The RAID1 functions as expected.
I purchased the D2-320 2-bay RAID enclosure with USB 3.2 Gen 2 10 GbpsMy purpose with this unit was to mirror (RAID1) two 6TB WD Reds with a Linux machine. Iâm not familiar with this brand, so I decided to test it a little before copying a lot of my files over to the D2-320.Getting everything working was pretty easy.I pulled out each bay, installing the drive was pretty easy, no screws needed. They provide a video on it if youâre unsure. I set the selector on the back of the unit to RAID1, shoved in both drives, connected the USB (drives are powered but wonât spin up until the USB is connected), then held the RESET button with the provided pin until the disk lights flashed. The system found one drive – as it should have.I wrote approximately 18K files and directories of various sizes to the array and then without disconnecting the USB or turning off the power, I pulled out one drive. I then connect the pulled drive directly to another computer to see that the files were in fact written to the drive. They were. All good to go.I replaced the drive. Both lights are green. Since no changes had been made to either drive, this is perfect, it didnât try to rebuilt the arrayNext, I pulled the second drive out hot. Then connected that drive to the other computer and checked to make sure all files were also written to this drive as well. They were! It is working as it should be.I then created a couple files on the other drive and then replaced the pulled drive back into the D2-320. One drive light was blinking green, the other blinking yellow. According to the online documentation, this means it is rebuilding the RAID1 mirror. Perfect .. Everything is performing as expected. It did take a few hours to rebuild .. but these are 6TB drives, so that was expected.The USB cable provided seems adequate, USB C on both ends. If you need a different cable, consider that when purchasing.Average 1G file write 156 MB/s, average 1G read 221MB/s. Slow but these are mechanical drives connected via USB. Acceptable. Later, I watched a video using Jellyfin and reading, transcoding, and streaming worked perfectly fine.The large fan is quiet and seems to keep the drives cool. Airflow looks to be sufficient. How noisy the unit will be will depend on your drives. Some are louder than others.These drives will be part of a system I have in place which will be up and running 24/7. Iâll be very interested in seeing how well the Terramaster D2-320 performs in the long run. Iâll post updates after I have used them for some time.

Use with Plex Server
I purchased two of these to be used with a Plex server running on a Mac Mini, one for the main server and one for offsite backup. I populated both of them with WD RED NAS drives and everything is working great. I am getting around 200 mb/s per second on each drive. Considering the WD website says that the drives are rated at 180 mb/s, these speeds are better than I had hoped.It was extremely easy to setup as well and the Mac recognized the device without any drivers needed. I popped in the first hard drive and named/formatted. Once done I did the next. I did this for all four drives. I just popped in the next drive while the device was still on. I did this so that the drive names on the main server and backup would not only be the same, but in the same spot in the device. I am not sure how you would know which drive was in which slot if you simply threw all the drives in and plugged it in. This approach would be fine for most people, but I need the backup setup the same as the main so I can swap drives when necessary.My experience so far has been great. Drives showed up instantly, no issues with naming/formatting, speeds are where they should be, and no fussing with drivers/software. The drives also seem to sleep while not in use, which I like from a power saving perspective. This is a 24/7 server and having the drives go to sleep is an added benefit if they are not in use. I have had no issues with them waking up as soon as needed.The device is mostly silent. You can hear a slight noise when the fans kick on, but no complaints on the sound. The build quality is nice as the device is made of metal, except that the trays that hold the drives are plastic. Would have been nice if these were metal, but if pushed in properly they should hold up fine. The box also came with stickers for labeling the drives and additional feet in case they come off. This isn’t a big deal, but I found it to be an extra nicety.

Es una aliviané para editar video y audio con los NVMA, transferencia rápida y suficiente, si necesitas más rapidez este no es para ti. Tiene 10gps de velocidad por el USB C- los discos normales para backup son un aliviane.

