D4-320 (4bay,non-raid) I've been using it a week and so far it's worked well.Well packaged, new black design is nice, very on trend and is better in the flesh than in the product visuals. The case is metal with plastic front and back. Power unit/transformer is good, proper fused UK plug with shielded live and neutral (I mentioned this as sometimes these things come with dangerous/illegal plugs).HDD Sata fits into the tray without the need for tools, clips in. SSD Sata screws in with provided screws, you will need small screwdriver. Fan is effective and quiet. USB3.2 works as described but obviously restricted by the speed of the drive you choose to use. I am using this with a Mac 13.6.6 and I have also tested it on an M2 Mac and it works on that as well. I am using a Samsung SSD and two Seagate Ironwolf HDD. The SSD gave me (485MB/s write) (523MB/s read) and the HDD (161MB/s write & read). The SSD runs silent HDD a bit noisy but that is the drive and to be expected. The sleep feature works well, drives remain mounted and when you click on them they wake up. Only niggle was no instructions in box, you are directed online with a QR code and you have to give them your email, I think this might possible extend the warranty but it's unwanted data capture. They have a recommended drive list on their website its for the D4-300 but I assumed it was still relevant. If your using Windows you can download their backup program. I'm just using it as JBOD. Top line - Im very pleased so far, hopefully it will prove reliable. Only time will tell.

Technology is advancing so far these days sometimes it's hard to keep up. And it seems that there is no area of technology that is under development. That's why a box with four spinning disks in it seems like going back to the stone age in tech terms, but as any rabid Redditor well tell you there is no substitute for bang for buck, resilience, and longevity than spinning disks in an array as a means of backing up your data ( ps always remember the 3, 2, 1 backup rule - Startpage search that if you don't know what that means).What I like about this unit is that it is JBOD or just a bunch of disks and that means maximum versatility. Avoid similar disk housings that have built in raid functionality because if the box fails you're stuck with your data locked into whatever proprietary raid came with the box.I had four spare disks from a previous nas and they fitted and initialised no problem. The unit connected to the back of my nas via the included usb cable - another bonus as the cable isn't proprietary if it needs replacing.So far, so good. Also good is the build quality. I have to qualify that statement in that the build quality is acceptable for the price. The plastic silver outside shell comes over as being brittle and cheap. However, the disk mounts and disk bay closure are perfectly functional and to be honest that's where quality should be focused.On to the not so good then. This unit is noisy from fan noise, spinning disks, and in my unit there was a particularly annoying rattle from the chassis, probably due to those brittle plastics being affected by vibrations from all the spinny bits. So I would recommend tucking this unit away under the stairs, or somewhere else or of earshot.So there you have it. Agricultural tech in a new-ish housing for four spinny disks in a box. Yes, it's not the cutting edge, but that's a good thing when it comes to reliably storing your precious data.

This is a really good device. I fitted four large SATA 3.5in discs and it booted up immediately. It has the advantage over some other devices of this type in that it shuts the discs down into sleep mode when not in use and turns off when the computer shuts down, so reducing electricity use. I would certainly recommend to anyone wanting to use their older discs.

Initially this came with a lot of promise and worked for a week seamlessly. Then for some reason one of my 4tb drives disappeared and became unallocated space. This happened twice with it taking over a day to restore fortunately from a back up. With a bit of internet searching apparently it’s a common issue which Terramaster hold no responsibility for. Safe to say, once bitten, twice shy, it’s going back. BE VERY CAREFUL. If you don’t have a back up you could lose a lot of data with this.
