Seagate IronWolf 4TB NAS Internal Hard Drive CMR 3.5 Inch SATA 6Gb/s 5400 RPM 64MB Cache for RAID Network Attached Storage Rescue Services (ST4000VNZ06/006)

Unlike many others here, I am running an UNRAID server rather than a Synology or QNAP NAS. Perhaps that's why my mileage has varied, such that I have had no failures whatsoever and my server is 100% uptime.I am running (2) 24TB Ironwolf Pro for parity, (8) 12TB Ironwolf Pro for the array and (3) 4TB Samsung EVO NVMe for the cache pools. This all runs on an Intel i9 14th Gen Processor, Gigabyte Aorus Elite motherboard, 128GB Ram and 16-Bay Tower.My workload consists of 24/7 reads and writes including, at times, up to a simultaneous 6-8 4K video streams. The drives never spin down and are active 100% of the time.I've been running this setup for a little over a year now and have had not a single error with parity checks running twice a month and SMART monitoring 24/7. With that said, I think a lot of what makes a drive last is the hardware connected to it and the workload associated with it. I don't expect these to last forever, though. I've been using Seagate drives for over 20 years and I can usually expect 5-8 years before they fail (with constant use). All in all, I'm very happy with these drives and carry very high expectations for the future.

I have both the 16t and the 20t. I wanted two 20t HHDs but the is what was available. They both work fine but the 16t is very noisy. Not enough to bother you during the day but noisy enough to interfere with sleep if it is in the same room as you. The 20t sounds like any other internal drive.In Europe Seagate has been caught selling used drives as new. To make sure these are new, when you get em make sure the warranty is still valid and test the drive with software like ScanDiskInfo. Scan Disk Info wont fix anything, all it does is diagnostics and it is free. It will tell you how many times it has been turned on and off, how many hours it has been running, how many times it has been written too and read from and if there are any bad sectors and much much more. It is a wonderful utility for monitoring the health of your Drives.Mine are both new and unused.

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!

The Seagate IronWolf 8TB NAS Internal Hard Drive HDD is a GREAT option for your Synology NAS. While it appears that Synology has recently decided to only recommend their own HDDs for support reasons, Seagate IronWolf remains an affordable option for users.I purchased this to expand my existing data pool and both installation and integration were a snap. It took about two days for the system to integrate the drive and it's working great!Thank you Seagate and Amazon for keeping these drives affordable!

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.
