L'utilizzo è prevalentemente come libreria di file video, originali ed ottimizzati, da lavorare con FCPX, e come memoria virtuale per Photoshop.
La scelta è ricaduta su questo case dopo averne provato uno di un'altra marca che, però, aveva problemi di disconnessione "spontanea" dal computer e che ho dovuto restituire.
Ho "beccato" una delle offerte periodiche a 135 Euro, cifra che, secondo me, rappresenta l'ottimale rapporto qualità/prezzo di questo oggetto.
La spedizione è stata rapidissima; il case arriva, ben protetto, in una scatola contenente il case stesso, un cavetto USB-Type C > USB 3.0 della lunghezza di circa un metro, due sacchettini di viti per l'installazione degli HDD (un sacchettino per gli HDD 3.5" ed uno per gli HDD o gli SSD da 2.5"), due cacciaviti (uno grande a croce ed uno piccolo a taglio, per ruotare lo switch), un alimentatore con adattatore per presa Europea e inglese, una scheda con diverse FAQ, un set di etichette per catalogare gli HDD ed uno strumentino, del tutto simile a quello per le schede SIM dei telefoni Apple, utile per premere il tasto "reset" e cambiare modalità RAID.
L'aspetto esteriore restituisce una sensazione di qualità elevata: è quasi tutto alluminio, con finitura satinata molto compatibile con l'estetica dei computer Mac.
Sulla parte frontale sono presenti un pulsante di accensione e spegnimento, con relativo LED, i due LED per gli HDD interni che segnalano la presenza (LED fisso) ed il funzionamento (LED lampeggiante) dei drives ed i due contenitori scorrevoli per gli HDD.
Nella parte posteriore è presente una ventola termocontrollata, molto silenziosa, uno switch rotante a 4 posizioni per selezionare la modalità scelta tra le 4 disponibili (RAID 0, RAID 1, JBOD o normale), il tasto di reset, una presa USB 3.1 Gen. 2 (Type C) e la presa di alimentazione.
Appena inseriti gli HDD, nel mio caso due Seagate Barracuda da 3TB l'uno, questi vengono immediatamente individuati ma è necessaria l'inizializzazione perchè vengano visti come HDD atttivi dal Mac.
L'inizializzazione dura una manciata di secondi.
Personalmente, ho preferito sostituire il cavo USB originale con un cavo che avesse connettori Type-C su entrambi i lati, per essere certo di sfruttare al 100% la velocità consentita da questa connessione.
Ho quindi testato i dischi in funzionamento singolo, con BlackMagic Disc Speed Test, ed i risultati sono stati ottimi ma stranamente diversi tra loro: dopo numerose prove, uno dei due dischi ha semrpre raggiunto le velocità tipiche indicate dal produttore (185-190MB/Sec), mentre l'altro ha raggiunto i 210-215MB/Sec, sia in lettura che in scrittura.
In ogni caso, il case non rallenta in alcun modo la velocità dei dischi inseriti al suo interno.
Con gli HDD inizializzati e con il case acceso, si seleziona poi la modalità scelta tra le 4 disponibili, si preme per almeno 5 secondi il tasto reset ed il gioco è fatto.
A questo punto, nel caso si scelga una modalità RAID o JBOD, il Mac richiederà una nuova inizializzazione dell'unità.
Dopo aver terminato la seconda inizializzazione dell'unità in RAID 0 (6TB totali), ho nuovamente effettuato dei test di velocità, sempre con BlackMagic Disc Speed Test, ed il risultato è stato di 355-365MB/Sec in scrittura-lettura, davvero notevole!
Ho quindi riversato sul disco oltre 2TB di foto, video e dati vari, ma non è indicativo riportare il tempo impiegato per tale operazione, in quanto la velocità di scrittura del case è stata limitata da quella di lettura del disco interno del Mac.
La temperatura del case, dopo un paio d'ore di funzionamento in scrittura continua, non era variata minimamente, il case non era nemmeno tiepido!
Ho poi effettuato numerosi test, accendendo e spegnendo il Mac, lasciandolo spento per diversi minuti con il case acceso, attivando e disattivando la modalità STOP, lasciando inattivo il tutto per molto tempo e l'unità è sempre stata vista dal Mac alla sua riaccensione, cosa che non succedeva con l'altro case.
