Seagate 4TB IronWolf NAS SATA Hard Drive 6Gb/s 256MB Cache 3.5-Inch Internal Hard Drive for NAS Servers, Personal Cloud Storage (ST4000VN008), Silver

Pros: - No issues with test, installation, or data transfer - Work well with Enterprise level Adaptec RAID card - Good features on the 4TB and larger drives - Personally experienced long term reliability of Seagate drives (Used Seagate for years, 25+ drives from 40GB to 3TB prior to this purchase) Cons: - Had to spring for the 4TB drives or larger to get the rotational vibration sensors (unavailable on smaller capacity Ironwolf drives) Even though I have been using Seagate drives almost exclusively for all of my spinning disk drives, I was open to using any reliable manufacturer to replace my six 1TB Seagate drives with four 4TB ones. My drives run in a RAID 5, with a spare, in my personal server and longevity is important. I usually run drives 24/7 for about 5 years before they are replaced. I was very close to purchasing four W brand drives due to the positive reviews, but finally settled on Seagate because most of the failures of Seagate drives seemed to be "infant mortality" failures (happen very early in the product life), where the W brand drives seemed to fail more often around a year after purchase (based on reviews on Amazon). This was true when I ordered prevously ordered a Seagate 3TB backup drive and it had failed out of the box. It was much more convenient for me to run hours of testing on each drive before installing them and replace them early rather than having the drives work well for a year and then having to submit a warranty claim. When I received the drives, I ran approximately 13 hours of testing on each 4TB drive by performing a Long test using the Seagate tool. I checked the SMART data before and after and this test seemed to read all of the data from the entire drive because the SMART data after the test stated that 4TB of data had been read. Because of my RAID 5 and my backup strategy, this was enough for me to depend on the drives in my server and I installed them. I configured the RAID 5, restored the backed up data to the drives, and then performed a build/verify on the RAID. The data transfer from the backup of my 2.3TB of data was much quicker than I expected and my server was back up and running. The drives are not louder than some of the loud parts of my server (server fans and a 300GB 15k RPM SAS OS drive), so I would not be able to provide details to how loud the drives are. The performance is improved over my six 1TB Barracuda 7200 RPM drives and I am pleased with how the transition was.

I was between this, the HGST and WD RED 4TB NAS HD's for my Synology DS212J. I, like I tend to do, agonized for a long time before deciding which to purchase. At the time I bought these (cyber monday 2016) the HGST was the same price as the Seagate Ironwolf, and the WD Red was $15 more. After extensive review reading, spec reviewing, etc. I decided to go with this drive. My reasoning behind this was the fact that this was a newer generation drive with technology integrated to provide more features and benefits related to NAS use than competitor NAS drives. Also, for the supposed 1% failure rate of the HGST I was surprised to see as many negative reviews as I did. Red's seemed like a coin toss to me. Seagate has done a lot to improve the reliability of their drives in order to stay competitive in this market. I felt confident in my purchase, and I still do. The last (2) Hard Drives I put in this Synology NAS were 1TB WD Blacks. Both of the failed immediately out of the box and had to be RMA'd (purchased from Newegg). I know black wasn't correct for NAS, but at the time I purchased the NAS I wasn't exactly flush with cash so I bought what I could afford. I left them as separate volumes with no RAID or JBOD, that way if one failed only the data on it would be lost. Both of the replacement WD Blacks have lasted since December 2012. One of them will now only write at 12MB/s, but is otherwise okay, and the other one is in perfect working order. Over the years the data on those drives become more and more important. I decided that it was time to upgrade to a decent capacity and to go RAID 1 for redundancy data protection. The Synology took almost a full day per drive to perform it's initialization and error checking process but both of these Seagate 4TB Ironwolf drives work flawlessly. They operate quiet as well. The only con is the write speeds. The WD Blacks I had were 7200rpm and the 4TB version of the Seagate Ironwolf is only 5900RPM. I've got gigabit Ethernet and other than the drives, no other variables have changed. The fully functioning WD black I could write on, from my PC over the wired network, to the tune of about 20MB/s. The weak WD Black could only write about 12MB/s. The Ironwolf is 10MB/s. Now it should be noted that before the WD Blacks were individual volumes and not in RAID. These Ironwolf drives are in RAID 1 so that may cause a little slow-down on the write speeds I suppose. I'd recommend, to anyone who could afford it, to get this drive in either the 6TB (because it's 128MB cache and 7200rpm) or 8+TB (because it's 256MB cache and 7200rpm). If you're like me, and money is a consideration and you're willing to sacrifice a little speed to get a better dollar to terabyte value then you really can't go wrong with the Seagate Ironwolf 4TB (lower capacities not a better value at current $:TB). Edit 12-30-16: I'm not really sure what happened because I haven't changed anything but the consistent write speed of a large video file (3GB+) is about 19MB/s and smaller files (like 300MB) are like 22-25MB/s. Obviously the initial burst is higher, but this is what the data transfer speed drops to once it settles down.

