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

Well I had 5 external hard drives hooked up to my server, I ran out of electrical outlets so I wanted something to change that. This was seamless, I shucked all the external drives and popped them in. Connected the USB-C and started up the server. All drives remained the same drive letter and I was back in business. I added some foam on the bottom as the hard drives have quite a bit of vibration when spinning (Enterprise drives) and this reduced the noise to nothing. Transfer speeds/read write are limited to what the drives can read/write and not what the controller/interface can handle. Overall great product, solved my needs, simple to setup, and I have a free bay for later expansion. The hot swappable feature is also very nice to have.

Didn't work with SMART testing. But after firmware update it now fully functions. Refer Terramaster website for program to update for server compatibility.

In an effort to consolidate my external HDD management, I finally opted to purchase a proper HDD enclosure. I have a NAS for other uses, but I needed something that was a DAS (Data Attached Storage) for different drives that I would be rotating or didn't need on a network. This enclosure suited my needs. USB-C connectivity to my PC. 6 drive bays. Independent power and connectivity; that part is key. With the other 4-bay style top-loading HDD bays, if you pull one drive, the entire unit disconnects all the drives and you have to wait for Windows to detect what is in the other bays. With this particular enclosure, you can disconnect the drive in Windows, and the other drives remain powered and accessible. That's true hot swappablility. It's also going to let you transfer files as fast as the drives you have in there will let them. I should have gotten this sooner. Can't recommend it enough.

This is the third 6+ drive enclosure I'd tried. The first two kept suddenly failing and disconnecting from the PC while writing which required a partition repair repeatedly. They were 2/3 the price, but were garbage. Terramaster is solid and much more compact than the previous units. I did have to buy a USB C to USB A Cable 3.1/3.2 Gen 2, which works great with excellent speed. Ordered a second TERRAMASTER D6-320. Don't go cheap on these enclosures and you'll save money.

Not all enclosures play nice with Mac, this one does. Finding Thunderbolt, is rare, but also that has 6 bays & can handle 20TB drives is harder than you would think. This one handles all of that, and does it well. My only issue is that 10gbps is slower transfer than I hoped for, really wanted 80gbps, but TB5 enclosures are very rare. Even TB4 is very rare at this time. I appreciate the build quality, very solid, the box has some heft to it. The drive trays are all metal, slide in HDD, add 4 screws in the bottom to ensure rock solid stablity. The drives use the lever/latch method, which I prefer, really adds a solid feel and connection, which gives you easy access, and a solid lock down. Power supply meets the needs. The cooling fans keeps things cool, but run quiet. This box is compatible with macOS, Windows and Linux - options abound.