Addirittura, dopo alcuni minuti di inutilizzo, i dischi si disattivano automaticamente, per poi riattivarsi immediatamente non appena si "chiedano" dati presenti sull'unità stessa o si riaccenda il Mac, ma non so se questa sia una caratteristica del case o degli stessi dischi!
Sono soddisfattissimo del mio acquisto anche se non posso fare a meno di notare l'inutile economia fatta da TerraMaster nel fornire un cavo USB 3.1 > USB 3.0 e non un cavo Type-C su entrambi i lati; io l'ho dovuto acquistare separatemente al costo di 16 Euro e, in un prodotto di questo livello, questa mancanza dovrebbe far meritare una stella in meno, ma questo oggetto è talmente perfetto, bello e veloce nel suo funzionamento che, personalmente, non me la sento di dare 4 stelle solo per questa ragione.
Un altro aspetto che potraebbe lasciare perplessi è costituito dalla necessità di assicurare i dischi ai propri supporti con le viti, contrariamente ad altri case che prevedono l'inserimento e l'estrazione rapida dei dischi, senza necessità di viti, ma questo è giustificato dal fatto che il case è compatibile con tutti i formati di drives, compatibilità non presente nei case con sistema ad estrazione rapida.
Anche l'assistenza, per ora e per quel poco che ho potuto testare, posso dire che è SUPERLATIVA: hanno sempre risposto in modo esauriente e rapido alle mie numerose domande.
Consiglio l'acquisto a chiunque sia alla ricerca di un case di ottima qualità, ad un buon prezzo (se non avete fretta, però, aspettate le periodiche offerte a tempo da 135 Euro!), assolutamente compatibile con iMac, sia esteticamente che nel funzionamento e dalle ottime prestazioni!
There may be reasons to have the two drives individually used for different types of files, possibly one for downloaded music and the other for books or movies and identified independently as Drives E and F under Windows; for this enclosure, that position is labelled as 'SINGLE' which differs from other brands' nomenclature who mostly choose JBOD (Just a Bunch of Drives) for it. The Final mode is actually marked as 'JBOD' which, for most brands is variously labelled as 'SPAN', 'BIG', 'LARGE' or 'COMBINE' and allows two drives of very different capacities to be used where their capacities are added together. For non-critical applications, and when capacity is king, JBOD (as is used here) may offer the best choice. A bright yellow label is attached to one side of the enclosure that clarifies its terminology.
Setting of a Mode cannot be much simpler as there is a single small rotary switch at the rear to select one but it will need a small-bladed screwdriver, and then to validate the mode by holding in the RESET button for up to 5 seconds until there are two sequential 'bongs' - a small pin tool is provided for the purpose but a straightened paperclip will also work. You will need to supply the drive units required (up to 12TB each) and format them as appropriate to the selected Mode, capacity and your computer's OS. The enclosure is powered after a quick press of the POWER button and turned off after holding it down for 3 seconds. The power LED and the two Status indicators are tiny and non-intrusive; the Status indicators will flash green while reading or writing, steady green when idle and red in the event of an error.
Data connection is via a provided USB-C to USB 3.0 Type-A 1m-long cable. In the event that the enclosure is not to be used immediately adjacent to the host PC, the lead may need to be substituted by a longer double-ended USB-C cable or a longer version of that supplied (2 and 3m lengths are possible) to suit the host; otherwise a USB 3.0 extension cable will work.
Personally, TerraMaster was not previously used as a brand although others are known who use and trust them (both with a larger 5-bay model). A single Taiwanese brand was previously used for several years, chosen for their extensive range of RAID enclosures to meet differing demands, but that is likely to end as recently introduced models were found to be dramatically less capable than claimed and lower than the older models they replace. One from each of two new series was separately purchased from different suppliers and found to be similarly limited; technical support from manufacturer and sellers is at best weak and non-committal, especially lacking by the manufacturer whose support should be expected to be reliable, but not needed until encountering the problem.
