Seagate IronWolf 12TB NAS Internal Hard Drive HDD – CMR 3.5 Inch SATA 6Gb/s 7200 RPM 256MB Cache for RAID Network Attached Storage (ST12000VNZ008/ST12000VN0008)

I bought a 4TB Seagate Ironwolf drive to replace a WD drive I had that was giving errors in my UNRAID server. I have not bought a Seagate drive in a very long time. There was a period of time when Seagate was great, then a period of time when they were not so great. Anyway, I figured I would give Seagate a try again, especially since their drive was $15 cheaper than the same WD drive at the time. I received my drive and it was well packaged in protective packaging and inside a box. The drive had the same familiar footprint dimensions but was a shorter height which was interesting. Anyway, it didn't make a difference really. I removed my failing WD drive from the server, and then slotted this seagate drive in. I then started the server and once booted I assigned the drive to the correct slot in the menu and the server immediately began rebuilding the data on the new seagate drive. The drive had zero issues and zero errors on it from testing and rebuilding. It delivers good read/write speeds, but read/write speeds are really dependent upon many factors and what the server is doing at the time and so forth, so no detailed reports on that. The Seagate drive has been running 24/7 on my server for about a month now and not a single issue with it so far. The shorter height is interesting as it lets more air from the front facing fans pass between it and the drive above it, so that is a plus I suppose. If this drive holds up for 6+ months I will probably replace more of my server drives with Seagate drives. I have 2 other server drives coming on replacement time in near while, so I will be purchasing at least a couple more of these as they go on sale from time to time.I will need to compare the longevity of the Seagate drives with the WD drives. I've had good luck with WD up until about a year ago. Now, their drives do not seem to be of the quality that they once were. I get a lot of errors on some WD drives sooner than expected. Hopefully these Seagate drives fair better.Anyhow, so far so good.--------------------------------------------UPDATE 15AUG2025--------------------------------------------So, a 4TB WD RED PLUS drive in my server went bad. The drive is 4 month old. It started about a week ago with some Sector Reallocation errors, then more errors over the days... then hundreds of bad sectors. I couldn't write data to the drive anymore, then the server kicked out the drive and refuses to start it up. I pulled the drive and tested on my PC... yeah, the drive is going bad, and it is going bad fast. I formatted it, put it back in the server (to trick the server into thinking it was a new drive), it rebuilt the data (after about 10 hours or so), and all seemed fine. But, soon after (within hours), it started acting up again. Definitely a bad drive.I can read data from it, but writing to it is challenging as it triggers a cascade of sector errors. Had to call WD today and RMA the drive... now I have to pack it up and ship it at my expense to get a replacement. Honestly, it's probably not worth it. I do not want another new WD drive in my server. I'll probably put in on light duty on one of the kids PCs or something instead. WD's quality has fallen into the toilet, and this new drive I will get from them will probably be another bomb waiting to happen. You know sticking in a new replacement into the server and waiting 10 to 12 hours for the data to rebuild is not particularly fun.WD I am not impressed in the slightest. This is particularly bad since this was a BRAND NEW RED PLUS drive. I not long ago replaced another WD drive with a Seagate. A brand new WD Red Plus..... and sitting next to it is a 5 year old WD Blue purring away happily without complaint... WOW! What happened to WD?!?!?! I have a 7 year old WD Green (they don't even make them anymore) that still works fine... and a new RED Plus can't make it past 4 months. Amazing. I even have a WD Blue that is years and years old in my security camera DRV/NVR recording 24/7... never has an issue...WD used to make good product. They are garbage now in my opinion.So, guess what I ordered as a replacement for the RED PLUS? Yep, I ordered a Seagate Ironwolf... even though WD is giving me a replacement (which you have to wait weeks and weeks for), I am paying for another Seagate to replace it with. The Red Plus will never see the inside of my server as I do not need the aggravation.It might be a long long long time before I ever order another WD drive again. Not until they sort out their quality again. My advice is to stay away from WD drives.... it is hit and miss with them. It is like playing Russian roulette with your data.So, we are down to two players left in the HDD world; Seagate and Toshiba. But, for now I am happy with Seagate.

I have an array of IronWolf 8TB Drives in a Synology NAS, and a second array in a JBOD enclosure that serves as a target for nightly backups of the NAS. Both the NAS and the back-up array have the drives configured in RAID.The drives perform flawlessly. I think that the price is a very good value, considering the heavy duty construction dependable performance in a 24/7 task environment. I have several other sizes of Iron Wolf drives in other roles in my home that has two busy home offices. The IronWolf line is excellent. HIGHLY Recommended!

The Seagate IronWolf 8TB NAS Internal Hard Drive has become an integral part of my home server and smart home setup. Recently, I added two more of these drives to my existing 16-bay OMV NAS rack, bringing the total to eight. These drives play a crucial role in my system, where I use union filesystems to merge them into a single drive folder and implement SnapRAID for data protection against drive failures. Additionally, they're an essential component of my backup system. These drives have proven to be quiet, reliable, and excellent performers when it comes to file sharing across my network. They are my go-to choice for NAS setups, and I highly recommend them to anyone in need of dependable storage solutions.Pros:Reliable Storage (5/5): The Seagate IronWolf drives have consistently delivered reliability and peace of mind for my data storage needs.Quiet Operation (5/5): Despite their powerful performance, these drives operate quietly, ensuring a pleasant environment in my home server setup.Great File Sharing Performance (5/5): These drives excel in file sharing performance across my network, providing fast and consistent access to data.Conclusion:In conclusion, the Seagate IronWolf 8TB NAS Internal Hard Drive is a fantastic choice for anyone looking to build a reliable and efficient NAS system. They have seamlessly integrated into my OMV NAS rack, where I rely on them for data consolidation and protection. These drives offer quiet operation, great file sharing performance, and above all, the trustworthiness that is essential for NAS setups. Whether you're a seasoned enthusiast or a newcomer to network-attached storage, these drives come highly recommended for their quality and performance.

I've got 4 of these as data drives in a NAS array, running 24/7 with a light workload, and have so far had no SMART errors or bad sectors. With my setup (tightly packed drives in an enclosure, noctura 120mm fan running at 100% speed) in 21 celcius ambient temps, they run about 32 c idle, and 40 c under load.I've read some mixed reviews about their reliability on a large scale in a datacenter setting, but for my needs as a homelab NAS drive, they are more than adequate for a better price than some other comparable drives from other manufacturers. I specifically bought due to their CMR, 7200 rpm, and cache size.They are definitely noisier than a normal consumer HDD, but not nearly as bad as I thought they'd be or I'd been led to believe. Activity is very audible as a low rumble.Edit: totally forgot that I did have one drive that was dead on arrival, but with Amazon’s return process was no problem to get it replaced.
