5.0 out of 5 stars Easy expansion
Fast and easy expansion for a QNAP NAS or a computer. Easy to fit HDD.
5.0 out of 5 stars Ok but quite slow writing as is to be expected
I filled the device with four 10TB WD Red Pro NAS drives that already had data on them.As a test, I set it to individual drive mode and Windows detected all the drives and assigned a letter for each one. This is exactly what you would expect.Next, I switched to software controlled mode and installed the software. I reconfigured the drives as one large RAID 5 array. It built the array quite quicky and Windows detected it as one large drive. Again, exactly what you would expect.I haven't connected it to my NAS because it wasn't purchased for that purpose so I can't comment on that aspect of the device.It wouldn't win any awards in the speed department but overall, I'm quite pleased with it for the price I paid.One point I feel I should make about QNAP NAS, DAS and JBOD enclosures is that the caddies really need the screws fitted as the clip in disk retaining strips don't support the drives well enough on their own. Personally, I feel that the instructions should tell the user to fit them rather than stating that fitting them is optional.Another thing is that if you have to replace a drive and rebuild the array, it doesn't start until the host is alive and is best to set the host not to sleep because if it does, it will interrupt the rebuild and can cause loss of all the data.
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 a little fiddly but works as advertised
cheap and plasticy but does what it says it does
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.
Easy to set up,no problems so far.
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.
Funciona tal como anunciado. Bom design visual.
The media could not be loaded. Bastante fácil de instalar. É só puxar as alavanças para destrancar os "tabuleiros" dos HDD a inserir (certificar que as portas não estão trancadas: Isto é um ponto importante porque as "fechaduras" destas portas em plástico mais a chave também em plástico são o único ponto fraco que encontrei neste aparelho. É preciso ter boa luz apontada ao trinco para ver se estão trancadas ou não. A forma de ver isto é a marcazinha na fechadura que aponta ou para o cadeado fechado (a porta encontra-se trancada) ou para o cadeado aberto (a porta encontra-se destrancada). Mesmo a porta estando destrancada, é preciso "forçar" um bocadinho para ela abrir (metendo um dedo naquele espaço por baixo e puxando suavemente para fora). Uma vez que a porta cede, é só puxar que o tabuleiro sai completamente. Se os discos forem HDD de 3.5", não é preciso ferramentas. É só puxar (suavemente) as 2 peças de plástico em cada lado do tabuleiro, montar o disco e voltar a colocar essas 2 peças, e depois gentilmente inserir o tabuleiro com o disco. E assim por aí fora. Depois dos discos estarem lá, é recomendável trancar as portas, ajustar os pins RAID na traseira na configuração desejada (As configurações possíveis estão todas no manual) e depois ligar os cabos todos, ligar o aparelho, e carregar continuamente no botão "reset" até se ouvir um apito. Uma vez feito isto, é preciso esperar um ou até mais minutos até ambos os discos serem reconhecidos pelo aparelho. Um será reconhecido primeiro que o outro. Depois, caso use o Windows, é só ir ao Disk Management, e iniciar o disco, criar partição e pronto - Tem um sistema RAID pronto a usar. O cabo fornecido é USB-C na parte que liga ao QNAP e USB-A na parte que liga ao PC. é USB.3.0. O aparelho vem com mais algumas peças (como por exemplo parafusos extra) cuja instalação para HDDs é opcional. Eu escolhi não aparafusar estes parafusos pois os discos ficam completamente seguros sem os parafusos. Em suma, estou completamente satisfeito com o aparelho até agora, lembrando que acabou de ser instalado, mas já testei e fiz cópias de ficheiros e está a funcionar perfeitamente. É importante salientar que, sempre que se quiser mudar o modo de RAID que está a ser usado, todos os dados nos discos serão apagados para criar o novo RAID (esta informação está no manual também).
Hur få upp hårddisk kassetterna vid installationen?
Hade några hårddiskar över efter tidigare slaktade datorer. Bestämde mig för denna Qnap som ligger 1:a på prisjakt. Snabb leverans från Bolo. Installationen gick smärtfritt och hyggligt snabbt bortsett från att de tomma hårddisk kassetterna inte gick att få loss. Försökte låsa upp dem men det gick inte. Fick använda lite våld. Till följd att ett par av låsen demolerades. Fabriksinställningen var tydligen låst från början. Lite obegripligt. Om QNAP läser det här så får ni gärna skicka ett par kassetter till mig så kan jag byta. Förmodar att Bolo kan ge adressen. Bortsett från inledande strul så fungerar allt som tänkt. Installationen kördes först via datorn och raid 5 som inställning för att sedan kopplas mot min NAS-enhet (Synology). Använder den som backup.
Très bon boîtier
Très bon boitier pour disque dur, installation facile sans vis (pour disques 3.5 pouces). Détecté immédiatement par mon serveur sous Linux, de manière automatique. Ventilateur silencieux, chauffe maîtrisée.Niveau débit, à travers mon Wi-Fi (et serveur connecté en Ethernet) je télécharge un fichier à un débit d'environ 50-60 Mo/s (c'est le max possible en Wi-Fi 5).Il est compatible avec la technologie SMART pour suivre la santé des disques durs, ce qui est un bon point (sous Linux via le logiciel Smartmontools et le mode "sat").
