    • Excellent External Hard Drive!
Capacity: 10TB
Review Image by K.W K.W
Review Image by K.W K.W
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

I use it for storing large photo files. It has a good read write speed. I usually buy a different brand so this was my first with this company. Seems to be good quality. Working well so far.

    • Interesting External HDD
Capacity: 10TB
Data Transfer Speed/Read: 220mbps to 270mbps (Type-C to Type-C only) [Fastest Transfer and Read Speeds] {4K Ultra HD Support} 6mbps to 34mbps (Type-C to USB only) [Slowest Transfer and Read Speeds] {Not For Ultra HD Content} Size: 10TB (9.09TB Usable) Type: Mechanical (7200RPM) Purchase Date: September 11th, 2023 (day after my birthday lol, it was my birthday gift from my folks) It is somewhat noisy as it does make a lot of sounds which is normal for External HDDs however the knocking seems to be fairly normal as well for this specific External HDD as lot of others I read also seem to have knocking sounds. I would heavily advise using Type-C to Type-C if you want faster transfer speeds however keep in mind not PCs support Type-C to Type-C Connections as older models likely will not and not all will support 220mbps to 270mbps data transfer speeds as it heavily depends on your PCs Type-C Port. (I learnt this recently from connecting it through USB to my Laptop then through Type-C which I have personally found that Type-C is significantly faster) 4K Ultra HD requires a reading file speed of 30mbps or faster and it must be continuous so do not try to watch 4K Ultra HD content unless you use the Type-C to Type-C connection only as the other method will not be fast enough nor steady enough to support Ultra HD content. I have bought the 10TB one and it does make some knocking sounds when being used or just out of the blue like when not in use which is rather alarming as knocking sounds are typically bad with External HDDs however it has been fairly solid for me. I use the Type-C to Type-C cord that comes with it and I get an average speed of around 220mbps to 270mbps which is rather fast for an External HDD however I do frequently get that I/O Device error message which can be frustrating especially when trying to transfer over files (it is fairly rare I get that message however). This device does not always show up on my 2019 Acer Predator Helios 300 and sometimes I have to plug it into my Xbox Series X to get it to work then I can unplug it and plug it back into my 2019 Acer Predator Helios 300 then it shows up as "External HDD (E:)" however it does not always stay active on my laptop and does occasionally disconnects itself then reconnects sometimes later. (Moderate chance but does resolve itself somewhat quickly) [It has never disconnected from my Xbox Series X yet however, I put yet as one may never know in the future and I've only had this HDD for about a month] ... 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