PS - While the original unit has worked perfectly with three different sets of hard drives, a second unit purchased 10/19 has not. It is very fussy about some drives and drive types (all proven to work perfectly in other RAID enclosures); some including a Toshiba NAS drive were never recognised.
Right from the outset it is clear that Terra-Master put a lot of thought into the construction of the unit, the included items, and the packaging.
The D2-310 is a two bay direct attached storage enclosure. You need to purchase the disks separately according to your requirements. It can be configured to present the two physical drives individually to the computer, Combine their capacity into one drive - Raid 0 (higher performance but lower reliability than the physical disks) or Mirrored - Raid 1 (Higher reliability as if either physical drive fails you can replace it while the other continues to provide service and preserve your data,).
Configuration of the enclosure is very simple and basically involves fitting the drives, selecting the mode of operation (Raid 1, Raid 0, or individual drives) on a small rotary switch, and pressing a recessed reset switch to activate the change. You then need to use the normal disk preparation utilities of your computer to prepare the new space. There is no specific software to accompany the drive - it isn’t required. Getting started instructions are included and prominent stickers on the unit itself provide guidance.
The construction of the unit is very solid. The main body is very solid aluminium. There front and rear panels are silver plastic (which unusually for silver plastic are very presentable). The front panel has indicator lights for the two drive, a power light and a on off button (the operation of which is very solid). The rear panel includes the USB-C connector, a DC input for the included external laptop power adapter, the rotary mode switch and the reset button. Also on the rear panel is the fan. The Fan is very quiet in operation. The drive caddies are also silver plastic. In contradiction to the feel of the rest of there unit, they feel a little flimsy when out of the enclosure but are well sufficient for the job. On closer inspection nice touches to the caddied include labelling of the individual caddies as HDD1 and HDD2 to ensure that if they are removed, you know the order in which to re-insert them. Additionally the caddies runners are sprung to ensure that they locate properly.
The performance of the unit is very good. There is no evidence that there is any additional cache storage on the unit or protection from drive corruption in the event of sudden power loss, but then again this is a basic enclosure.
As hinted above, I considered that Terra-Master put a lot of thought into the presentation of the unit. The package includes plenty of screws to mount various typed of hard disk This includes including the two screwdrivers that you need to provision the unit - one for the hard disk screws, and a tiny one to adjust the mode switch. In addition there is a proper tool to press the recessed reset switch (similar to a mobile phone sim eject tool - no need to unfold a paper clip!). The included USB cable is USB-C (enclosure end) to USB A (computer end) If your computer has a USB-C connector then you will need to buy an additional cable (I bought an Amazon basics USB-C to USB-C cable which seems OK)
Should it be necessary to replace a failed hard drive when using RAID 1 (mirrored drives), the unit will automatically rebuild your data onto the new drive, however it is important to leave the enclosure powered up AND the attached computer (also powered up) until the build is complete. That is a little unusual, but hopefully you will not need to do that very often.
It is worth consulting the list of recommended drives on the Terra-Master website before selecting drives. There is obviously a trade off between reliability, price, speed, and noise. I went for speed/reliability over cost/noise. Your priorities might be different.
All in all I’m very satisfied with the unit. Plus points - Solid construction/complete kit; Minus points - difficult to find any.
This Two-bay RAID sits alongside the 5 Bay TerraMaster Enclosure I purchased about a year ago and which has run flawlessly since.
I tried several makes of RAID Enclosures before TerraMaster but found most of them lacking in their temperature control/cooling functionality, some were very noisy in operation, and few allowed S.M.A.R.T software monitoring.
TerraMaster is excellent at all of these and I have no hesitation in recommending their products to all.
I hope you will all be as satisfied as I have been.
- This enclosure spin down the drives when they aren't used, it's insanely fast for a USB enclosure with spinning drives, and the cooling fan is almost silent.
- The fan does not turn off. Ever. Not even during sleep mode.
- If you shut down your computer, the drives are spun up, and will run continuously (with the fan on), until you turn it off manually. This is an annoyance, and could be solved via firmware.
I like performance, but I also like to prolong the life of my drives and enclosures. I have been in contact with the manufacturer, and they are presumably working on a firmware fix, so the enclosure can turn off the fans and sleep the drives after a few minutes with no contact to a host (computer). Will update my review when that happens.
