SeagateIronWolf Pro, 20 TB, Enterprise NAS Internal HDD –CMR 3.5 Inch, SATA 6 Gb/s, 7,200 RPM, 256 MB Cache for RAID Network Attached Storage (ST20000NT001)

This is my third Seagate IronWolf internal NAS hard drive and the largest drive I've purchased to date. It was very easy to set up, connected immediately and has worked flawlessly since I installed it. The read/write times are quite decent as far as HDD drives go, especially at this size of storage. I am able to transfer large batches of files reliably in a reasonable amount of time without any issues.I have two of these drives installed in my studio workstation and one in an external dock. All of them have worked equally well, regardless of how they're connected. They are well designed and reliable, so they have become my go-to drives for file storage and backups. I trust them for short term storage, as well as backing up and archiving all of artwork, photos, videos, and studio documents long term. I also really appreciate the large storage space at this price point.I'm very pleased with my Seagate IronWolf internal NAS hard drives and plan to purchase another of these 12 GB drives in the near future for additional backups. I definitely recommend them to anyone looking for a large, reliable HDD drive at a reasonable price point!

I bought two 8 TB Seagate Iron Wolf NAS HDDs to mount in a new Synology DS224+. The drives were well packed, easy to prep for installation, and went into the DS224+ with no trouble. An hour after I opened the box the DS224+ was on our network loading installation data. The drives have never hiccupped, lost a bit or a byte, made excessive noise, or been the source of any problem. I see and read the reviews by other users who had different experiences. Those unhappy experiences are very different than mine. Our Synology NAS devices with Iron Wolf 8 TB HDDs store and stream music and videos, and maintain photos and important correspondence. They've been trouble-free for 14 months of usage. They run at 91 and 95 degrees F, connected to our home LAN.I would recommend these Iron Wolf HDDs to anyone building or acquiring a home NAS.

I bought two of these for my new Synology NAS and they are working perfectly. I've had my old ReadyNAS box for a LONG time; it is noisy, slow, and hot. The combination of the Synology DS224+ and these drives has been much quieter, faster, and cooler. I store all my video projects (along with a LOT of other stuff) on this system. When I am copying files, I can hear the drives a little, but it is not bad at all. So far, I love the combination.Recommended.

Seagate Iron Wolf Pro 20TB has a large capacity, easy setup and format, and very quiet.I'm using it as a data backup system and I backed up my entire desktop system with 4 various HD and NVME disks and it filled up just over 25% of this disk.I did have a problem with this order as I received the first shipment only to find that the box label had the right info but the disk inside was a Seagate Barracuda 256GB HD. Certainly a return scam. But Amazon reordered it and the second order was right.I HIGHLY recommend this 20TB Disk, especially when it was the same price as a 16TB

I ordered two of these drives (ST12000NT001). They work very well and are very quiet in a be quiet 802. They do not have the 5-second click that I read WD Black drives have.Unfortunately, one of them died (post-return date). I have spent many hours working with Seagate to get a replacement drive. They have kept trying to send me an IronWolf (non-Pro) drive (ST12000VN0008). I received the first drive and was ready to send it back, but they tried to send another non-Pro drive.Apparently, they are out of stock, so their system wants to downgrade my drive. I even mentioned that Amazon has them in stock if they want to buy one for me. :)It is a great drive when it works, but the return system is rather lacking which can play into the decision to purchase future drives. The people I have spoken with via the support bot have been very nice. The down side is that the system wants to give me a lesser model. If you need to return yours, watch carefully on what the replacement is.Report Card (if Amazon allowed split scores):- Drive: A (when it works)- Support staff: A (very polite and helpful but a bit uninformed by Seagate on how to handle odd cases)- Support system: F (Seagate *really* needs to fix its process, so the correct drive is sent in the first place)Update (2024/2/29): Seagate still cannot find a replacement IronWolf Pro drive to send me. I have spent hours on chat with different people. The last two times I contacted Seagate, I have received the "check back in 48 business hours" after being in a chat for more than two hours. The killer is that they have that unit available on their own website for sale. I have given the support people high ratings each time, yet the "Would you recommend Seagate?" question keeps dropping. I am now dropping my rating here from three to two stars.Update (2024/4/1): It continues. Seagate sent me another incorrect drive. I am currently speaking with support. The best they can do is find an NE001 model even though they have the NT001 models in stock at Amazon and Seagate. They say they can only provide Factory Certified and not new drives under warranty. However, they had plenty of time to refurbish the drive I sent them. I know they cannot just send me back the same drive, but I am very frustrated. Knocking the review down to one star. I doubt I will buy another Seagate drive at this point. It is too much hassle.Update (2024/6/19): A bunch more back and forth has happened. I received another incorrect drive. There was confusion on the status of my RMA. Some thought it was finished probably due to how long the information in the ticket was. Finally, I got in touch with a support person that was able to find the right group above her to handle it. They told me, via her, to keep the incorrect drive, and they would send a new drive. Well, it was another refurbished drive, which is what I expected at the beginning of this, yet it was the correct drive. Checking the warranty on the drive showed it to be only a few months, so I had to contact support again to rectify it. At first, they bumped it to three years. He had me check their site to verify it was correct but was quick to fix it to five years. Seagate should make their own drives easier to differentiate if even their own support can be confused. My head hurts. :)At long last, I have the correct replacement drive. It only took 4 months. Ugh!Update (2024/7/5): Three weeks. That is how long the replacement drive lasted before it crashed.Update (2024/7/30): Not as much difficulty this time, although spent hours on it, another replacement drive is on its way.Update (2024/8/5): The replacement drive was DOA. Of course.
