    • Good drive
Capacity: 2TB Style: Portable HDD
worked great out of box... Small issue of going from win10 to win11 tho. Win10 was drag /drop, no problems. When linked on win11, file folders were not found. Solved issue: create the folders on Win11 first, then drag /drop from win10 to those folders....all good Speed good for it's type, 2TB is plenty BU for me. ... show more

    • Perfect
Capacity: 4TB Style: Portable HDD
I picked up this 4TB hard drive with pretty simple expectations: I wanted something that would work, store a lot of data, and not give me any headaches. After using it for a while, I can say confidently that it delivers exactly that. Performance & Reliability: Right out of the box, the drive worked flawlessly. Setup was quick—pretty much plug-and-play—and my system recognized it immediately. Transfer speeds were solid and consistent, not blazing-fast like an SSD of course, but exactly what you expect from a dependable HDD. Whether I was moving large video files or backing up a ton of photos, it handled everything without stuttering, freezing, or randomly disconnecting. Noise & Heat: The drive runs quietly, with only a faint hum during heavier transfers. It also stays at a stable temperature; even after extended use, it never ran hot or worried me. For anyone planning to keep it inside a PC case or use it as an external backup unit, this is definitely a plus. Build Quality: The construction feels sturdy and well-made. Nothing cheap or flimsy about it. The ports are secure, the casing feels solid, and overall it gives the impression of something built to last. For a drive of this capacity, that peace of mind matters. Capacity & Use Case: 4TB is a sweet spot for a lot of people—it’s plenty of room for games, media collections, backups, or general long-term storage. I’ve already loaded it with a substantial amount of data, and it performs just as smoothly at higher fill levels as it did when empty. Overall: This is one of those purchases that doesn’t try to impress with bells and whistles—it just works. And honestly, that’s exactly what I wanted. If you're looking for a straightforward, reliable 4TB hard drive that performs well and doesn’t cause headaches, this one is a solid choice. I’d absolutely buy it again. ... show more

    • It works well for me, for now atl.
Capacity: 24TB Style: Expansion Desktop HDD
Great, for local storage either networked or not. Recommend replacing their garbage usb cable that comes with it (cable matters makes a good one). Pretty silent under low operation, speed is usb. Lifespan with seagate is hit or miss. I’ve had drives from them last a couple days and I’ve had drives last nearly a decade so hardware gambling. Wouldn’t recommend anything sensitive going on it, if it dies it’s gone. I use mine paired with a local caching machine for windows and steam updates. (Games too) it runs on the network via that “server” and as I learned when dealing with mechanical drives, don’t put stuff on it you can’t afford to lose. Was getting 460ish MB/s average read and 390ish MB/s write with your peaks and dips associated with HDD madness. ... show more

    • Ton of space, reasonable price, occasional noise
Capacity: 22TB Style: Expansion Desktop HDD
I recently picked up a 22TB external hard drive, and so far it’s been a great value for amount of storage you get. The capacity is huge for the price, which makes it appealing option if you need a lot of space without spending a fortune. Physically, it’s a typical external drive—nothing oversized or bulky—so it fits easily on a desk or shelf. One thing to note, though: it can get a bit loud at times. I wouldn’t recommend keeping it running full‑time in a quiet space like a bedroom office unless you don’t mind some background noise. My main use is offsite backups, so I only plug it in for short periods. Because of that, it’s too early to say much about long‑term reliability. Performance‑wise, it’s not the fastest drive out there, but it’s perfectly adequate for backup tasks and general storage. Overall, if you need a ton of space at a reasonable price and don’t mind occasional noise, it’s a strong choice. ... show more

    • Good for a NAS build...
Capacity: 20TB Style: Expansion Desktop HDD
The external hard drive enclosure is slightly bigger than the actual hard drive itself. In my experience it has an okay speed. Not the fastest drive that I've used. The USB port is a normal usb-a 3.0 port so no usb-c. The power source has multiple adapters for people who would use it for their travels so no matter what kind of power outlet it present you should be okay. The design of the external case has openings to vent the heat coming from the actual hard drive inside. In terms of security, the drive is held in my rubber pads within the external enclosure that are surrounded by plastic tabs that hold it in. The external hard drive is a good choice to use for a NAS build if you are comfortable shucking the external case. The price is competitive when compared to a normal NAS internal drive. If you choose to go that route bear in mind that shucking the drive comes at the risk of voiding the warranty. Overall it's decent and has been running well on my NAS. The okay speed on the drive is the limiting factor which is why it's 4 out of 5 stars. Lastly the actual enclosure itself will still run other old drives if the ribbon cable and board aren't damaged during the shucking process. Any old 3.5 internal drives would work perfectly to recycle and not throw out the remaining hardware. ... show more
