It does the job well
I have several smaller hard drives I use to store photos and old files but they are getting old and it is hard to organize files, especially photos across several drives so I was in the market for a large hard drive to better organize my old files. I opted for the Seagate 22TB drive because of its' size and, for the size of the drive, it was relatively inexpensive compared to other options. Things I like about the drive: 1) It has a large capacity but is relatively small compared to my other external drives; 2) it is plug and play. I have some drives my system has a hard time identifying sometimes but there are no issues with this drive; 3) everything works out of the box. I have had no issues so far; 4) I use it on 3 systems and it works well on all 3 systems and is easy to move from one to the other. It is not my fastest drive. have a portable Sandisk SSD that is faster but it has not been a problem. You can hear it working but it is not annoying. Overall I am very pleased with the Seagate Drive.

Ton of space, reasonable price, occasional noise
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.

Perfect
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.

Compact Storage or Backup with Large Capacity.
The backup capacity is extraordinary for the price. Top quality and very quiet, this small unit functions fast and gives tremendous storage. Cable length is more than adequate and the unit is compact and stackable. I liked my first one so much, I purchased another.

Good for a NAS build...
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.

It works well for me, for now atl.
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.

One of those products that feels worth the money
I bought this external hard drive a little while ago, and I have to say it’s been a solid purchase. The first thing I noticed was how sturdy and well-made it feels—no cheap materials or flimsy parts. It does exactly what it’s supposed to do, and it’s been reliable every time I’ve used it. Setup was straightforward, and I didn’t have to spend a ton of time figuring things out. That’s a big plus for me because I like products that just work without a lot of hassle. Performance-wise, it’s been fast, consistent and dependable. I haven’t run into any issues, and it’s held up well even with regular use. The design is simple but practical, and slim which makes it perfect for transport. If I had to point out one downside, it would be that the price feels a little high compared to similar options. But honestly, the quality makes up for it—I’d rather pay a bit more for something that lasts than save a few bucks and end up replacing it sooner.

Huge Storage and Easy to Use
This Seagate 5TB portable drive is exactly what I needed for backups and extra storage. Setup was plug-and-play on both PC and Mac, and it works seamlessly with my PS4 and Xbox as well. Transfer speeds over USB 3.0 are fast for large files, and the drive is quiet and doesn’t get hot during use. The included 1-year Rescue Service is a nice bonus for peace of mind. Great value for 5TB of portable storage.
