Excellent product. It immediately recognized the disk (Western Digital Red NAS 3TB) when I connected it to an Android box (Tanix TX6) on the TV, something I couldn't achieve with another older Transcend enclosure I had. Also, the disk does not seem to heat up, even though it does not have a cooling system. Installation is very easy, it literally takes less than 1 minute to connect the disk. Highly recommended.

This UGreen is a beast of reliability and quality. For years I've trusted various cables & chargers and now that I needed a case I decided to choose this one again. The hard drive snaps in easily without difficulty onto the pins, but firmly. It has an ON/OFF button, but if you want the hard drive to be immediately on standby and available in case of a power outage or computer restart, you should leave it permanently on. It is completely silent (of course, this also depends on the hard drive).

It has everything you need: on/off switch, good power supply, USB 3.1 cable, and it is lightweight.
I would NOT recommend it for permanent use but for occasional disk testing, data transfers, cold storage, etc., as it does not have any kind of cooling.
Exceptions are the 'slow' drives that run at 5400 and do not heat up.
It has been tested with drives from 500GB up to 26TB.

Satisfactory solution to turn an internal hard drive into an external one! It is important that no tools are needed to insert or remove the drive from the tray, which makes it a quick and easy solution for everyone. Likewise, the fact that there is an on/off button is convenient. A power adapter and a connectivity cable (usb 3.0) are provided. The transfer speed seems good, although I haven't really done any measurements. I haven't noticed any temperature issues so far, at least nothing noteworthy or concerning.

There is nothing particularly negative. It was used to utilize the hard drive from an old computer and to transfer files. Easy connection of the drive with the internal slot of the case and good connection with the computer. File transfer is quite fast, although I do not know if this is due to the capabilities of the case, the drive, or the computer. It also requires a power connection, so it can be used as a permanent storage extension for the computer, with the advantage that you can have multiple drives and easily connect and disconnect whichever one you want.

The only negative is that after a power outage it is off and you need to press the button to start it. So it's not really suitable for NAS (unless it's on a UPS, then OK), unless the button is short-circuited.

It is plastic. Its quality will show over time.
Easy disk swapping, no screws needed.
Worked perfectly with many HDDs.

The build quality could be better. With the one and only disk I tested it with, I had many sudden disconnections and generally not a good user experience at all. However, it might just be an issue with that particular disk. I will update after testing it with others as well…
Update 13-12-2025. The case works just fine. Apparently, the problems were caused by the USB hub I was using. No problems and the speeds are very good. Overall, I now have a very good opinion of this company's products.

Within a few seconds, you can make your HDD external. No tools are needed and the build quality is "ok". I would like a bit better ventilation for the HDD but it doesn't cause any problems so I won't deduct a star.

I wouldn't recommend it for a 10,000 RPM HDD because it won't absorb the vibrations and the HDD will be very noisy.

All good, I wanted to check some old disks that wouldn't start, I got the files I wanted. It met my needs.

Positives:
- Ugreen build quality
- Good speed
- On/off button
- Tool-less, sliding cover, soft internal pads for vibrations
- Comes with power supply and USB 3.0 A to B cable

Negatives:
- Bulky
- Gets a bit warm

Overall, very good. It does its job.

It does its job just fine, but it would be good if it could be placed vertically and have more anti-vibration features. You put an old hard drive inside and the whole desk vibrates while it operates, it would be good if this could be addressed from a design perspective!

I just received 2 pieces. They do not have the same quality as the icy box and I still do not know if they have a good chip and support unlimited capacity. I will take out a 40 terabyte hard drive from the desktop to put it in and I will come back with a new update

Excellent, it revived my Seagate 8TB external hard drive when its original case "gave up the ghost."

It opens sliding, it has a cushion inside that keeps the disk stable. The disk is inserted with a click. You don't make any effort, neither screwdriver nor wiring. I don't know if the case is durable, I will see in the future. I bought two identical cases for 3.5 disks and another two for 2.5 disks. As it seems, I will only be buying ugreen cases from now on. I am attaching a photo, the orange part at the bottom I still don't understand what role it plays. If anyone knows, please let me know.

the product is worth it
I also have an icy box but I didn't expect this to be better.
better response and speed.

The best for hard drives 3.5". Accepts any capacity and super fast (I have seen a peak of 160Mb/sec in copying)

It saved me from the hassle. When I wanted to connect an old drive, I had to open a case to find cables, motherboards, and other complicated stories. Here, you simply open the case and put in whatever drive you want. SSD, HDD, mini HDD.

It worked immediately with a Toshiba 3TB HDD 3.5" that I had movies, music, and pictures on, and I connected it to the TV. Much higher quality construction than it appears in the pictures. The cables are thick and a bit stiff to adjust. Very simple to set up (you don't need to insert it at an angle), you slide open the lid, put the drive in first (NOT directly into the socket) so it rests on the black foam inside, then slowly slide it to connect it to the socket, finally slide the lid closed and connect the enclosure to the device you want. The speed is also very good, a bit slower than having it inside a desktop (but I don't care for the use I will make of it), but fully responsive and fast enough to get the job done. Anyone who needs the enclosure just shouldn't even think about it. It works super!
Edit 12/2/2026: I used it with a 2.5" HDD and also with another 3.5" HDD and it works fine after a year of use. Additionally, it cleans very easily with a microfiber cloth.

While I already have 2 from the previous revision, this time, it doesn't work straight out of the box. After testing 3 functional drives, I changed the USB 3.0 cable and everything was fine. So before you return it, try a new cable. The downside is that a good USB 3.0 A/B cable can cost around 10 euros. Try to find one from a monitor hub from someone you know who doesn't need it so you don't waste extra money.

I bought this specific device for backups. I can confirm that it works normally with a 20 TB disk.

I got it because for some reason the external 16 TB hard drive I got inside the computer wasn't working. Apparently, there are such issues. As soon as I connected it, it recognized it and has been working perfectly since then at the maximum speeds that a USB port can offer

Very good design and very good construction quality of materials and fitting of the discs. The discs fit perfectly and easily into the case without rattling and buzzing, etc. Practical on-off switch

Very easy to install and the best for the gold one I wanted, permanently connected to the back and when I want to use it I just press the button and turn it on!

The only case that fits large drives. I put an EXOS 18TB inside and it recognized it normally. The only downside is that while it has a very nice design, it is not convenient to stack another one on top because the power button is on the top.

So far it works perfectly, I use it for the backup drive of the main drive I have for photos-videos, it has an on-off button, I keep it permanently connected and just press the button when I need to save something. The drive fits nicely inside, it's worth it fully.

It does exactly what it promises. Very easy installation, you just put it in and it clicks. Plug n play

It is an excellent choice for anyone who needs a reliable and quality hard drive case. I highly recommend it!

Really plug n play, very easy to install the hard drive (4TB) and immediate recognition by the computer.
I use it connected to a miniPC that I recently bought, not only as a storage for torrents, etc., but also for the files I work with daily. Minimal delay in opening the files the first time (I assume when it is in some form of idle state), but afterwards I don't notice any significant delay - of course, you shouldn't expect the same response as with files stored on an internal SSD, we know what it is intended for.
Fully satisfied so far (2-3 months), I would definitely buy it again.

Amazing case, you change the discs on the fly. I bought two and have been using them for a week now. They work perfectly. Compared to the previous case where you had to screw in 8 screws and they all had to be properly aligned, with this case the discs change in 10 seconds.
