16TB IronWolf Pro Internal NAS Hard Drive | SATA (ST16000NTZ01) | 7200 RPM. Professional NAS HDD. 24/7 performance, AgileArray, All-CMR, 550TB/year, health monitoring.

I bought the Seagate IronWolf Pro 16TB for my NAS setup, and it's exactly what I needed—reliable, spacious, and enterprise-grade through and through.First off, 16TB of storage is a glorious amount of space. I’ve loaded mine with Plex media, backups, and surveillance recordings, and still have room to breathe. This is proper CMR technology (not the dodgy SMR stuff), which is a must for RAID performance and data integrity.The 7200 RPM speed and 256MB cache make a noticeable difference, especially in multi-user environments. Transfers are fast, consistent, and there's no lag when indexing large volumes of data. It runs smoothly in my Synology NAS with zero fuss.Noise and vibration levels are surprisingly reasonable for such a large-capacity drive. It’s not silent (it’s spinning 7,200 RPM after all), but Seagate’s vibration dampening tech is doing its job well. Temps stay in check too.Bonus points for:RAID optimization – it just worksData Rescue Services included – peace of mind in case disaster strikesFrustration-Free Packaging – arrived safely, minimal waste, no nonsenseFinal thoughts:If you're serious about long-term storage, RAID setups, or just want a rock-solid drive that won’t blink under pressure, the IronWolf Pro series is well worth the investment. Yes, it’s not cheap—but this isn’t your bargain-bin hard drive. It’s a heavy-duty workhorse made for people who care about their data.Highly recommended for NAS users, small business setups, or any data hoarder with standards.

I grabbed the IronWolf Pro 8TB because my NAS was running out of room, and honestly, it’s been spot‑on. Slotted it in, powered up, and it was recognised straight away with no fuss. It’s been running quietly in the background ever since, doing exactly what I needed it to do.Nothing flashy, nothing dramatic — just a reliable, fast drive that gives me the extra storage I needed. If you’re expanding your NAS and want something dependable that you don’t have to think about again once it’s installed, this one’s been great for me.

Excellent performance and ease of installation (push fit SATA plugs). Slightly noisy but acceptable for a spinning HDD. This is 7200 rpm, so faster access. The device is recognised easily in Windows Device Manager. I went for 4TB but many storage capacities are available. I have used Seagate since the early days of PC / Windows, so over 30 years, have never been let down. I bought this as a back storage internal drive for my new PC project. Robust and reliable and very well made.

If you are building a NAS or upgrading your home server, you probably already know that IronWolf Pros are the gold standard. I popped this 8TB into my bay and it was recognised instantly.The key thing here is that it’s a CMR drive (not SMR), which is vital if you care about your data integrity in a RAID setup. The transfer speeds are consistently high and it feels bulletproof.Just a heads up: These are Enterprise-grade drives, which means they are designed for performance, not silence. You will hear the familiar "chugging/clicking" noise when it’s writing data. It doesn't bother me—it actually reassures me it's working—but don't expect it to be silent like a standard desktop drive. Expensive, but worth it for the peace of mind.

Its a hard drive. Not a great deal you can say there other than it works. Expensive, as all storage media is today, but it passed integrity checks and had no issue with registering the warranty with seagate. The one big thing buyers should be aware of is the noise during read and write tasks. This was my 2nd ironwolf pro drive purchase so I was already aware of the noise these drives make. Both drives 10tb and this 16tb) click-clack at about the same volume. For people more used to quieter drives in their pc, the iron wolf drives are considerably louder in my experience of two drives I've purchased. Apart from noise levels and extortionate drive prices at this time, I have no complaints about the iron wolf drives.

