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. It's absurd; comical if it didn't end up sorta stressful.With my Drobo, it sat in the TV agenda. 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. (due to having to back everything back up). Nope. they won't stop.Went over it with Synology and it's definitely the drives and their inherent noise.I don't know if I can move it to another room due to our home. I wish I knew of a hard drive that was quieter for my situation (Synology 1522+).It's only been a month, and I deeply ... MoreI bought 3 of these after my Drobo passed away and moved to Synology.

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.

What all can you really say about them? They're spinning drives and they're big! Definitely worth the money over the 5200rpm drives and a good cost saving point compared to SSD for big/long term storage. SSDs would be great, but for the storage I wanted it would be way too expensive. I bought a 4 pack of these for a RAID 5 configuration, which is giving me 15.69TB of storage. Actual capacity of these drives are 5.46TB each if you are wondering. They're fairly quiet, but you do hear them if you have it near you and they are active. Not the spinning, but more so the head moving. If you put them in a storage device and it's tucked away, you'll never know. Great choice for tons of storage!
I don't have any extreme brand loyalty in mechanical drives. They're becoming fairly uncommon in consumer computers, being generally reserved for long term storage of large amounts of data. USB 3.1 cables can transmit data faster than the drive can read or write the files, making internal SATA HDDs completely optional. Even so, I like to have a couple of traditional mechanical drives inside my computer case. Seagate is a huge supplier to OEMs of mid grade data drives. This specific model is not one of those. This is a big, heavy, solid, fast, and quiet HDD. I don't think they get much better than this.
I've used Synology NAS since around 2003 and pretty much found every drive maker has good and bad runs. HGST was the only drive I could say I had trust in.I've had three of this model (6GB ST6000NE000-2KR101) and so far they made it over 18 mo just fine.I like the extended SMART data branded under Ironwolf on this drive, but I'm holding off judgment, since every failed drive on my Synology I detected due to performance issues (freezing while copying files etc). I look at the SMART diagnostics and always states the drive was healthy. Um, yeah... Maybe the Ironwolf will do better.Bottom line, I just manage risk by only buying my hot spare when my performance tanks so I am not burning a warranty down just to have a hot spare. (I pay expedite costs if urgent.) ... MoreI've used Synology NAS since around 2003 and pretty much found every drive maker has good and bad runs.

(I pay expedite costs if urgent.) Second, I only buy drives that have 5 year warranties (more if I can find them) as three year warranties seem to crap out at 3 years, while 5 year warranty drives usually make it to five years. It's worth the up-charge since it reduces the risk to the data.It's a three star drive, while WD, Seagate are all 2 stars. Ironwolf version earns and extra star for at least attempting to provide something better than the useless SMART data.
Pros: The company offers a two year recovery on failed hard drives but the unit is extremely reliable that it’ll never get used.When you compare the cost per Tb, the 16Tb drive is inexpensive. (I tried to post the price paid but the review company insisted I remove it)Cons: I use the 14Tb drives in my Drobo 5D3 DAS drive and the 16Tb drives in my Synology DS1621+ NAS drive. The drives aren’t quiet like SSDs though each drive enclosure has additional fan noise too. Once the SSDs come down in price, that will be the big improvement but these Iron Wolf Pro drives are the way forward.
Pros: Despite hearing from multiple sources, the drives themselves aren't very loud at all. Your case fans have a good chance of drowning out the noise anyway. Performance on Unraid at least is very good and didn't really require a cache SSD as seems fast enough. Good stuff!
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.
ordered three, one was doa with click of death and not passing smart tests, but quickly replaced by BH. first time ive had a seagate that was doa always had good luck with them lasting forever. regularly get the advertised throughput of 240-300 meg/sec with them. i only have them on a sata ii 300 meg controller, not that they would work faster on sata iii. only issues is they are noticeably audible, not ridiculous but more so then the drives they replaced, and enough to turn my dogs head in wonder. so they are good in workstations or machine rooms, but might cause distraction if used when background noise is an issue such as recording with Mics in the same room. also, as is typical with hard drives they are exactly 6 trillion bytes, your machine will say they are ... Moreordered three, one was doa with click of death and not passing smart tests, but quickly replaced by BH. first time ive had a seagate that was doa always had good luck with them lasting forever. regularly get the advertised throughput of 240-300 meg/sec with them. i only have them on a sata ii 300 meg controller, not that they would work faster on sata iii. only issues is they are noticeably audible, not ridiculous but more so then the drives they replaced, and enough to turn my dogs head in wonder. so they are good in workstations or machine rooms, but might cause distraction if used when background noise is an issue such as recording with Mics in the same room. also, as is typical with hard drives they are exactly 6 trillion bytes, your machine will say they are 5.5TB. still around 10.6TB raw in a 3 drive raidz pool, and with compression even better. CMR per seagate.
