Good price and good option for high-cap storage
This drive operates reliably and performs as expected. Deployment was straightforward, making it a solid option for anyone needing high-capacity storage at a reasonable cost. The speed and durability have been more than sufficient for my daily use so far.

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.

What a pain!!! Not worth it! Avoid at all cost!!
Hot garbage! Yeah sure it was cheaper and had more storage space than the competitors but I should’ve just bought other brands. Less than a month it just stopped working and started beeping….meaning hardware failure. Customer service is all bots then “human” via chat. I would be better off just burning my device to get anything. Slow to respond asking questions I literally told the answers in the initial what is wrong today. Asked if dropped recently. Ok if that’s your go to question maybe make it so it doesn’t stop working if it was bumped or dropped once. Other brands don’t seem to have that issue maybe put in better casing. Just a thought. I will send away and hope for the best and see what I get 30-45 business days from the day they receive. Update 1: When I setup the recovery I was given a choice to receive a hard drive with any recovered data (size of hard drive matches size of the recovered data) and either a replacement hard drive of one you purchased or the guts of your old drive which will cost you import fee and not have the casing. So far I have an update that they received my device but so far haven’t started to scan to recover data. I received my replacement hard drive that didn’t come in a box as if sold in the store and the outside of the box said refurbished. So basically you pay for full price new item it crashes you may get your data recovered or not but get a refurbished item replacement which typically costs less. I tried to return refurbished one because I paid full price for a new one and they said because it’s over 30 days (only because it took awhile for them to mail me my replacement so over 30 days maybe by a week or two) they won’t accept return per Amazon policy and take it up with the manufacturer directly…which I will but after I see if they recover any data I wouldn’t want to tempt them to “attempt and not be able to recover anything “…this is frustrating… Update 2: Got notice about 60 days or so after sending away the device that no data was recovered…shocking I know. It gets worse so I was able to start piecing my life back together slowly using recovery software on my other hard drives to recover some of the data I had moved to this product and then boom the replacement (a refurbished product) boom just crashed and died. This now is the third Seagate device I owned that crashed and died in my life, never had WD crash. I am asking for a refund from customer service at the Seagate and got asked to show proof of purchase and said I was eligible for refund and that they were processing it to then quickly say to rebuild your confidence in our product can I interest you in a new build? Apparently it’s sorry for your frustration twice but hey give us another chance to prove you right about us….I asked to talk to the supervisor as maybe they have authority for a refund and got the same run around. Ugh!!! So now gotta send it away to get a replacement that probably will die again. Take it from me don’t buy it!!

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.

HDDの値上げの情報を知ったので2025年11月時点に無理をして57千円台の時に購入。2026年2月時点で94千円に値上がりしていて良い買い物が出来たと思っています。

What i like about this HDD is the stable transfer speed with power supply unlike other that are unstable transfer speed. Got few TB of data transferred at ease. Only thing that might be a down side is the sound created might be a nuisance but overall it works very well for my heavy data. Will be back if data exceed again!

3.1,ya da 3.2 olmaması dezavantaj gibi dursada depolama yapacaklar için çok gerekli özellikler değil elbette bu durumda fiyata pozitif yansımış.

Use it as a long term storage
