    • Easy to install on my Dell laptop
Capacity: 2TB Color: Black
I love the small size of this external hard drive and its 2TB capacity. I have tons of digital files and my computer was running low on storage so I started looking for an external hard drive. This one fit all my needs and was competitively priced. So far it is working great and my computer is running much better without being clogged down by the files. ... show more

    • Seems good so far…
Capacity: 750GB Color: Black
It is much smaller than I thought it would be, and seems put together well enough. Definitely not rugged though. It connected to my Xbox and was instantly recognized and ready for formatting which went super smooth. The speeds are very close to what they are advertised as. I got an average of about 710-750 Mbps which is close to the converted advertised speeds of 800 Mbps. It does get a slight dip in speeds around the first 10 seconds and last 15 seconds of a transfer, but it only fell to 650 Mbps which is still fast enough for me. Very good value for money. Also does stay relatively cool during sustained transfers however it did eventually begin to get a little bit warm, but not concerningly warm or anything. My drive did only come with 698 GB when it should have come with 750 GB, but overall seems like a great product. ... show more

I use this with my MacBook Pro and it has worked perfectly. Fast transfers and great for saving storage space on my Mac. I can work on files stored on it without having to transfer them back on to my computer.

    • Pretty decent!
Capacity: 320GB Color: Pink
Not the fastest thing and does get a little warm, but so far so good! It’s saved data and has been easily portable. I think this is good for an average hardrive and if need be I wouldn’t mind buying another one.

Review Image by Belina Belina
I recently purchased the UnionSine 500GB Ultra Slim Portable External Hard Drive, and overall, I’m quite pleased with my choice. The design is sleek and stylish, and I love the pink color—it adds a fun touch to my tech accessories. Setting it up was a breeze; I simply plugged it into my laptop via the USB 3.0 port, and it was recognized immediately. The transfer speeds are impressive, making it easy to back up my files quickly. The 500GB capacity is more than enough for my needs, allowing me to store a large number of documents, photos, and even games without any hassle. However, the only reason I didn’t give it a full five stars is that the drive does feel a bit fragile, so I’m a little cautious when handling it. It would be great if it came with a protective case or more robust construction. Overall, if you’re looking for a stylish, portable, and efficient external hard drive, I highly recommend the UnionSine 500GB model. It’s perfect for anyone needing extra storage on the go! ... show more
