  • Awesome Product!
Capacity: 10TB
The device is priced great for what you’re getting. It does emit a loud-ish hum but I keep it inside the cabinet with the router. The set up was super easy, just plug and play. I use it to store all of my PC games. Huge storage space and the usb-c 3.2 connection lets me transfer games between my SSD and HDD super quickly. I was originally going to use it for games I don’t play too often but it works amazingly well, I play my games directly from the HDD with no issues at all. I highly recommend this to anyone that needs a huge storage boost with a low price point. ... show more

  • Good but crashes some times
Capacity: 14TB
It's great but it crashes some times. Idk if it's just the gaming I'm playing but so far it's the only game I have played on it and when you leave it on pause for awhile or quick resumes after turning you console off it will crash. The game is Teeny Turner's wonderland.

  • Great for the Price - but Kinda Loud
Capacity: 10TB
I got this 10TB hard drive for a great price. It is a little bulky but not too bad. Works with Mac OS just need to reformat the drive initially, which was very simple with Disk Utility. The only drawbacks on this device - it is a little loud when it starts up and winds down, and it also slightly vibrates the desk as well. I don't think had I known this before would I have not purchased this product, it is just slightly annoying at the moment. ... show more

  • UnionSine 8TB External Hard Drive Failed Within 3 Months - Lost Hundreds of Hours of Work
To give you guys an idea of what a working hard drive means to me, I am a YouTuber with ~100k subscribers. It's like a mini-business, with a fair amount of cash earned from YouTube partnership. As a result, I need a good amount of extra storage space and substantial reliability, though I also need a good price. I thought I found the perfect combination of all of those things with the UnionSine 8TB External Hard Drive. While it worked decently enough at first, though was so noisy that even non-tech-savvy people noticed and thought there may be an issue with it, I was assured by the directions including in with the hard drive that such loud noise was supposed to happen. For three months, I was able to stream data with no issues straight to the hard drive at a high rate, sometimes capturing hours of 2K quality footage in a single day. Then, right when I was about to release arguably my biggest video in months, the hard drive failed. I went to sleep right after I finished the video with the idea that I could just upload it in the morning, but I could not have been more wrong. I turned my computer and external hard drive on, and it sounded substantially different than normal, as though it is no longer turning. It even made my computer turn on and shut off SUBSTANTIALLY slower, which is noticeable as I have an SSD that I use for my OS. It was giving my computer such fits that my computer wouldn't shut off until I removed the USB plug from it that was attached to the UnionSine external hard drive on the other end. Turning on my computer took approximately 10x as long as normal. I tested it to see if it was the failed UnionSine hard drive that was giving it fits, so I booted and shut off my computer WITHOUT the UnionSine external hard drive connected, and it turned on and shut off as normal. In short, I absolutely DEPEND on a quality hard drive that works and can store a good amount of data. This hard drive failed when I needed it most, and I hardly had 25% of the hard drive filled with data. I was probably hovering around 6TB free when it failed, which, along with how quickly it took for this to fail, is incredibly shocking. Meanwhile, I have an EXCELLENT 5TB Western Digital Black external hard drive that is over a year older than the UnionSine, and it still works like clockwork, and I have NEVER had an issue with it, or another, smaller version of that same WD Black external hard drive that I purchased years before that. Worse yet, I don't even move the UnionSine external hard drive, it stays in the same spot as it has since I first operated it. I would recommend ANYONE that needs to have reliable storage stay away from UnionSine. Mechanical hard drive technology is DECADES OLD, and has NO EXCUSE for breaking within months of usage, especially within so much free space still left on it. Avoid this brand like the plague, and go for a more reputable brand, like Western Digital or Seagate. ... show more

  • Good
Capacity: 10TB
It was super easy to use it with a laptop. This had type-c to USB and type-c to type-c connectors. It was super helpful to transfer data from my phone directly to this data storage. data transfer for a giga bit of data was super quick in my test transfer. There's not much noise that I noticed to my surprise. Been loving it so far. ... show more

  • Excellent External Hard Drive!
Capacity: 10TB
I recently purchased this external hard drive from Amazon, and I couldn't be happier with its performance. Here's why I think it's fantastic: The advertised speed of 120mb/s caught my attention, but I was pleasantly surprised to find out that the actual speed exceeds expectations at around 200mb/s. It handles data transfer effortlessly and has significantly boosted my workflow. Not only does it work exceptionally well, but it also looks sleek and matches perfectly with my black Alienware setup. The design is not only functional but also aesthetically pleasing. It seamlessly integrates with my devices, and the compatibility with my Alienware is spot on. It's always great when technology not only works well but also complements the overall setup. So far,. I've had no issues with data storage. In conclusion, this external hard drive is a fantastic addition to my tech arsenal. The actual speed exceeding the advertised specifications is a delightful surprise, and its sleek design complements my setup perfectly. ... show more

  • Plug and Play with Linux
Capacity: 16TB
Requires outboard power supply, which is included in the box. Saves your laptop from having to supply the power from it's small power supply. NTSF formated, a breeze to use Love it. Bought a second one. Better than paying monthly fees for cloud storage.

  • Noisy HDD
Capacity: 10TB
My old external hard drive was being filled up with my data so decided to buy a new one. The reviews for the UnionSine 10 TB were promising. It came well packaged. I plugged it in and connected it to my Mac and then formatted it and began transporting data to it. Ease of use -- great. The storage is wonderful. My only complaint is that it is noisy. It thumps and clunks when being written to. Then as it just sits there, it clicks every 5 - 7 seconds. This is quite annoying since I suffer a bit of misophonia. I can't have this plugged in making that noise. It doesn't make it entirely useless but it certainly makes it inconvenient. ... show more
