I absolutely love this external hard drive. The fact that it works without needing external power is a huge plus — just plug it in and go. It’s lightweight and compact, making it easy to carry anywhere, whether I’m traveling or just moving between home and office. The build quality feels solid and durable, and it performs exactly as expected. Fast file transfers, plenty of space, and no setup headaches. Perfect for backups, storing media, or transporting large files. Highly recommended if you need reliable storage on the go. ... show more

    • Great drive
Style: Portable HDD Capacity: 5TB Color: PORTABLE
NO PROBLEMS AT ALL. ALL I COULD WANT IN A 5 TB HARD DRIVE. PLUG AND PLAY. KIND OF SLOW BUT EXPECTED THAT OUT OF A PORTABLE HARD DRIVE.

    • Good buy
Style: Portable HDD Capacity: 2TB Color: PORTABLE
Great hard robe. Lots of space, easy to use. This thing is solid also, been dropped plenty of times. Doesn’t seem to get hot or anything. Design is simple, it’s not too big or small.

    • Very good for the price
Style: Portable HDD Capacity: 2TB Color: PORTABLE
It's small, compact and easy to transport. Works well and doesn't require any installation. Upload and download speeds are great. Would get 5 stars but it is not optimized for Xbox Series S so not all games can be played directly from the hard drive. Games can still be stored but need to be transferred over to the device's internal storage to be playable. ... show more

    • Reliable and Spacious Storage Solution for Backups
Style: Expansion Desktop HDD Capacity: 8TB Color: DESKTOP
I recently purchased the Seagate Expansion 8TB External Hard Drive (STKP8000400) to back up my growing collection of photos, videos, and documents, and I’m very satisfied with its performance. Setting up the drive was truly plug-and-play—just connect it through USB 3.0 and it’s instantly recognized by my computer without any extra steps. The transfer speeds are excellent, so moving large files takes far less time than with my older drives. The 8TB capacity means I have more than enough space for my current needs and plenty of room to grow. The compact design fits neatly on my desk, and it runs quietly even during long backup sessions. Having Rescue Data Recovery Services included adds extra peace of mind in case something ever goes wrong. Overall, this Seagate external hard drive is a fantastic choice for anyone needing a large, reliable backup drive that’s simple to use and trustworthy. ... show more

    • Plenty of Room for Photo and Video Backups
Style: Portable HDD Capacity: 4TB Color: PORTABLE
I still remember the day I bought my first computer with a 40 MB hard drive. It was the early 1990s and truly thought I’d never outgrow that much “capacity.” Thirty-five years later and we’re talking terabytes, and just like money, it’s never too much. I bought this Seagate 4TB external drive to backup all the photos and videos I shoot with my iPhone, and even though I will outgrow it in a year or two, I’ll just get another one when this one is full (I want to save the thousands of pics and vids I have). I was fortunate to pick it up as a Prime offer, so I got a sweet deal. Installation was super easy and got it connected in a matter of minutes. It’s super fast, too, so I can use it just as I do the hard drive. Thank you for reading! 😊👍🏻 ... show more

    • Reliable Enough to Buy Twice
Style: Portable HDD Capacity: 1TB Color: PORTABLE
I've bought this Seagate HDD twice—once for myself to offload large files and run The Sims 4 (with plenty of mods), and again for my mom for similar use. It's durable, performs consistently, and the price stayed reasonable both times, even with a year between purchases. It doesn't overheat, even while running a heavily customized game, and keeps pace without issue. Solid quality for the price. I'd recommend it if you need a reliable external hard drive. ... show more
