TERRAMASTER D4-320 External Hard Drive Enclosure - 4bay USB 3.2 Gen2 10Gbps Type-C USB Storage Hot Swappable Plug and Play (Diskless)

Works great. Almost totally silent. Easy to install/remove drives. Not sure what else to say about something that works exactly as advertised! (smile)

I recently purchased this to serve as storage for my Plex Media Server. Response time is great! Supports large drives (I have a 24TB drive and two 6TB drives that are a different model than the 24TB in it right now), great value for the price, would absolutely recommend to someone looking for direct storage.

Does the job. Housing the four drives that hold my Adobe ans DaVinci project content. All 4 are WD 7200s. Noisy. Case is thin plastic. Buy a better transfer cable than the one provided.

Received this today. Took about 25 minutes to install 4 drives and power it up. Extremely quiet! It sits at the foot of my chair right now (until I rearrange some things when I get a longer USB C - USB C cable), and I literally cannot even hear it.I needed to do something with my individual backup drives that the USB connectors had worn enough that they were so loose that they'd often disconnect the drive at the slightest bump - which can be deadly to data if the drive is writing at the time. The USB C connectors are much more secure than the stupid "double D" connectors that many external drives use. I removed the drives themselves from their external cases (had to break one, because I could find no way to open it) and installed them in the trays on this enclosure. Didn't even need the included hardware, as the 3.5" drives have nifty side pieces that snap into the screw holes on the drive. (the screws included are for mounting 2.5" drives, not needed for 3.5" drives)So now, just one data cable, with a more secure physical connection, faster data flow (USB C 3.2 [supposedly up to 10 gB/s] vs. USB 2.0 [480 mB/s), and just one one power cord. Plus, drives are hot-swappable, so I can rotate backups to my safe and my offsite storage without powering the whole thing down.So far, so good.

Built a NAS using this and an old Mac Mini running TrueNas and it's been great. I was able to hot swap a disk with no issue. Only downside is it is very "plasticy" - not a lot of metal in this, so it feels a bit on the cheaper side. Particularly noticeable on the levers when pulling a disk and on the plastic snap on mounts. Other than that no complaints. Fantastic for a home office or home lab setup.

I really like it. It’s quieter than expected and it powers on when my Pc powers on. I have three hard drives in it. One 8tb, 16tb and a 24tb. All seem to have no issues and stay cool.

I was looking for a 4 bay enclosure and all my research on the enclosures on Amazon seemed to have different type of issues. This 4 bay enclosure had only 1 review and so I went to the company website to look for the specks. I had to replace a Maiwo 4 bay that stopped working in 14 months and it past its warranty. I decided to try it even though it is more expensive based on what I saw on the company website. So far this enclosure is great. Easy to open and install the hard drives, no screws needed to open the enclosure and truly its plug and play. It is very silent in terms of the fan. It is bigger than some of the others but that gives it plenty room for airflow to cool the enclosure. It is fast in Data transfer but I cannot tell actual speeds. Does not get hot to touch. Vey happy so far. High recommend it.

I really really wanted to like this and tried hard to make this work, but it didn't. Of the 4 bays, I only had 2 HDs connected. There are 2 issues I faced:a) It's LOUD. I mean if you have this thing in another room no issues. And if if it wasn't for the next issue, I would actually be fine with the noise it produced. It sounds like constant rain on Tin Roof.b) The hard drive sleep and spin up time was unbearablePoint b actually got more complex. I had a process that was writing bits/bytes of information to the HD. While that process is running, I sometimes would not be able to access any other folder on the HD. Also, once it would put the HD to sleep, spinning it back up took more than 50 seconds. Unacceptable.Now I tried working with support, to make this work. I have no Sleep settings on the host machine. I also tried writing a small script that would periodically write a line to different locations within each HD. BUT NOPE. This thing would not work. Had to return it and bought a OWC Thunderbay 4. Love it so far. Relatively much quieter and have had no HD sleep issues. Everything is ready and fast. Spin up times are super fast too.
