choosing this device. But this, again, was no fun at all. Using the software to reconfigure the unit appeared to work initially, but when the unit restarted I was right back to the beginning, with the TR-002 completely failing to spin up and connect to the Mac. After another hour of wasted time trying to troubleshoot this same situation I eventually somehow managed to force a connection to the Mac once again. As expected, it then told me the drives required initialisation. So off to Disk Utility to format the drive(s)...More problems. Initialising the drives failed repeatedly, with Disk Utility reporting an error message saying the drives were corrupted. So I was back to more troubleshooting, connecting, disconnecting, powering down, removing and swapping drives, restarting etc. etc. and again, the unit eventually restarted and requested once more that the drives be initialised. This time, initialisation was a success.At long last, we were in RAID 1 mode, so again I ran a soak test copying some heavy-duty files and had no problems.But then I tried to partition the logical drive so that it appeared as several smaller logical drives on the desktop. This was a repeated failure, with Disk Utility reporting a drive error every time. So I contacted QNAP who responded in a couple of days, only to confirm that: "you are not able to create multiple partitions with this expansion bay." Well that was another disappointment. Again, my trusty old 'G-SAFE' RAID 1 enclosure has no issues in this regard.But then, after having tried unsuccessfully to partition the logical drive, it once again became totally unusable, with Disk Utility now unable to erase and reformat the drive as a single partition without reporting drive errors. So I appeared to be stuck yet again, and it was back to the troubleshooting. After jumping through all the hoops listed previously, I was eventually able to restart the TR-002 and successfully reformat the drives.But then I made the mistake of seeing how effective changing the dip switch settings on the back of the unit might be, compared to using the software to configure the unit. Despite following the user guide precisely, making changes to the dip switches resulted in complete chaos once again, with the drive becoming inoperable as on previous occasions. So lots more powering down, disconnecting, changing ports, swapping drives, etc. was required once more, and after another hour or so of trial and error, I managed to get the system working, having eventually been able to use the dip switches to change from RAID 1 back to 'Individual' mode. What a palava this thing is.I then attempted to partition the individual drives, assuming that, as it's no longer operating in a strict RAID mode, this shouldn't be a problem. But, you guessed it, more 'corrupted drive' messages from Disk Utility which failed miserably to partition even a single independent drive. After yet more time troubleshooting as before and an eventually successful restart, I was ultimately able to partition the individual drives without further ado.CONCLUSIONSAfter endless testing, I found this device to be insanely frustrating with regard to the initial set-up and any subsequent change of RAID mode, all of which took endless hours of troubleshooting to eventually get the thing to work properly in any selected mode. And all of which remains inexplicable, except to say that this device clearly does not like being switched from one mode to another, something that should be seamless but which instead creates total chaos.However, as and when you eventually get the thing working, it appears to be stable and reasonably quiet, copying data as expected without issues, at least for now.But other disappointments include no support for partitioning the logical drive when in RAID 1 mode.And it does not support booting from a bootable macOS drive or partition, so it cannot be used as an emergency start-up drive.None of the above instils great confidence with regard to long-term dependability or the safe keeping of valuable data. And it's not a substitute for a reliable data back-up option.Having said that, I'd already bought the hard drives, so I have resigned myself for the time being to continuing to use the TR-002 to provide some additional studio redundancy as a dual (two individual drives) drive enclosure for day-to-day archiving, but am going back to G-Technology (now a Western Digital 'Sandisk' branded product) for their superior, proven, more fully-featured, and more easily installed and configured RAID systems.Based on my experience, I would not recommend the QNAP TR-002 as a RAID enclosure. Although I was eventually able to get the device working, this was not without endless hours of trial and error. And the inexplicable refusal of the TR-002 to just do as it was told was immensely frustrating. With all that in mind, I'd say that this is quite simply the worst ever external DAS unit I have experienced in 30 years of using and configuring Mac systems and peripherals.Would I buy another? Nope, sorry QNAP.It's cheap and cheerful, and you get what you pay for. I'd rather pay more and have an easy life!
Easy set up.

Atendeu, até agora, minhas expectativas
Apos uma semana deu defeito: só acende a luz verde no "status". Não lê o HD nem se comunica com o meu notebook.Apos analise cuidadosa, verifiquei que problema apresentado foi no Cabo USP. Corrigido, o aparelho voltou a funcionar e atende perfeitamente minha necessidade.
