    • EXOS are noisy, but last
Capacity: 18 TB
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. ... show more

    • It makes less noise than my fans.
Capacity: 14 TB
Very good purchase I only needed 4TB and I have 12TB usable. Manufacturing date a few months ago, I didn't expect it to be so new. It is fast and the start may be the only noisy thing, the rest is silent. I recommend the seller QuickDealStore. Double box (original) + amazon. International delivery. I updated the firmware following the manufacturer's instructions, everything went well. ... show more

    • Good product, good service
Capacity: 24TB
I have ordered a number of Seagate drives from QuickDealStores and product has always been as-ordered and in good working order -- even though they are not part of Prime Shipping, so a few days extra wait.

    • Great discs at a great price.
Capacity: 8 TB
Using four of the 8GB models in a zfs NAS build. Drives arrived well packed and simply wrapped in ESD bags. All four are running smoothly. Only complaint is I can occasionally hear the discs from across the room if nothing else is running.

    • Failed after 6 months - "fatal device hardware error" - not satisfied with warranty
Capacity: 16 TB
Purchased in November 2023 this Seagate EXOS 16TB drive failed after light use as an external backup drive connected via USB 3.2 cable to my lightly used Dell XPS 8960 computer where for maybe four hours a day I do emails and spend time online and process and post my own photographs. In other words I am a home user not generating much data. The drive did a few full backups and then incremental daily backups since late November. For redundancy I used a second 16 TB drive on alternative weeks, a Toshiba X300, that is still working fine. So my Seagate EXOS only worked for three months actual work, doing about 10 minutes backup per day. Last week I was most unhappy when the Seagate stopped doing backups. Windows Computer Management > Disk Storage reported "fatal device hardware error" and could not access the drive... could not read the drive or write to the drive. Last Thursday six days ago I went to the Seagate website warranty page requesting a replacement and today, Wednesday, I received a replacement on my front steps. Very nice, very efficient. However, one huge problem. Seagate is requiring me to return the bad drive without removing confidential data. I just now had an online chat with a very polite support person telling them the drive contains a lot of confidential data and I want to make sure the data cannot be read. I explained it is impossible to use software to erase data on a drive that cannot be read and that I want to drill a hole through the disk to prevent anyone from accessing it. While I cannot access the drive on my computer, a technically skilled person might be able to access it using more advanced techniques or just fixing the hardware error. The person responded saying that drilling the hole will void my warranty. They added that Seagate's procedures and protocols will absolutely prevent anyone from seeing my data. I responded saying I know Seagate to be an honorable and reputable company, but that I know perfectly well procedures and protocols are not always followed. So... I am not at all satisfied with Seagate's warranty procedures. Customers should be allowed to obtain warranty replacement on a failed drive that the customer disables to prevent any access to confidential data. They send the bad drive in purely to provide proof of drive failure. ... show more

    • About the Sound
Capacity: 14TB
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.)) ... show more

    • Noisy Good Drive

The drive is good and the price is right. It has enough storage to fit my pictures and home videos. The only complain I have is that is is very noisy.

    • Decent Value, A Bit Noisy
Capacity: 14 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.
