    • Works great
Style: Portable HDD Capacity: 5TB
The lack of directions is a bit annoying but it is easy to use. You just plug it into your laptop and then find it's name in your 📂 section. I opted for the 5tb so I knew I had plenty of space for all my school work and the drive quality seems exceptional. I have seen others complaining about how slow it is and I have to disagree. It definitely takes some time to transfer several thousand files at once over but it definitely didn't take me a whole day to do it. And with it's size I've barely put a dent in it. I also like the size of the HD as it's not bulky and can sit perfectly on the corner of my laptop without being in the way. I also haven't noticed it over heating. It does a great job staying cool even if I leave it plugged in all night long or for a couple of days. My only complaint is it could of come with a longer cord. Also my acer laptop won't eject it even if all my programs are closed it give me an error saying it's still being used by something. It could be because of my one drive account but I'm not sure. I typically will just shut down my computer and then unplug the HD. ... show more

    • Perfect for Designers & Creatives – Fast, Reliable, and Stress-Free Backup
Style: Portable HDD Capacity: 2TB

As a graphic designer, I work with a lot of large files — PSDs, high-res images, Illustrator projects — and I needed something dependable to offload my work from my computer. The Seagate 2TB Portable Hard Drive has been exactly what I needed: simple to use, fast enough for daily backup, and roomy enough to store multiple client projects without slowing down my computer. Why I Got It: I was tired of my laptop running out of space, especially with the size of my design files. I needed external storage that wouldn’t break the bank but would still keep everything organized and accessible. This Seagate drive gave me that peace of mind and more. Design-Friendly Performance: It works seamlessly with both Windows and Mac. I use both depending on the project. The drive was instantly recognized, and I reformatted it for Time Machine on my MacBook without any issues. Transfers are smooth with the USB 3.0 — perfect for moving big Photoshop and Illustrator files without lag. Massive Storage for Creative Files: With 2TB, I’m storing client folders, final exports, stock graphics, video edits — you name it. It's organized my workflow and freed up space on my devices, which keeps everything running faster. 🧳 Portability + Protection: It’s slim, lightweight, and easy to carry to client meetings or work on-the-go. Plus, the 1-year Rescue Data Recovery Services included gives me an extra layer of protection, which I really appreciate as a creative professional — our work is too valuable to lose. If you’re a designer, photographer, or just someone with a ton of files, this hard drive is a must-have. It keeps my laptop light, my files safe, and my projects organized — all for a great price. Highly recommended! ... show more

Style: Portable HDD Capacity: 5TB
The Seagate Portable 5TB External Hard Drive is fantastic for backing up my movie collection. It offers plenty of space, and the read/write speeds are quick enough for smooth transfers.

Pros: ✅ Huge 5TB Capacity – Great for backups & media storage ✅ Fast Read/Write Speeds – Handles large files with ease ✅ Plug & Play – Works effortlessly with PC, Mac, PS4, and Xbox Cons: ❌ None so far! Final Thoughts: A great choice for those needing high-capacity external storage. Works well for backups, movies, and gaming—definitely recommend! 🎥🎮💻 ... show more

    • Good drive for the cost
Style: Portable HDD Capacity: 2TB
I got this to replace a dying backup drive, it was easy to hook up, easy to setup to Time Machine, and it works just fine. It’s a bit slow, so I wouldn’t recommend it for a gaming system, unless all you gonna do is backup with it, and the usb cable it came with is a little short.

    • Easy to use and very capable device.
Style: Expansion HDD Capacity: 8TB
This is an incredible drive. It was easy to set up and connect to my iMac. It occupies just a small space on my desktop and is very quiet. I use it as computer backup and, because of its speed, it's perfect as temporary expanded memory for my Photoshop projects.
