  • It does the job well
Capacity: 22TB Style: Expansion Desktop HDD
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. ... 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

  • Simple, high quality, long lasting
Capacity: 4TB Style: Portable HDD
I purchased one of these several years ago, and was pleasantly surprised to find that they sent me a case of 8 brand new SSDs, kept a few, sold a couple at about a 60% discount from the online price, gave a couple away as gifts, and their lifespan has been impressive, they've all performed beautifully the whole time I've had them. Instant access to files with no complex processes to follow, although the stock cable could be longer. ... 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

  • 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

  • Compact Storage or Backup with Large Capacity.
Capacity: 5TB Style: Portable HDD
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.

  • Huge Storage and Easy to Use
Capacity: 5TB Style: Portable HDD
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. ... show more

  • If you are looking for PS5 storage read this review
Capacity: 2TB Style: Portable HDD
Works great, solid product. If you are purchasing for the PS5, know that you CAN ONLY PLAY PS4 games DIRECTLY from this drive. You can STORE PS5 games on this all day long, but can only play PS5 games directly from the internal m2 memory. Again, you can transfer PS5 games to this drive to store but they have to be transferred back to the PS5 to play them. It is much faster than uninstalling and reinstalling games and you do retain your save files. PS4 games store and play directly from this external drive. If you'd like to increase your PS5 internal game space, look for M.2 SSD expansion. ... show more