Non solo è praticissimo per chi deve avere a che fare con tanti HD, “swapping” veloce, USB C e tutto il resto, comodo da morire. Ho pure scoperto che la ditta ha un’assistenza post vendita letteralmente stellare. Avevo bisogno di sapere come comportarmi con il voltaggio differente in USA (120V 60Hz) avendolo comprato in Italia (230V 50Hz) così gli ho scritto una mail con la questione e questi mi hanno mandato alla chetichella e senza neanche fiatare un altro alimentatore con la spina USA, pazzesco ! Soprattutto considerando che A) sarebbe bastato solo il pezzo di spina USA (l’alimentatore si adatta da solo ma l’ho scoperto dopo) e B) il costo dell’intero maccherone è di ben 40.00 USD. Non hanno domandato o voluto un centesimo. Ho visto che ne hanno una versione update, appena posso ne compro un’altro, sono veramente soldi ben spesi.

Habe lange überlegt welches TerraMaster Festplattengehäuse ich mit zulege. (dieses hier oder eines der 5-Bay mit RAID). Die Recherche war nicht ganz leicht, da sowohl hier als auch auf der Herstellerwebsite durchaus unterschiedliche Informationen zu finden sind.Der TerraMaster Support über Live-Chat war allerdings sehr kompetent und hilfreich und hat offene Fragen innerhalb von wenigen Minuten klären können.Jetzt zum Produkt:Das Festplattengehäuse hat ein massives Metallgehäuse (Alu?) und sieht sehr wertig aus. Auch die Verarbeitung ist sehr gut. Die Festplatteneinschübe selbst sind aus Kunststoff, was aber völlig ausreichend erscheint. Sie passen perfekt, nichts wackelt oder klappert.Das montieren von 3,5 Zoll HDD’s als auch 2,5 Zoll SSD’s auf den Einschüben geht problemlos mit jeweils 3 Schrauben. Sicherlich sind die Einschübe nicht zum täglichen Wechseln ausgelegt, dann hätten sie wohl aus Metall sein müssen, aber wer macht das denn bei Consumer-Hardware schon?Der Lüfter ist überraschend leise und durch die weichen GummifüÃe werden auch keine Vibrationen übertragen. Selbst auf dem Schreibtisch direkt neben dem PC sind die Geräusche kaum wahrnehmbar.Aktuell steht das Gerät in einem Schrank mit Lüftungsöffnungen. Nachts (bei völliger Stille) ist ein ganz leises Rauschen wahrnehmbar. Dies ist aber leiser als jede Klimaanlage oder Kühlschrank.Sowohl der Stecker den Netzteils als auch der USB-C Stecker des mitgelieferten Kabels passen gut und sitzen sehr fest, was ein versehentliches herausziehen praktisch unmöglich macht.Zu meinem Setup:Ich betreibe die TerraMaster D4-300 an einem Proxmox-Server als Datenspeicher und für tägliche Backups. Deswegen habe ich mich gegen die anderen TerraMaster Variaten mit RAID entschieden, da ich das für meinen Zweck nicht brauche. Die Möglichkeit jede Platte einzeln anzusprechen ist genau das wonach ich gesucht habe.Ich betreibe in den 4 Slots 2 SSD’s und 2 groÃe HDD’s im Mischbetrieb. Das ist ohne Probleme möglich.Das Temperaturmanagement des Gehäuses ist erstaunlich gut. Auch bei den nächtlichen Backups, wo alle 4 Platten unter Last laufen, steigt die Temperatur der einzelnen HDD’s und SSD’s nicht über 38 Grad. Das Gehäuse wird maximal handwarm (im geschlossenen Schrank), bei geöffneter Tür nicht wärmer als Zimmertemperatur.Der Stromverbrauch liegt im Idle so grob bei 10-15 Watt, was ich für ganz okay halte.(Habe aber keine Einzelmessung der TerraMaster, nur des Gesamtsystems)Fazit:Wer einfach eine bezahlbare Speicherlösung sucht und kein teures NAS braucht, ist mit den Festplattengehäusen von TerraMaster auf der sicheren Seite.
