TERRAMASTER D6-320 External Hard Drive Enclosure - USB 3.2 Gen2 10Gbps Type-C HDD Storage Hot Swappable Plug and Play (Diskless)

The TERRAMASTER D2-320 is an excellent value. The slide in disk trays are easy to use, and dampen noise from the disks. I'm using mine in RAID0 (striped) mode for speed. I installed a couple of my oldest NAS drives, 1 TB Samsung, into the enclosure and plugged it into my desktop Windows 11 machine. Using it as fast scratch disk while re-organizing my photographs. It works great. It'd be nice if the disk trays could be locked in, but that is not a deal breaker. I'm happy with how quiet and fast the enclosure is.

Exactly what I needed... yes, it's shaped like a NAS.... but it's 1/2 the price while having the same design, I assume. This was replacing an external drive dock that I had which didn't reduce the noise of the two white label disks I had in them. This one doesn't make it fully soundproof but it is noticeably quieter... to the point where it doesn't make a loud annoying beep... but just turns on. No USB-3 B connector... a USB-C cable.... Performance is very good and while it's not 100% quiet, it's far better than the cheap unknown brand I had before. It fits and looks nice on a shelf.... and by default, the unit comes in Single configuration which has each disk as an independent disk... no RAID or JBOD (one logical disk with two disks....) In "single" mode, it worked how I wanted it with two separate mounts to where I could easily swap out 3.5" disks as needed (which I hopefully won't need)... but nice to have the option. So it's basically like a NAS that I would have bought but it's hooked into my Mac Mini M4 which is a far better NAS interface for what I want to do with it.

D2-320 arrived and looked good. solid construction high quality cables, parts fit well together. Installation is intuitive. So simple, in fact, I had it installed with 2 SSDs, THEN looked at the installation instructions. Transfer speeds are pretty good. USB 3.2 is a speedy boy, even with both drives hammering large (700G) transfers at the same tiime. Now, the issues. It has an EXTREMELY small supported product list. Trust me if your device isnt on the compatiibility list, its probably not going to work well. Support, while available pretty much 24 x 7, are extremely slow to respond in live chat...and in fact one of them went for an hour meeting while in chat with me without saying so. Support attitude is poor, at best. In regards to knowledge, they didnt tell me anything of value other than obvious things like "change what bays the drive is in"... well duh...rocket science. They even said that "Sharing" a drive via standard windows file sharing required a NAS rather than a DAS. sorry...wrong... Despite their fumbling support and extremely restrictive compatibiility list, I AM still using the product, and its functioning pretty much as good as it looks (which is pretty boring, but thats a good thing with computer hardware. boring means its working). I managed to sort out the issues myself, which werent really attributable directly to the product other than it not supporting faster, newer SSDs, and very few of the older generation drives. Would I recommend it? Probably not. Spend a little more. Update - New Samsung 870 EVO 1Tb drives arrives. Inserted into the DAS which proceeded to not see them. Windows Disk Manager did, however see them both and proceeded with addiing them and letting me format them. The DAS automatically detected the drives once they were partitioned and formatted. Setup Windows shares and they work perfectly across the network to another Win 11 machine and a Win 10 machine. Care must be taken on shares if you are hot swapping disks since it seems to be the slot in the DAS uniit that gets the share name and permissions rather than the actual disk. This is NOT the fault of the D2-320 but a windows thiing. Rating increased from 2 to 4 stars.

Wow, what an incredible alternative to expensive NAS setups. This thing is incredible. Speeds are great and it’s awesome that you can swap out drives in seconds with no hardware. It’s super easy, works great, and the indicator lights on the front are helpful. Stays pretty cool as well. I could see this being very useful for people who need a lot of storage, especially video editors. Honestly might hook it up to my router for cloud storage if I feel like a NAS is necessary without having to buy something more expensive. Save your money, buy this and spend it on hard drives.

This is a really great drive enclosure for three reasons: design, reliability, and value. I really appreciated the tool-less design. I fully loaded the enclosure with 4 drives in probably less time then it would take to screw mounting plates onto a single drive for other enclosures or a PC case. This also means that drive replacements in the future will also be quick. Not as important, but the general appearance is also very nice--a very clean design. I have owned several external USB drive enclosures in single and dual bay capacities in the past, but most of them were not reliable. In the middle of long transfers, the USB connection would always drop and I would give up entirely. This led me to think that USB was too unreliable for large data transfers and external hard drives in general. I am currently using this drive enclosure for storing large data backups, merged with DrivePool with parity by snapraid. The size of an individual backup can exceed 3 TB and this enclosure has not failed me yet. The connection is reliable. Multiple drive bay enclosures can get quite expensive. That this one goes for less than the price of a large capacity NAS hard drive makes it very affordable and a good value. Would definitely buy again and would consider other drive enclosures from Terramaster in the future.

I'd been waiting for this DAS to appear on Amazon since it was announced in March. I have a plex server with a number of 2.5" USB SSD drives dangling in the wind. This DAS helped keep me consolidate everything and organized my rack. Moreover, the server was already acting as a NAS for my larger network so this was a no-brainer for my use case. The USB 3.1 connection is very speedy with my SSDs. I'm impressed. Installation of 3.5" hard drives is tool-less and easy. 2.5" drives require some screws for mounting and quite a few of them come with this DAS. It looks like all of the SMART data (or the ones that I care about) of the hard drives are passed through to the host computer. The unboxing of the DAS was straightforward and simple. It came with 2 USB cables (C-C and A-C) and a power adapter. The fans are a bit loud, but it's racked in my basement so no one hears it. The DAS should have come with some cage nuts/screws but fortunately I had a few kicking around. Was it worth the price? For me it was, but just barely so - it helped me utilize some old 14TB 3.5" drives that I had laying around while keeping some of my larger SSDs. I may buy another one as my storage requirements increase, or perhaps consider a dedicated Terramaster NAS in which I could also utilize this DAS.

En la mayoría de artículos este podría decir que se ajusta a muchas de mis necesidades, un adecuado precio y me sirvió como extensión de mi NAS, creando más habías para acoplar mas discos NAS y no tener que cambiar todo mi equipo. Con la conexión USB C logra buenas velocidades y al ser RAID da la posibilidad de acoplar de la mejor manera los discos. Creando un RAID para tenerlos como discos separados o discos unidos y visualizar una sola unidad (aunque con dicha configuración se pierden TB de almacenaje) Lo que me llamo la atención es que hace juego con mi NAS negro en lugar de desentonar el color con los clásicos blancos o grises

It is exactly as described in the description of product. No second thoughts on buying. Using it as partial RAID and simple storage for homelab. For mounting SSDs, screws are provided, this information is missed out in the product package contents. R/W Speeds match the described information.

Muy buen producto, agregando discos duros podemos tener bastante almacenamiento

Easy to use. Fan is less noisy.