I bought this to transplant the drives from a WD My Book Duo which employed enclosure based encryption, so I couldn’t read the drives individually outside of the proprietary enclosure. Initially, I had hoped to use the enclosure to present the two disks independently and use software raid in the Windows OS, but unfortunately this doesn’t seem to be possible. This is because they cannot be converted to dynamic disks over the USB interface. Storage spaces wasn’t happy to use the disks independently either. Instead I was forced to use the drives ASMedia Raid chipset to create a mirrored pair. I tested the resulting RAID1 set by filling it with data and then removing one of the drives. This removed drive was inserted into a USB->SATA dock and when connected I could see all of the data was there and accessible. I have confidence that should the enclosure die, I can still access the files from the drives (unlike the WD Duo). For completeness, I used diskpart to wipe the drive and its signatures and re-inserted it into the Terramster (while powered off) and once powered on, the RAID1 set rebuilt itself automatically without issues.
Unfortunately, the chipset used for this enclosure doesn't seem to support SMART over USB. It would have been nice to monitor the Hard Disk SMART data, especially to see the individual drive temperatures, but I guess you can't have it all for this price.
Compounding the lack of SMART monitoring, the 2-drive version of the enclosure doesn’t come with monitoring/configuration software either, so you can only find out the health of the drives when it's too late (i.e. broken).
This product could be improved though with an improvement (or total omission) of the supplied screwdrivers. They are so poor quality that the chrome plating on the tips of them chip off and fall around whatever screws you're tightening - most likely the hard drive screws around the PCB of your expensive drives. Mine did this on the first screw so I immediately discarded them as they were a liability.
A longer USB3 -> USB-C cable would have been nice too.
Even with the shortcomings above, I'd still recommend this device.
The quick start paperwork directs you to very clear and easy to follow online instructions for formatting the drives and allocating a drive letter to the device.
Mine's been in use in RAID 1 configuration for a few weeks now as part of my storage and backup system for my photography business and has performed faultlessly. It also runs considerably quieter than the brace of - very good - Icy Dock drive enclosures that I have running nearby.
So for me it's a case of so far so good and if it stays that way for another few months I intend to buy another.
Comes with all the tools you need to get going.
You have to go to the website to get the user guide as to way its not working.
Once the drives are in you power it up and wait for the hard drives lights to go from amber to green - the don't.
You unplug and plug the USB 3.1 connector on your PC, you see that the box has detected this but still nothing happens. You press the reset button in for 6secs and release causing it to rebuild the Raid1 (I wanted security not speed). Still nothing. Then moving the box the usb-c connector made a better connection (it was pushed home before but the angle was wrong) then when I ran DISKMANager I could see the new disk, which I then formatted.
This is meant to be a 'FAST' 5Gbps usb3.1 connection. I am copying from my M.2 drive to this and the files (css/gifs) are slowly moving across. So you have to wonder why use a USB-C version when it would have been more reliable with a USB3 connector. However, if you are using it with a laptop or an ipad then it makes sense.
The supplied connector has the best of both worlds with the new reversible type C connector at the drive end and the USB3 and USB2 backward compatible USB3 type A connector at what will be your computer end. I already have a type C to type C lead so stepped up to the USB 3.1 transfer speed right away.
In no time at all I had my 5 TB media files copied over and the unit out on long term lease. In use the enclosure is every quiet and runs cool. Comes with a nice high amperage heavy duty AC to DC convertor as well with the correct mains plug fitted as well, which is a real plus for UK owners. Tom Waller International Music Services (Malta)
STOP Press, just purchased and received a 2nd unit which is already in service in a Busy seaside Bar popular with locals and tourists alike.
The construction is very good with a solid metal case and rugged, locking plastic caddies. The front has the two disk holders, the on/off switch, power LED and two disk activity LEDs. The back has the USB3,1 connector and power input socket and a RAID selector dial and reset button. So a simple, clean design.
Fitting the disks is as easy as inserting four screws and pushing the caddies into the case. Switch it on, select the RAID format and press the reset button, do the normal new disk installation stuff on your computer and away you go.
Transfer speeds seem very good.
I'll be buying more of these
