Review: Now my Mac M4 Mini NAS is good enough to go live. - 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.
Review: Incredible alternative to NAS and super easy to use - 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.

## Features

- High-Speed Data Transmission: The D4-320 hard drive enclosure (a DAS, NOT a NAS) utilizes the USB 3.2 Gen2 protocol, achieving high-speed data transmission of up to 10Gbps. When equipped with four hard drives, the actual read/write speed can reach up to 1,016 MB/s (combined read/write with four SATA III HDDs of 8TB each). With just one SSD installed, the read speed effortlessly reaches 510 MB/s (SATA III 1TB SSD). The D4-320 supports a single HDD up to 30TB, with a total capacity of 120TB, and is compatible with various hard drives, including 3.5-inch SATA hard drives, 2.5-inch SATA hard drives, and 2.5-inch SATA SSDs.
- Plug-and-Play Compatibility: The D4-320 USB storage supports 4 individual disks (NO RAID function), and is plug-and-play, eliminating the need for drivers. It is highly compatible with MAC, Windows, and Linux operating systems. The USB Type-C interface supports various computer interfaces, including USB 3.0, USB 3.1, USB 3.2, Thunderbolt 3, and Thunderbolt 4.
- Hot Swappable Convenience: The D4-320 HDD enclosure supports hot swapping, allowing users to replace hard disks without powering off the device. This feature enhances convenience and efficiency in data transfer processes.
- Tool-Free Hard Drive Management: Featuring a tool-free hard drive tray design, the D4-320 external HDD enclosure enables easy installation and removal of hard drives without requiring additional tools. Furthermore, the D4-320 incorporates TerraMaster's unique Push-lock design, automatically securing the hard drive tray upon insertion, preventing the hard drive from falling out or disconnecting.
- Efficient Heat Dissipation and Quieter Operation: The D4-320 direct attached storage incorporates an intelligent temperature-controlled fan for optimal heat dissipation. Additionally, specialized sound-absorbing panels and vibration damping measures contribute to a quieter operation, with noise levels reduced by up to 50% compared to the previous generation. In standby mode, the noise level drops below 21 dB(A), creating a remarkably quiet user environment.

### ⭐⭐⭐⭐ Great DAS enclosure works as intended but has some negatives. See below
*by V***X on November 17, 2023*

This is a new model DAS enclosure that Terramaster recently released that supports USB 3.2 10Gbps compared to the older model which is 3.1 5Gbps It works great as intended but there are a few negatives. First of all I bought it specifically because it supports USB 3.2 but it only came with a USB C to C cable. USB 10Gbps is still supported with USB A so I had to buy a separate USB 3.2 C to A cable separately. They should have included one of each for the money you are spending. The biggest negative for me is that the Power button is located on the BACK of the unit compared to the front on the previous model. Why? So it looks sleeker? I don't want to have it powered on all the time even in 'sleep' mode. They should have kept the power button easily accessible in the front. The SINGLE and JBOD RAID settings are a bit confusing. JBOD (Just a Bunch of Disks) will create a SINGLE volume of both disks combined. SINGLE will have individual volumes (separate disks) Those are my main gripes but here are the positives. Biggest positive is that it works perfectly with both my Enterprise grade drives. A Seagate EXOS and a Western Digital Ultrastar. The Tool-less drive slots are very easy to use and make it very easy to remove or swap. It has big pliable rubber feet with soak up all the vibrations to minimize hard drive noise. The fan is very quiet and provides adequate air flow, and overall the unit looks very sleek. Overall it's a nice unit and does exactly what I needed it for despite the negatives. Hope this review was helpful!
