## Description

Product description TERRAMASTER D6-320 10Gbps USB Storage High-speed data transfer and massive storage capacity: The D6-320 hard drive enclosure features a USB3.2 Gen2 interface providing a 10Gbps data transmission bandwidth. With the capability to support up to six 3.5" and 2.5" SATA HDD, and 2.5" SATA SSD, it offers a maximum drive capacity of 22TB and a storage space of up to 132TB (22TB x 6). When six hard drives are installed (SATA III HDD 8TB x 6 simultaneously read/write), it delivers an actual read/write speed of up to 1,030MB/s, while a single SSD installation (SATA III 1TB SSD x 1) can reach a read speed of 510MB/s. Please note that the D6-320 does not support the function of array and only supports individual disks. Highly Compatible Interface: The D6-320 USB storage comes with a 1-meter USB Type-C to Type-C cable and is plug-and-play, requiring no drivers. It is compatible with a range of computer interfaces, including USB 3.0/3.1/3.2, Thunderbolt 3/4. Hot Swappable, Intelligent Disk Sleep: The D6-320 HDD storage allows hot swapping for convenient hard disk replacement while powered on. It supports the sleep function to reduce power consumption and extend the hard disk's service life by following the computer OS's sleep mode. Better Heat Dissipation: The D6-320 HDD enclosure features a temperature-controlled fan that adjusts its speed according to the hard disk's temperature for optimal performance. Its internal structure is optimized to increase air pressure, reduce hard disk temperature, and minimize noise and resonance. These features enable the D6-320 to operate quietly even under heavy load. Expansion of NAS Storage Space: The D6-320 DAS storage is compatible with TerraMaster NAS via USB interface with proper adaptation. Users can expand the NAS storage space by creating arrays and storage pools on D6-320 through TerraMaster TOS. Note: this feature requires TerraMaster NAS with TOS 5.1 or later version. Note: Some mini PCs may have weaker USB signal output, which can cause random interruptions during file read/write operations during data transmission . When this occurs, it is recommended to 1) use the rear USB ports of the computer, as they typically provide a more stable signal; 2) test the device on another known-good computer to rule out hardware issues on the original PC; and 3) use a 10Gbps USB-A/USB-C hub or splitter with a short 0.3m–0.5m cable to reduce signal loss.

Review: Great 4-disk enclosure - The self-noise is very quiet although there isn’t much dampening for hard drive noise so the actual drives may be very audible. The fans work great and keep my drives consistently below 40C. The case feels a bit cheap because of all the plastic but I kind of prefer this since it’s so light weight. Despite the plastic case, it feels really solid. The case should hold up for years. The lights on the front are really helpful to confirm disk activity. I only have two complaints: how the drives show up in windows and the quality of the USB-C connector. Each drive shows up individually which is great for software RAID, but ejecting the drives means each one has to be removed from windows separately. I wish there was a way to eject them all as one device before I disconnect the enclosure. The USB-C connector also could be stronger. If something accidentally bumps into the cable while it’s in, it can disconnect from the host even if the cable looks like it should still be connected. Despite these concerns, I’m very happy with this enclosure.
Review: Fantastic DAS - But Throw Away the Stock Cable Immediately (1.5-Year Review) - I have been running the TerraMaster D4-320 for a year and a half now, and it has performed flawlessly. My setup consists of four 22TB Western Digital Ultrastar DC HC570 enterprise drives configured in a software RAID10 array on a Linux NAS. It has been so reliable and stable that I just ordered the 2-bay version, the D2-320, to expand my storage even further. However, looking at the negative reviews complaining about random drive disconnects, frozen transfers, and data corruption, I am confident that a huge percentage of these bad experiences come down to one single, easily avoided issue: the factory USB cable included in the box. These 320-series enclosures operate on a high-speed 10 Gbps (USB 3.2 Gen 2) interface. When you are multiplexing data from up to four separate hard drives down a single USB line, the connection is incredibly sensitive to signal degradation. The stock 1-meter cable included with the unit is simply too thin and too long for this specific high-bandwidth hardware specification. Under heavy or sustained write loads, the signal degrades over that distance, causing the data packets to drop. The host operating system loses track of the connection, panics, and resets the drive link - which looks to the user like a random disconnect or a corrupted array. The Fix is Simple: Do not use the factory cable. Instead, replace it immediately with a short, thick, heavily shielded USB cable rated explicitly for 10 Gbps or USB 3.2 Gen 2. I personally use a high-quality 0.5-meter (1.6 feet) heavily shielded cable (the kind typically bundled with external NVMe SSD enclosures). Keeping the cable short and thick does two vital things: 1. Eliminates Signal Loss: Shorter distances mean the high-frequency data signals arrive clean and error-free without the enclosure needing to constantly re-transmit corrupted data. 2. Reduces Electrical Resistance: Thicker copper wires ensure that when the enclosure spikes in power usage during heavy metadata operations, the voltage remains completely stable across the connection. If you treat the stock cable as temporary packaging and swap it out for a heavy-duty, short 0.5m cable from day one, this enclosure is an absolute tank. Highly recommended, just budget an extra ten dollars for a proper data cable!

### ⭐⭐⭐⭐⭐ The RAID1 functions as expected.
*by R***. on December 2, 2024*

I purchased the D2-320 2-bay RAID enclosure with USB 3.2 Gen 2 10 Gbps My purpose with this unit was to mirror (RAID1) two 6TB WD Reds with a Linux machine. I’m not familiar with this brand, so I decided to test it a little before copying a lot of my files over to the D2-320. Getting everything working was pretty easy. I pulled out each bay, installing the drive was pretty easy, no screws needed. They provide a video on it if you’re unsure. I set the selector on the back of the unit to RAID1, shoved in both drives, connected the USB (drives are powered but won’t spin up until the USB is connected), then held the RESET button with the provided pin until the disk lights flashed. The system found one drive - as it should have. I wrote approximately 18K files and directories of various sizes to the array and then without disconnecting the USB or turning off the power, I pulled out one drive. I then connect the pulled drive directly to another computer to see that the files were in fact written to the drive. They were. All good to go. I replaced the drive. Both lights are green. Since no changes had been made to either drive, this is perfect, it didn’t try to rebuilt the array Next, I pulled the second drive out hot. Then connected that drive to the other computer and checked to make sure all files were also written to this drive as well. They were! It is working as it should be. I then created a couple files on the other drive and then replaced the pulled drive back into the D2-320. One drive light was blinking green, the other blinking yellow. According to the online documentation, this means it is rebuilding the RAID1 mirror. Perfect .. Everything is performing as expected. It did take a few hours to rebuild .. but these are 6TB drives, so that was expected. The USB cable provided seems adequate, USB C on both ends. If you need a different cable, consider that when purchasing. Average 1G file write 156 MB/s, average 1G read 221MB/s. Slow but these are mechanical drives connected via USB. Acceptable. Later, I watched a video using Jellyfin and reading, transcoding, and streaming worked perfectly fine. The large fan is quiet and seems to keep the drives cool. Airflow looks to be sufficient. How noisy the unit will be will depend on your drives. Some are louder than others. These drives will be part of a system I have in place which will be up and running 24/7. I’ll be very interested in seeing how well the Terramaster D2-320 performs in the long run. I’ll post updates after I have used them for some time.
