Customers say
Customers find the external hard drive works well, particularly with Xbox Series S, and appreciate its compact size that saves space on laptops and desktops. The drive provides plenty of storage and is easy to set up and use. While some customers consider it a decent product for the cost, others find it a waste of money. Durability and speed receive mixed reviews – some say it’s well-made and speedy enough, while others report it breaking easily and being extremely slow. Compatibility is also mixed, with it working well with PS4 and systems but not with new generation Xbox consoles.

Review of UnionSine 750GB 2.5″ External HDD
I actually bought two different 750 GB external Hard Drives (HDD). The UnionSine 750GB HDD is mounted in what resembles a metal heatsink. The entire case is all plastic and solid. I decided on HDD for 2 reasons. 1. I needed more than 500GB but 1 TB was too much. 2. I wanted drives for long term storage.HDD is different from an SSD (Solid State Drive) in that the HDD is a mechanical drive with spinning platter and a movable head. HDDs are not as rugged as SSD and they require more power (current). The UnionSine 750GB drive comes with a USB cable with a USB-A on the computer end and a USB Micro B on the drive end. This cable provides more power for the HDD This cable not only provides more power, it also increase the data transfer to drive if the computer has v 3.0 USB.An HDD will maintain the data for a longer period than SSD as long as it is not dropped, bumped, or josteled. An SSD drive basically charges and discharges internal solid state cells. The charge will last about a year or so if the SSD is left unpowered. For cloning and archiving, an HHD is better unplugged and stored away. An SSD should be powered every so often.The UnionSine 750GB came in it’s own box with a 3 yr warranty. The HDD is an Hitachi Global Storage Tech drive. If you buy this exteranl HDD you may or may not get an Hitachi HDD. I am guessing they buy a batch of 2.5″ drives at the best price so it could be any brand. I ran a HDD test and it came back with perfect status. Problem and/or weak sectors not found. No spin up nor data transfer errors. Internal temp was 20 degrees C.The S.M.A.R.T. came back passing all tests.Either drive will do a good job.

Compact, Fast, and Reliable Storage Solution!
I’ve been using this 1TB external hard drive for a few months now, and it’s been excellent. I am very happy with this purchase.It’s super slim and lightweight, making it easy to carry around with my laptop in a laptop backpack.The USB 3.0 connection offers fast data transfer speeds, and it worked instantly with my PC. I am going to buy another one for my son’s PS5. Stay tuned for that review.I’ve had no issues with compatibility or performance and 1 TB seems to offer more storage than I currently need.Definitely a great value for anyone needing extra storage on the go!

Great for storing Pc Games- Fast, Reliable and Compact
I bought this external hard drive to expand the storage on my gaming PC, and it’s been a great investment. It connected instantly with no setup hassle, and transferring my game files was quick and easy. I’ve been running several games directly from the drive with no lag or performance issues. It handles large files smoothly and keeps up with my needs during gaming sessions. The slim design also fits nicely on my desk without clutter. For anyone looking to boost their PC game storage, this drive definitely does the job.

Make sure you’re cool with it’s cables
Device is good, well priced, and does what it says it does. Make sure you read about the cabling for the if you decide to buy it. I just assumed it was USB-C. It uses a weird cable I’m unfamiliar with that ends in a USB-A male (big rectangular).My laptop doesn’t have any USB-A jacks and hasn’t had any for years, so I had to drop a couple bucks on an adapter (USB-A to USB-C). And I’m a little nervous that if I lose their little custom cable I won’t be able to use the device anymore without buying some special cable.Oh well. It works and the price is right.

a great value ever!!
I recently purchased the Black Portable External Hard Drive for my son, and it’s been a solid performer.It’s a sleek, minimalist design. It’s lightweight, making it perfect for travel or everyday portability—easily fits in a laptop bag or even a jacket pocket.The setup was seamless.At 500GB, it’s not the largest capacity out there, but it’s perfect for backing up essential documents, photos, and a moderate collection of videos or games. It runs quietly and doesn’t heat up excessively during extended use.Overall, this drive is a great value for the price. It’s a dependable, stylish, and portable storage solution for users who need moderate capacity without the bulk.Would recommend.

Storage for Your PS5
I bought this for my PS5. I had to look up where to find the storage in the settings, once turned on but that has nothing to do with the quality of the product. The drive was immediately connected to the game system and I was able to move games I no longer played onto it without a problem.I love that it is lightweight and black so it doesn’t look like an eyesore on the TV stand. I hardly ever notice it.I’m glad I bought the drive with the most storage from the start!

Good storage and seems well made. Hence, no complaints here. It comes with everything you need to use it so you don’t need to worry about immediately putting it to use.I use it to back up my hard drive, and it works fine for that. Note, it is a brick, but that is what you should expect from such items.
