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.

1.0 out of 5 stars UnionSine 8TB External Hard Drive Failed Within 3 Months - Lost Hundreds of Hours of Work
Reviewed in the United States on October 14, 2023
Verified Purchase
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.

3.0 out of 5 stars Noisy HDD
Reviewed in the United States on March 22, 2024
Capacity: 10TBVerified Purchase
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.

I really like the build quality of this external hard drive. The plastic shell feels durable. I am also surprised they include two data cables for type c and the old USB A. I tried the type c cable with my Samsung phone and it can read data as well! The disk comes in NTFS format and I think later Android update will support write to the disk as well.

I like the minimalist design. Better than the big brand design that collects fingerprint easily. The speed is fast and consistent. Noise is acceptable. Also the design has wide holes for ventilation. Overall, a very good alternative compare to the big brands.

Produto parace bom, mas já aconteceu, em pouco tempo de uso, de não ser reconhecido pelo notebook! Até o momento desta avaliação está funcionando!

É útil, compacto e vale o preço.
Pra quem for comprar, eu diria pra ficar atento, pois (pelo menos pra mim) q taxa de transferência de dados foi de 25 mb/s

This is my first time I am using this product so I will be short and blunt. Well packages, promt delivery and value for money. So far the performance has been great. I did not rate sleep mode as I am not a technical person, so I do not to mislead by my ignorance, both in favor or against. All I can say I am very happy with this product and after I will use for 3 /4 moths, if still available I will buy another one. Once again, for my knowledge and daily use, awesome product and value for money.
