louder read/write noise than other drives, however I have about 8 of these running 24/7 for the past few years and only had one with an issue (replaced by seller, box looked damaged during shipment). great cost per TB, and is sufficient for media and game development.

would love SSD to get to this cost range per TB.

Having not upgraded my storage for at least 10 years, it's hilarious to see entire drives' worth of data fitting onto one single drive with so much more room to spare. These drives are a bit louder when in use compared to the older, slower drives I've replaced, but that's fine.

Stay away from the 18TBs

Reviewed in the United States on March 17, 2024

Capacity: 20 TBVerified Purchase

I have purchased numerous Seagate drives, internal and external, over the years, but this review is for the 18TB drives I bought on Amazon. I have purchased 3 of the 18s. The first one started to fail shortly after I bought it and I had to hustle to save data before it became unusable. The second one disappeared to large folders filled with important files. I didn't even get a notification until I noticed they were missing and scanned the drive. Recovery software could see the lost files, but only recovered a fraction of them. Later, while removing the drive from the computer, the plastic SATA clip on the back snapped off, rendering the drive unusable. I tried to transfer the piece from the first bad drive to it to see if I could boot it, but it didn't work. I bought the third 18TB in Nov 2023. Now, just 4 months later, it is starting to fail. I have to scramble once again to get my files off of it while I still can. It's strange because I have 10 Seagate HDDs in my computer, and I can't remember the last time I had a drive die on me before I could Lifecycle Replace it. But I'm inclined to think there is something wrong with the 18s. I didn't return my drives to Seagate because I don't want to share whatever data can be recovered. So I'll just eat the loss, about $1000 for the 3 drives. The next time a Seagate lets me down, I'll be switching to WD.

About the Sound

Reviewed in the United States on November 17, 2023

Capacity: 14TBVerified Purchase

So I don’t write too many reviews, but I wanted to put this together for people who are as confused as I was about whether or not these drives are loud.
Before I settled on these, I read tons of reviews on Newegg and Amazon and it seemed like a pretty even split between people who think these drives are horrendously loud, and people who think they are silent as the grave.
The short answer seems to be, they are both.
The key is how they’re being used.
In my experience, these drives are silent until a couple of seconds into a large data transfer. After that, they start to make some noise, and it is significant. I wouldn’t want to listen to it for a long time. However, in my use case, (a personal home media server that only I use) I never reach the maximum speed of the drives (around 250mb per second) unless I am transferring whole shows onto the drive, or exporting them to an external device, and in that case, the transfers do not last long. Also, I am not seated next to the computer when tranferring large files so the sound is quieter from a short distance.
My advice when purchasing these drives is to think about your use case. Mainly, how often will you need to move files that are bigger than just a couple gigabytes? Because that is when the louder, more concerning noises will occur.
Also, consider setting up your pc so that the drives never disengage or “spin down” once the pc is on. There is a delay of several seconds before you can access files and a lot of noise when the drives first spin up before they settle into silent operation. (Personally, I like the sound they make when they spin up, but I wouldn’t want them doing that all the time. It’s bad for them. ((I know that is contested, but I’m saying it anyway, since I think the people on the other side of that argument are wrong.))

It is a hard drive, nothing more, nothing less.

Reviewed in Canada on August 2, 2021

Verified Purchase

If there is one thing to say about this hard drive is the sustained transfer rate of 261 MB/s rivals early generation flash drives. It is hard to find a single drive configuration using the SATA interface that would be faster. If you want and can afford the SAS interface then there is a similar Seagate hard drive that recently held the world's speed record for sustained data transfer rate. The other defining characteristic about this drive is its storage capability coupled with the fact that it is an enterprise rated drive. That will give you 24/7 operation for a mean time between failure rate of 2.5 million hours. I am a gamer and with the current direction that games are going in, of a typical size of 50 GB or more, fast storage is all important. Installation is simple like any other current hard drive and this drive can be configured as your primary operating system hard drive or backup data drive. It is a little on the expensive side for a single hard drive but when weighed against it performance and size it is a good value for the money.

A bit noisy, but honestly barely noticeable in desktop PC. And huge storage. Firmware upgrade is pain in the ass, but its same for all HDDs (and probably unneeded). And great value for such huge storage capacity.
