Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.

AI-generated from the text of customer reviews
Customers are mixed about the performance of the hard drive enclosure. Some mention it's a solid enclosure that is working well, reliable, and sturdy. However, others say that it gets unmountable or corrupts almost every single drive they put on it. Some customers also say that the enclosure is far from good for reliability, and that the back of the enclosure no longer has the heavy duty grounded cable they were used to.

First, I received the enclosure and tested it turning it on with no drives installed to judge the fan noise. The fan produced an annoying rattling noise, frustrating, but nothing beyond what I've heard from other cheap included fans. Thinking myself smart, I thought, "I can replace that" and made my first mistake, buying a nice silent fan. Replacing the fan was not hard, but it did require snipping wires and re-soldering the new fan into place (goodbye chance of returning the unit no matter how many drives it has corrupted). That went fine and I was briefly very happy with my newly ultra-quiet enclosure.
That only lasted until I actually tried to use it. I put 2 new 8 Tb drives in, a 1 Tb SSD, and an old 3 Tb drive, I intended to clone onto one of the new 8 Tb drives and replace, then connected it to my Late 2014 Retina iMac via USB 3. From the start it was a bit flakey, sometimes seeming to take a while longer than I'd expect to mount a drive, but I put this down at first to settling in, and pushed forward. The initial drive clone went OK, but after that I started the process of doing a fresh Time Machine backup of all my drives (including the newly cloned one) to the other 8 Tb drive while also indexing the drives for online backup.
This is where things really went bad. First everything seemed to be going a little slower than I'd have expected, with a scan that should have taken 30 minutes or so stretching over hours, then a couple hours into the process all the drives connected to the enclosure (but not another drive I had connected separately via USB) unceremoniously power cycled and unmounted, then remounted. Two came back, but the third didn't remount until a file system check completed (successfully) which took far longer than I would have expected. After that, the Time Machine backup seemed to have difficulty restarting after its sudden disconnection. I eventually got it restarted, but not long after all the drives dumped themselves again. Again, one of the drives refused to remount until a file system check completed. By this time it was very late, so I left it overnight to try to get it to remount and when I came back in the morning, it was back and all file system checks reported fine.
I shut everything down, unplugged everything and replugged into different USB ports and swapped around the drives to different bays, rebooted, reformatted my Time Machine drive, and started over fresh, pausing the network backup indexing to let it do one thing at a time, hopefully finishing the Time Machine backup before starting the network one. This time everything seemed to be going fine... until the backup was nearly completed. I came back to check on the process and found an error. It didn't seem like the drives and disconnected themselves again, but Time Machine reported it couldn't finish creating the backup and errored out every time I tried to restart it. I unmounted and attempted to remount the Time Machine drive using Disk Utility, but after unmounting it, it wouldn't remount. It wouldn't even start a file system check on it to attempt to remount it. Not only that, but after unmounting it, it could no longer see the name of the drive replacing it with just dashes.
I shut down, power cycled the enclosure, and started back up... and no drives mounted. When I opened up Disk Utility, not only the Time Machine drive, but all the drives attached showed empty name fields, so corrupted that Disk Utility couldn't even tell the names of the drives. I figured, "wow, the controller in the enclosure died and it just isn't reading anything", so I took the drives out and put them in separate enclosures to check them. Still dead. The enclosure hadn't died, it had killed every drive attached to it.
Because it took out both my data drives and my backup drives in the same go while causing me to pause my online backup, I'm going to have to see if I can do data recovery to get my data off of the drives. Some preliminary looking makes it seem like I may be able to get my data back, but I'm having to throw more money at the mess this enclosure has made to buy updated data recovery software (while waiting unable to do work until I get it). And, of course, I'm never letting the enclosure touch another drive again, so I'll need to buy another solution. But the best part is that because I shelled out to upgrade the fan, I doubt I'll be able to recover anything I spent on the evil drive killing beast.
So I don't know. Maybe I got a lemon. Other people seem to have had fine experiences. But I'd strongly encourage you to do some burn in testing with drives that don't have any data you care about on them before trusting this enclosure. And if you think, "that fan's noisy but it doesn't look hard to replace" you're not wrong, but wait to see if you're going to want to return the thing first.
The conditions where they failed miserably (on all machines) was when I combined 4 SSD drives from different manufacturers; (Intel, Samsung, San Disk and Crucial). After full formatting (Disk Utility, Mac OS Extended) several times, one or more drives would simply not mount on boot, or fail altogether. In one instance, the failure wiped out the drive and it’s contents (Crucial SSD, 1TB). I did find one workaround which seems (so far) to be working. On Mac machines, do not boot and/or shutdown with the Icy Dock on. If you firstly fully boot your machine, then turn on the Icy Dock, things appear to work OK. I believe it may have something to do with MBR or disk-to-disk instructions differing on each of the drives, i.e, one using NAND, the others 3D, or something similar. I cannot be sure. Boot readouts were also sketchy (using the Terminal to log errors). I'm using the setup for storage, so performance issues do not concern me here. I fill a drive and then remove it.
I have not tested it on Windows computers, yet. If there is any change, I’ll post here. In the meantime, if you need reliability for Mac platforms (especially when working with video or music), I suggest some other JOBD setup.
ICYDOCK did make one change that is quite irritating however. The power cable that goes into the back of the enclosure is no longer the heavy duty grounded cable I was used to. Now it's a skinny cord that runs to a power brick, something you'd typically see on a laptop computer. The plug is now easy to dislodge from the back of the enclosure, which means that one day I will inevitably knock it loose, cutting power to all the drives in the bays. I'm going to secure the plug in place with tape, but needing this kind of makeshift arrangement is not what I expected from an otherwise sturdy and reliable product.
It's a great JBOD enclosure, it keeps the drives cool (WD Red, various sizes), and the fan is way quieter than the air filter I have running in my office.
The second one was purchased because the number of drives I have keeps growing.
(I'm not a fan of deleting things, I'd rather my disk space grow. I'm up to about 54TB now.)
