– UnionSine External Hard Drive 500GB Ultra Slim Portable Hard Drive USB 3.0 HDD Storage Compatible for PC,Mac, Laptop, Xbox, Xbox one, PS4(Black)

Bought the 1TB version a few weeks ago because I needed some extra storage for my laptop and PS4. So far it's been doing exactly what I need it to do. It was literally plug and play, and my PC picked it up straight away. I've moved a few hundred GB of photos, games, and work files onto it and haven't had any issues. It's pretty slim and doesn't take up much space in my bag, which is handy because I take it between home and work. The transfer speeds are decent for an external hard drive. It's not the fastest thing in the world, but for backups and storing games it does the job well. It also runs quietly and doesn't seem to get very warm. For the price, I honestly can't complain. If you just need reliable extra storage without spending a lot, I'd recommend it.

A nice looking compact unit that's easy to carry around. I was pleasantly surprised at the very reasonable price bearing in mind the capacity. A short cable is included, setting up is very easy just like plugging in a memory stick. I've had no problems at all & can recommend it.

I have 4 stars for this product. On first use everything is as should be. Arrival in time in perfect packaging. Will update after use in a few month

Worked as stop and start program

I've been using this hard drive for a little while now, and it's been a great purchase. It's incredibly slim and lightweight so it easily fits in my laptop bag without taking up much space. Setup couldn't have been easier, I just plugged it into the USB port and it was ready to use within seconds. I've been using it for backing up photos, documents, and a few larger video files and the transfer speeds have been fast enough that I'm not left waiting around. The build quality is better than I expected for the price. The casing feels solid, and the drive runs quietly without getting overly warm during longer file transfers. I also like that it's compatible with different devices, so I can use it with both my laptop and game console when needed. If you're looking for an affordable, portable hard drive for everyday storage and backups then this one offers excellent value. I'm very happy with my purchase and would definitely recommend it.

Setup was simple, with the drive being recognised straight away when connected. The build quality feels excellent, and the drive appears well protected for everyday use.

This is an absolute rubbish product! I just received it today and needed to clear space of my laptop for it to work better. I transferred a whole lot of pictures and documents to the external hard drive which I thought was worth purchasing after I read the reviews. But, shortly afterwards I heard a clicking sound which now does not stop and all the folders I created with important documents have all disappeared. I was hoping it would come back but to my horror it hasn't. How can you be selling a product that is supposed to be working to keep important information, but it is so faulty. So what am I going to do now? I wish I could get back all my docs but I don't no how. This is really unbelievable. PLEASE DON'T TOUCH THIS USELESS DRIVE, IT WOULD BREAK YOUR HEART. BUY SOMETHING ELSE THIS IS USELESS! A highly disappointed customer. I would like a refund now and compensation for loosing all my files.

This 500GB external hard drive is compact, lightweight, and very easy to carry around. Unlike older external drives, it runs quietly without the annoying spinning disk noise. I bought it mainly for transferring and storing thousands of family photos, and the transfer speed has been reliable and smooth. It is a great option for anyone who prefers keeping their files offline rather than using cloud storage. Simple to use, dependable, and excellent value for money.

Loved the quality, appears to be durable & eye catchy colour. Decent size for someone who has moderate data, speed is good enough, no heating problem, so overall good in functionality.

Cheap yet Effective way to store local files. A good Alternative of cloud storage. Absolutely steal deal. Nice compact size and good speed.

good

Great for the price

(Actualización de Octubre de 2025) Llevo usando este disco duro de 500 GB desde diciembre de 2024 para realizar copias de seguridad. Aunque no es el más rápido, para lo que lo utilizo, que es para hacer copias de seguridad de fotos, vídeos o documentos, me va perfecto. Después de casi un año usándolo diariamente (tengo configurada la copia de manera automática), su rendimiento sigue siendo estable, no noto nada raro, y su estado de salud está dentro de lo normal, comprobado con CrystalDiskInfo. Por lo que, a día de hoy, me sigue dando tranquilidad para usarlo para las copias de seguridad. Lo conectas, copias y listo (yo lo tengo conectado permanentemente). La velocidad típica de 100–120 MB/s es la normal en disco HDD, y considerando su precio, funcionamiento, bajo nivel de ruido y capacidad de 500 GB, creo que ofrece una excelente relación calidad-precio. 🎥En el vídeo se puede ver cómo es físicamente el disco duro y los resultados de las pruebas de velocidad (lectura y escritura) que le he realizado y que cumplen con las especificaciones del fabricante. ✅ 📌Lo que me ha gustado: 🔹Precio económico (me costó 28,79 €, ahora 31,99 €) 🔹Funcionamiento sencillo y tamaño no muy grande. 🔹Incluye cable USB 3.0 (es importante usar un puerto USB 3.0 para el mejor rendimiento). Se conecta a un puerto USB-A. ⚠️ Ten en cuenta: 🔸 Al ser un HDD evita golpes y no lo muevas mientras está funcionando. 🔸 No es ideal para trabajar con archivos grandes directamente desde él. 🔸💡Si quieres más velocidad por unos 10 € más, tienes otras opciones en Amazon, discos SSD con velocidades entre 4 y 5 veces más rápido. 🔍 En resumen, el UnionSine HDD no es un mal disco duro, pero si priorizas la velocidad un disco duro SSD puede ser una mejor opción por poco más. Gracias por leer mi valoración. Espero que te haya sido de utilidad. 😊
