The Seagate IronWolf 12TB is a high-capacity internal hard disk drive designed specifically for network attached storage (NAS) systems. This 3.5 inch (8.89 cm) HDD features a rotational speed of 7200 revolutions per minute and utilizes conventional magnetic recording (CMR) technology for consistent performance in multi-drive NAS environments. With 12 terabytes (12000 gigabytes) of storage capacity, this drive provides substantial space for data-intensive applications, media libraries, and backup solutions. The drive includes a 256 megabyte cache buffer to enhance data transfer efficiency and supports SATA 6 gigabit per second interface for reliable connectivity. Engineered for 24/7 operation, the IronWolf series is optimized for NAS systems with one to eight bays, offering workload rates suitable for small business and home office environments. The drive incorporates AgileArray technology with dual-plane balance and rotational vibration sensors to maintain stability in multi-drive configurations. This model includes Seagate's IronWolf Health Management system, which works with compatible NAS systems to provide preventative monitoring and data recovery options. The product comes with a data rescue service that offers data recovery assistance in case of drive failure. Measuring approximately 14.7 cm in length, 10.2 cm in width, and 2.6 cm in height, the drive maintains standard 3.5 inch form factor dimensions. With a weight of approximately 720 grams, it provides substantial storage in a compact package. The drive operates within a temperature range of 0°C to 60°C during use and can withstand non-operating temperatures from -40°C to 70°C. Designed for reliability in always-on environments, this hard drive offers a balance of capacity, performance, and durability for NAS applications requiring substantial storage solutions.

I bought two base Asustor NAS devices and added 2x 12TByte Seagate IronWolf drives, and 2x 1TByte SSDs, with 2x 500GB NVMe SSDs to provide Network<===>Drive caching and high speed local access supporting offsite cloned support.The 2x 10Gbit ethernet ports and 2x 2.5Gbit ethernet ports can provide 20Gbit local aggregated support. The CPU is as one would expect for the price point but the 2x 10Gbit ethernet ports are exceptional value.So my vital signs are much improved and I recommend you do likewise.

A great drive for the cost. Approximately $35 per TB. The drive is a nice quiet one to sit next to while you have lots of data to copy to it. It takes approximately 1/2 day - a full day to copy it full. A 2 TB folder takes approximately 2-3 hours. Timing I guess depends on files, more than totals though as every time you copy a new file/folder it pre-makes the room for it’s storage. If you only had a few large files though, thus 500GB+ each they’ll copy much quicker than if you had say 2000 files in one copy task.Once your files are on this drive too, I’ve noticed that when you access them they load ready for you very quick. After all it’s supposed to be a drive for NAS units, but works excellent on it’s own. You should have no trouble RAIDing if you like. I’ve ... MoreA great drive for the cost.

I’ve always maintained that your data is best backed up as 3 backups - 2 Local - different drives and 1 offsite. If or when one of your drives comes to its knees, you at least know you’ve still got a workable backup to buy a replacement and re-copy your data safely. Hope this helps.

I bought 3 of these after my Drobo passed away and moved to Synology. I'm only giving thoughts on the sound. These things won't stop making noise.

The fan was obnoxious, but never heard the drives.With the Synology, the drives are constantly making noise. It's non-stop. I thought it was just because such a big backup was happening.

I bought 9 of these in 2017 for my SOHO Synology NAS. My wife and I have a small consulting business. We use the NAS for backing up the computers, intranet, email, and other typical server uses including a Plex server. Of the nine drives I have had only one failure. It occurred almost 3 years in, and was covered by Seagate warranty. Because the NAS is set up with two drive failure tolerant Synology Hybrid RAID we did not lose any data. Seagate had a warranty replacement drive back to me in 4 working days. Overall I've been very happy with these. They work well, and they're reliable enough for home use without the cost associated with an enterprise-class drive.
Seem to be good high-capacity drives for my DiskStation NAS. Strangely though, I bought two of these 12TB disks at the same time from B&H and yet they have slightly different part numbers and firmware versions. Since they're in the same RAID mirror, I thought they ought to be identical. When I investigated using Seagate's tools, I was even more surprised that it claims they have different numbers of physical platters, yet the same total capacity. But they're working fine so far.
Great hard drive, not exactly what I wanted. I only learned after I received the drive that it was designed for use in a data center. This however has not caused me any issues the drive installed easily and formatted with zero issues. I would recommend this drive to anyone who needs large capacity storage at a decent price.
Fast as a SATA HDD can get. A lot of space, 11.1TB after format as normal. I have owned many Seagate HDDs over the years, they still work. I end up upgrading for the convenance of having less HDDs. I have two of these in a Synology NAS in mirror RAID. Upgraded two 6TB. No trouble and have a piece of mind that my data is safe. These are CMR type HDDs, energy efficient, minimum heat production, transfers data above 150MB/s when in PC and avg 110MBs in NAS over GB ethernet. transfer rates very by PC and type of file being transferred.
After purchasing and send back 2 fake Ironwolf 12TB hard drives from eBay I learn my lesson so I went to Scan and purchase my 4 genuine Ironwolf 12TB Seagate ST12000VN0008 IronWolf NAS 3.5" HDD. drives Plus 1 genuine drive my son brought me from America and place them on my Synology 5 drive Station and load them with no problems at all as my son says buy nice or pay twice. I highly recommend Scan Computers you know you purchase the real thing whatever you buy 10 out of 10.
I was surprised how quickly the prior 4TB WD Reds filled up. (it all those backups and a lifetime of photos). These didn't appear on the approved drive list for my box, but the 10TBs were. Much to my delight, the 12's went in with no problem. I replaced one at a time. Since I'm using RAID 1, my NAS immediately recognized the new drive and spent the next day and a half synchronizing. When it was done, I put the other new IronWolf in. Same scenario. When the sync was complete everything was as it should be, except bigger and faster! Great deal on these B&H helped too.
I haven't purchased Seagate drives for many years, due to a failure, but decided to give them another go. They seem to have upped their game and I can't fault them at all as they just seem to keep going. I bought two of these 12TB drives to add to my NAS which already had 2x 12TB ironwolf nas drives installed which I bought 2 years ago. They went in with no issues and scans came back with no bad sectors detected.These are my new go to drives now when upping the capacity of my NAS drives as they've never let me down so far and the speed is really quick.