Semplice da configurare, affidabile e con ampio spazio di archiviazione
The media could not be loaded. Ho acquistato questo DAS della QNAP e l’ho dotato di 4 dischi da 6 TB ciascuno, specifici per NAS. Ho optato per una configurazione RAID 1, ottenendo così una capacità di 18 TB effettivi, con la sicurezza di poter recuperare i dati anche in caso di guasto di un disco.La configurazione è stata sorprendentemente semplice: l’interfaccia utente è intuitiva e, anche senza essere un esperto, sono riuscito a impostare il tutto in pochi passaggi. La guida fornita è chiara e i vari strumenti di monitoraggio permettono di tenere tutto sotto controllo in tempo reale.In uso, il DAS si è dimostrato silenzioso e performante, ideale sia per l’archiviazione di grandi quantità di dati che per l’accesso rapido a file pesanti. Inoltre, il fatto che sia progettato per funzionare senza problemi con dischi ottimizzati per NAS mi ha dato ulteriore fiducia nella sua affidabilità a lungo termine.In conclusione, sono pienamente soddisfatto del risultato e del prodotto. Consiglio vivamente questo DAS a chi cerca una soluzione affidabile e facile da configurare per le proprie esigenze di archiviazione dati.
Eine solide Erweiterung für meinen Speicherbedarf
Das QNAP TR-002 hat meine Erwartungen als Speichererweiterung voll erfüllt. Als jemand, der viel Wert auf Datensicherheit und Geschwindigkeit legt, war ich auf der Suche nach einer zuverlässigen Lösung.Was mir besonders gefällt:Flexibilität durch RAID: Die Möglichkeit, verschiedene RAID-Konfigurationen einzurichten, gibt mir die Sicherheit, dass meine Daten auch bei einem Festplattenausfall geschützt sind.Schnelle Übertragungsraten: Dank USB 3.1 sind die Datenübertragungsraten hoch. Ich habe das Erweiterungsgehäuse an mein bestehendes NAS angeschlossen.Kompaktes Design: Das Gehäuse ist kompakt und passt problemlos in den Schrank zum eigentlichen NAS..Einfache Einrichtung: Die Installation und Einrichtung waren dank der mitgelieferten Software unkompliziert. Lediglich das mitgelieferte USB Kabel könnte länger sein.Was man beachten sollte:Lüftergeräusche: Unter Volllast ist der Lüfter hörbar, aber nicht störend laut.Preis: Das Gerät ist in der höheren Preisklasse angesiedelt, aber die Qualität rechtfertigt meiner Meinung nach den Preis.Das QNAP TR-002 ist eine solide Wahl für alle, die ihre Speicherkapazität erweitern möchten und Wert auf Geschwindigkeit und Datensicherheit legen. Die einfache Bedienung und die flexible Konfiguration machen es zu einem zuverlässigen Begleiter im Arbeitsalltag.
Super Festplatten Erweiterung
Ich nutze das Gerät als Raid 5 mit 4 Festplatten. Ich hatte es testweise am Windows PC und über die QNAP Software konnte man alles gut konfigurieren bzw. sich einen guten Überblick verschaffen.Derzeit nutze ich das Gerät als NAS Speicher für einen Odroid (Raspberry Pi äquivalent). In Linux wird das Gerät ebenso gut erkannt und läuft ohne Probleme. Von der Lautstärke her ist es in Ordnung aber im Wohnzimmer würde ich es nicht unbedingt direkt stellen, evtl. in eine hintere Ecke oder etwas versteckt im Schrank oder ähnliches.Feedback zum QNAP Support, inkl. Fehlerkonstellation:Bei meinem alten (eher noname) Festplattenerweiterungsgehäuse war die Leiterplatte schlecht verlötet und beschädigte 2x NAS Festplatten nach 1 Jahr. Weshalb ich das Gerät gegen ein etwas hochwertigeres tauschen wollte --> von QNAP. Glücklicherweise war die 2 jährige Gewährleistung in beiden Fällen noch nicht abgelaufen, so dass keine Zusatzkosten entstanden sind.Der QNAP Support war mir in diesem Fall auch eine Hilfe und es ist lobenswert zu erwähnen, dass dieser mir nach längerem hin und her zur Fehlersuche einen kostenlosen Austausch/Rückgabe angeboten hat. Was aber über Bolo sowieso kein Problem gewesen wäre. Jedenfalls konnte ich durch den Support den Fehler auf die 2 beschädigten Festplatten eingrenzen, da ich zuvor nicht zu 100% sicher war ob es wirklich an den Festplatten lag. Daher gibt es auch für den QNAP Support eine 1+.