OEM and works as expected. Boxing was nice too, it was placed inside 2 carton boxex with bubble wrap on the HDD. Other sellers would use the bubble wrap filled with air for more protection. But no damage to my received product.

Bought this 4TB Ironwolf to put into my Argon EON but then a year later it found it's way into my TrueNAS server for media files. It works great but now I have to buy more space. Definitely will buy from DBSKY again

The drives arrived packaged perfectly by Amazon. See photo. Each in their own little box with the cushioning feet attached. Then in a larger box with bubble padding. I bought 4 of these drives and set them up in a raid 5 configuration in an enclosure. The drives passed 3 certify passes in SoftRAID with no errors. I have this enclosure right next to my computer and can barely hear them operating. They do not seem to run hot at all and I’ve put them under heavy load. These drives, in this configuration with thunderbolt 3 connectivity, are almost as fast read speeds as my internal hard drive. I have always used WD drives so I was nervous about switching brands but so far they’re great. Amazon’s great price and a 3 year Seagate warranty were nice too. December 17,2018 - one of the drives developed excessive bad sectors after only 830 hours of use. The RMA process with seagate is confusing as you never get to actually speak to a human. I have never done an RMA with anyone before so am not sure how long it will take to get a new drive.

I have... let's see... two 2 TB Iron Wolf's (left over now), four 4 TB Iron Wolf's, four 6 TB Iron Wolf's, and four 12 TB EXOS X16 drives, (if you want to count those.) To make this work the best way possible, I had to order two more of the 4 TB drives. (I already had two - in a really weird combination RAID with the 2 TB drives.) They got here and I put them in one of the NAS's with the other 2 and it's synchronizing them right now -- FLAWLESS, as usual! They came in an electrostatic bag, in a sausage link-sized bubble wrap thing I've never seen anything like! Superbly packaged. All that so I can say: I have NEVER had EVEN ONE problem with an Iron Wolf (or an EXOS) hdd. I need more stars to give them. And, at least in an Asustor NAS or a Synology NAS, there's no beating the SMART monitoring.

I've had this drive for less than two months and its health is already at around 40%. It fluctuates anywhere between 38-44% at any given time. This drive isn't even used all that often. It might be accessed once or twice a day if it's lucky. This is total BS. I gave up on WD because of there poor QC. Now I have to deal with this with Seagate? Come on people! UPDATE: Contacted their customer support and they won't even discuss this issue any further until I download their own DOS boot drive tester, run a (destructive) test and send them a screen cap of the results. HOW DO YOU EVEN TAKE A SCREENCAP IN DOS?!?!?!?!?! Seems like a lot of hoops to jump through for a replacement. Also, if you're a Mac user, your SOL because their test is DOS only. Most other drive manufacturers will take the drive back and test themselves. This is dumb. This is the first time I've had a problem with a Seagate product that I've purchased myself, and I have to say that this is VERY disappointing. UPDATE 2: So I finally got a replacement for the bad drive. And the new one works like a dream. After all that was said and done it was actually really easy. So I presented all my finding, including that stupid DoS test (took pics with my phone), as well as whatever I had shown them through DriveDX. The guy on the phone told me that it still wasn't enough to prove anything and that the only way I could get a warranty replacement was to tell him that the drive was making noise. so, I told him the drive was making noise. He said, "Ok, I'll send out a replacement immediately!" Done and done. Lame. So pro-tip to anyone that doesnt want to deal with any BS: Just lie. Its better than what I had to go through, which was deal with customer service BS, buy another drive to transfer all my data and run a stupid test that wiped my data which showed the same results as the test that didnt require a full wipe.

