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: The D2-320 hard drive enclosure (a DAS, NOT a NAS) adopts USB 3.2 Gen2 protocol for high-speed data transmission up to 10Gbps. With 2 hard drives in RAID 0, the read/write speed can reach up to 521MB/s (SATA III HDD 8TB x 2). With 2 SSD’s in RAID 0, the read speed can reach 1075MB/s (SATA III 1TB SSD x 2).
- Multiple RAIDs supported: The D2-320 is a hardware RAID enclosure and it supports RAID 0, RAID 1, JBOD and SINGLE which can better satisfy various demands of users. In RAID 1, data will be in a mirror backup. When there is a damaged hard drive, you can directly replace the hard drive, and the data will be recovered automatically. This provides an absolute security for the data.
- Super-large Storage Space: The D2-320 USB storage enclosure can support up to two 3.5" and 2.5" SATA HDD, as well as 2.5" SATA SSD, with a maximum capacity of 22TB per drive, providing users with up to 44TB (22TB x 2) of storage space.
- Better Heat Dissipation: The D2-320 HDD enclosure has an intelligent temperature-controlled and low-noise fan that automatically adjusts its speed based on the temperature of the hard disk. This feature ensures that the hard disk operates at its best temperature and provides better heat dissipation.
- Convenient to swap hard drives: The D2-320 external hard drive enclosure features a tool-free hard drive tray design that allows for easy installation and removal of hard drives without the need for any tools. Furthermore, the D2-320 incorporates a brand new Push-lock unique design from TerraMaster, which automatically locks the hard drive tray when you insert the hard drive, preventing the hard drive from falling out or disconnecting.

### ⭐⭐⭐⭐ 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!
