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

I had four 1TB 2.5” drives sitting around from an old NAS box that had failed that I needed to do something with. With the up coming Microsoft changes in October I also needed a system upgrade, so I found the perfect time to accomplish it all. I reviewed lots of different solutions and customer reviews before settling on the Teramaster D4-320 DAS unit, the cost was extremely reasonable, the shipping was fast, the installation was very simple and the performance with the USB-C interface was very good. Before installing on my new Windows PC I did some serious compatibility testing using a MAC which also worked wonderfully. The unit sits on my desktop, makes very little noise and looks good next to the Dell PC. When the time comes that I will require more storage, this unit will definitely e at the top of my list.

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

This thing can get quite noisy while writing files to the disk. But it's not a deal breaker. Took the advice of some other reviewers and added some padding to reduce the noise and it helped for sure. If this thing didn't make such a racket without modifying it, it would be a easy 5 stars. I like the ease of installing drives, the transfer speeds are as advertised, and I like the appearance.

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.

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.

It was always a pain having to swap drives between new pc builds. With this, I’ll never have to worry about that again. Really easy to use, and great build quality.

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 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.