So far so good, installed four of these into a fresh RaidZ2 freenas server, no issues with installation or imaging. freenas shows all four running nice and steady. I'll update if there are any issues down the road, but for the price I'm pretty happy with them. One comment about the packaging- I'm not sure where these things shipped for, but the inside of the main box all of the drives were in smelled like a freaking laundromat. VERY strong detergent smells in that box, once I got the drives out I had to carry the boxes out to the dumpster because it was stinking up my office! The drive boxes themselves didn't have the odor, and the drives were sealed inside anti-static bags anyway.. so just a random comment! Edit: 4 year update, they are still going strong!

Ho acquistato questo Seagate IronWolf da 4TB per il mio NAS domestico e sono davvero soddisfatto. È molto affidabile, progettato per funzionare senza interruzioni e gestire carichi di lavoro continui. Le prestazioni sono ottime, con velocità di trasferimento costanti e una buona gestione dei dati in RAID. Inoltre, è molto silenzioso durante l’uso, cosa che apprezzo molto soprattutto perché il NAS è in casa. La capacità di 4TB offre ampio spazio per backup e archiviazione di file multimediali. Nel complesso, un prodotto di qualità che consiglio a chi cerca un hard disk robusto e performante per il proprio sistema di archiviazione.

The harddisk works great. I use it for security so it is important that it makes no noise.

Dependable drives, no issues great product

J'ai récemment acheté le disque dur interne IronWolf de 4 To pour mon NAS et je suis très satisfait de mon achat. Sa capacité de 4 To est idéale pour mes besoins de stockage, et les 64 Mo de mémoire cache améliorent nettement les performances. Ce qui m'impressionne le plus, c'est son silence de fonctionnement. Même dans un environnement NAS multi-utilisateurs, le disque dur est presque inaudible, ce qui est essentiel pour moi puisque le NAS est situé dans mon espace de vie. En termes de fiabilité, le système IronWolf Health Management intégré offre une tranquillité d'esprit non négligeable. C'est un vrai plus de pouvoir surveiller l'état du disque en temps réel. La garantie limitée de trois ans et les services Rescue Data Recovery inclus sont également des avantages appréciables. Globalement, ce disque dur répond parfaitement à mes attentes en termes de performance, de silence et de fiabilité. Je le recommande vivement à tous ceux qui cherchent une solution de stockage efficace et durable pour leur NAS.

Film arşivimi depolayıp Plex üzerinden ağdaki diğer cihazlarda izlemek için aldım bu HDD'yi. Başta biraz çekimserdim, aynı anda iki farklı cihazda 1080p film oynatırken devir hızının 5900rpm olmasından kaynaklı takılmalar olur mu ya da arşivimi buna atmak çok uzun sürer mi gibi çekincelerim vardı ama bilgisayarda takılı 7200rpm 256mb tampon bellekli Seagate Barracuda'dan bile daha hızlı çalıştığını gözlemledim. Samsung Magician yazılımıyla test ettiğimde de Barracuda'nın ardışık yazma hızı 72MB/s çıkmışken, IronWolf'un ardışık yazma hızı 130MB/s çıktı. Ardışık okuma ve IOPS değerleri ise aynı gibi, ufak farklar var. Barracuda modeli olan HDD de henüz 1,5 yıllık, sağlığı %100 olan bir HDD. Kısacası 5900rpm, 64MB tampon bellek değerleri hiç kafanıza takılmasın, hızı sizin kullanım şekliniz için yeterli geliyorsa RPM'in düşük olması daha bile iyidir, daha sessiz ve titreşimsiz çalışır diskler. Tek sıkıntı HDD gibi mekanik ürünler darbelere karşı bu kadar savunmasızken bunları koymak için ufak birer karton kutuların bile çok görülmesi. Amazon ile alakalı değil, bunlar direkt fabrikadan bu şekilde geliyor satıcılara. Aldığım bir sleeve kablo bile karton ambalajıyla satılırken maruz kalacağı darbe, titreşim, manyetizma gibi şeyler tarafından kolaylıkla bozulabilecek HDD'ler bulk packaging denilen korumasız bir ambalaj ve incecik bir baloncuklu desteğe sarılı geliyor. BarraCuda'yı yine büyük bir mağazanın şubesinden elden satın almıştım, o da öyleydi. Neyse ki iki HDD'de de bir sorun yaşamadım ama son kullanıcının eline ulaşana kadar HDD'nin başına bir iş gelme ihtimali bu kadar şans işi olmamalı.
