Customers find the hard drive enclosure relatively easy to set up. They say the instructions are OK and the hard drives are easy to attach and slide in/out. They also mention that configuring the RAID is easy using a rotary switch on the back.

Customers like the temperature of the hard drive enclosure. They say it keeps everything cool and doesn't seem to get too hot. The material choice improves heat dissipation with lower fan noise.

Customers are mixed about the speed of the hard drive enclosure. Some mention it has good speed when it works, while others say that it runs slow when it gets fragmented. The internal raid 0 is faster, while the performance is a bit worse than it could be. The fan speed is adjustable, and it has no lag in accessing files.

"...Internal read/writes are great, 1 external connection is a bit of a miss but not really the end of the world...." Read more

"...Cons:- The Raid software is not included in the box, but it is offered free for download on their website.-..." Read more

"...application still shows the array as normal, but because the software is so basic there's absolutely no way to troubleshoot it...." Read more

"...No additional software was needed. Windows detected the drives in disk management perfectly...." Read more

Solid build, Superior Cooling, Quiet and Some Caveats (see details)
4 Stars
Solid build, Superior Cooling, Quiet and Some Caveats (see details)
Build quality - very solid, the aluminum chassis is sturdy.Cooling - Far better than any other cheaper solution on the market, with full 5 drives (8TB, SMR, 8 header 4 disks each drive), the temperatures I got on all drives average to 30~35 C.Noise - Very quiet, comparing to other solutions on the market. No quantitative result here.Compatibility - good, especially on AMD USB controller.Speed - Solid. I don't run SSDs on it so personally no bottleneck has been seen.Caveats:Weird raid controller configurationFor some reason, the connected drives are masked under visualized SCSI devices called 'DAS TerraMaster SCSI Disk Device' (see picture 1). This makes drive management becoming pretty hard. It's almost impossible to tell disks from each other.4 port USB3.0 controller (see picture 2) - means you only have 4 USB-SATA bridges.The 'raid-capable' disk0 and disk1 are sharing the same USB-SATA bridge, even you are running them as individual disks.I'm pretty sure this will introduce some bottleneck for folks trying to run two SSDs in drive bay 0 & 1.Overall:It definitely worth the premium over other cheaper solutions.I'm giving 4 stars only because the strange SATA configuration it comes with.

5.0 out of 5 stars Perfect addition to NUC running Roon
Reviewed in the United Kingdom on July 19, 2016
I bought the D4-300 to move my music storage from my NAS to directly attached to my NUC which runs Roon (see [...]).

Install was physically easy with 4 x 6TB drives that I had. I selected JBOD and reformatted using the basic instructions. Initialised using standard Windows disk manager actions. Job done.

Transfer rates seemed pretty good at about 100MB/s using the cable provided (USB-C to USB3.0). That is quicker than my NAS and I saw 15TB done in about 1.5 days (didn't keep a close eye for exact time and speeds)

As other reviews note the unit doesn't power down but that is OK for me as the music system is always on here.

So, a week or so into using it I have no issues to report. Recommend.

4.0 out of 5 stars Sturdy, unobtrusive, relatively easy to install, but scary to use.
Reviewed in Singapore on August 29, 2020
The product is generally quite good. The enclosure is hard and sturdy with a nice feel. It is relatively small and unobtrusive. It can house 2.5" drives, but only three of the four screwholes align properly with the 2.5" drives.

I house a single 2.5" 15 mm 4 TB Seagate Barracuda drive which was ripped out of its original exclosure (a Backup Plus Portable Drive) after its control interface board inside failed and the drive did not power up. This allowed me to access my otherwise impossible to access disk. So I am thankful for it.

Putting the tray back into the slot with the disk mounted can be a little tricky at first, but once you figure it out, it is easy to slot in. Just don't try to force it in. It should go in easily, if not you are doing it wrong.

Once plugged in properly, the installation on my Windows 7 machine was rather easy. The necessary drivers were automatically found and installed over the network. (See screenshot.)

Now, here is the scary part.... TerraMaster did not provide a diagnostic software and they do not have one, it seems. So, there is no way to perform drive tests on the disk. Seagate's SeaTools, DiskWizard and Toolkit do not recognise the disk. So I rely on the Acronis Drive Monitor which monitors the S.M.A.R.T. parameters. That's the best I can do for now until I find a software that can perform tests for disks inside this enclosure safely..