Excellent works very well in friends NAS

few random info i want to sharethis is made for 24/7 use. I brought 20TB for cold storage but the ideea is that if you buy it to play off it or few times per week use, then you are risking to damage it since it's not made to turn off and turn on, that is the Green one (baracuda) for, and the blue (sky something bird) is made to also go 24/7 but that one is for video registration and not play data. Aka you need to chose based on your reason to buy. Like the Exo, those are over kill unless you do need for a company. Also very noisy.The pro is better then the non pro so i will say it from now that if you just want a temporary HDD you are better to get an ssd or the firecuda (a combination of ssd and hdd).This unit has better tehnology to survice.even if you use it once per month or less, ensure you do use it more then 2 times per years since the lubrifier might dry out otherwise and you can't open this case unless you have a special way to rebuild it.The noise level is larger because performance and such was chosen over quiteness. and again, the green barracuda is better if noise is an issue.Also the green and the blue are using les electricity while this one uses more, way more.Did you see this one says 7.200 RPM? that is how fast the unit is. Meaning if you see a Iron Wolf Pro that has 5k something, that one is still an iron wolf pro but an older version but maybe it's better for you? Anyways, i mentioned this because there are a lot of mix ups when people buy a 7.200 RPM and get the more older model that is good, but not as good.Speaking of mix ups: be carefull that even if it's new, it might not be new since a lot of scammers are take used ones, use software and such to create false information the hard drive will give, and sell them as New. You then get it, check it quickly, no issues, and that is just because as i said, they do something with it. And then? It breaks, and you find out your product does not even have warrenty.as in, it's very importand who you buy it from, where you are buy it from. The 5 years warrenty and the 3 years data recovery only are valid if it's new, and sold by a Seagate aproved. Aka if you find this pro online, it does not matter if they are brand new, because if seagate did not aprove of the seller and that person sells them, it means that those are either "refurnised sold as new" or stolen ones.Speaking of scammers: buy external hardrive is even riskier since some buy, exchange, then return.... if not even the employee themselfs... and the person who buys it next will be accused of fraud since the check on the hardrives shows it's a different one then it should.Now, when i got the 20TB i was very worried since it came in an brown box, and has just a label??i filmed me opening <- ensure you are covering everything since any scamer will just accuse you of being the scamer like: exchange new with old, and now want refund/replacementThere needs to be a sealed bad that is transparent. Keep that bag very safe since it's anti statick so be carefull to keep it because one mistake and you touch the hardrive and all the data is gone <- wash hands, let them dry, touch something metalic, if you get electrocuted, you just prevented killing your hard drive. Avoid chloding, or anything like that, even rubber (latext) grolves. And again, you only need clean hands, since the anti static gloves are for people who build a pc or similar cases where they know even better.the sealed bag, that should 100% be sealed, as mentioned, it's transparent enough to see through and get the SN (serial number).Before opening the bag, register your device on seagate since that will help you.Why? some of the scammers sell devices (probably stolen?) from different regions and sell it to you but the warrenties and such are region base so it might not be valid just because you are in the wrong region.also, if you register your product, then you film that you have that device, then that you open it, this is further copy of non tempering since the device with the SN on it, is still sealed in the bag, and only open after while ensuring you keep filming since scamers will jsut say you reglued the stiker to an old one <- aka exactly what they actually did.Also, if anything seems off from the start, don't even open the bag.also seagate csBTW: the registering the product is very important because thiefs exist. You are covered, and most of all, you have verified it's warrenty.also important, is to get a good case for this since it gets easily hot.A lot of people wonder Seagate vs WD vs others. Honestly, the only time it matters is if you know what you are looking for and one or the other, don't have said hdd avalable. Otherwise? there is no difference with the devices themselfs. So what then? it's the warrenty, how long, data recovery (this is why get pro and not the non pro) included for 3 years, and less people online saying how they like WD better when the same arguments and "statistics" exist reverse.Ensure you are verifiyng the hard drive via softwares and such.if you buy the 20 TB or more, keep in mind that a ful test will take anywhere from half a day to 2 day ish.Regarding the case, ensure it's Sata 3.5 inch compatible. Because most of the laptops and such are only 2.5 so don't look just at the price.Also it needs to be SATA, because even if a device is 3.5 inch, if it's not SATA then it's something else and that case is not good for this internal hard drive.Moiser that is to high or to low will damage it. Aka dry lips, or dry eyes, or dry through, do you get what i mean? we too are constantly "wet" but not to the level where we drown <- btw, if you ever jump out from a plain or so, be carefull of clouds since death via drowning is real since everywhere is a gas full of water. And this is where i want to get: storing it. You need to be carefull that it's not to wet or else rush. And i hopeyou always rember the cloud exemple that it does not matter if it's in water or not, water exist in air and that is why you need to seal it if not used.on the same ideea is dust.Also the more you use a hdd the more it vibrates causing damage to itself... well this is why, once again, buy the pro and not the non pro because the pro has anti vibration so you can use it without it wearing itself out.when you plug it in for the 1st time, you will not see the hardrive since you need to open storage and stuff to configurate <- i intentionally did not say all the details so you get an ai to tell you, also yes, it does not need to be paid ai i just want to make sure someone is "helping".also the exFAT means you can connect this driver to anything and it will work. Downside? any issue, like the cable got disconnected, then the hardrive's content get's corrupted.While the other one, NTLF or whatever it's called, is not really for general use, like it might not be compatible with non windows devices. However that one is safer since it does a log of what is going on so it won't forget what you did .Regarding the forget. When you delete files, pc, hardrive, phone, so on, you are not actually removing the file, all you do is disconnect it so that nothing can see it anymore. And once you put new files, those files will be covered and now really removed. Or to put it differently, the data recovery work because your files still exist, but they are pieces and can't be easily found (imagen a glass bowl that shattered and now you need to find everything.and above is also important if you plan to sell the hardrive in case you had private or otherwise information because they still exist on it. Aka fill up the hardrive with junk before selling, plus like this you'll have proof you did not scam.Regarding the format: quick format is quick because it just disconnect the files from the device but the files still exist.A full format, is when everything, every last thing is scanned, as such of course using it for the 20TB will take more then 12 hours, if not way more.Anyways, i hope this helps some people because the 20 TB is not only very expensive, you definitly do want to ensure you know as much as possible how to ensure you can buy this product, mentally and otherwise, prepered since please don't forget. One single mistake, it's gone. This is why it's always better to get spare ones, even if second hand, and any personal folder, once you encrypted, to be in a cloud storage but again, encrypt it, since hackers might "break in" and take your files, crak passwords and zips, so encrypting the file is very important. But otherwise? this 20 TB will be very good for many year to come!

So far so good. 775€ was a good price for 24tb. Now they are way to expensive.It fits good in my ugreen Ai nas idx6011 but need more disk soon 😜😋

Es un bicharraco. Grande, grande en capacidad, silencioso y rápido.Llegó muy bien envuelto y en perfecto estado.Tras escaneo de superficie está perfecto en cuanto a sectores.Como es de Helio suele tener 3 grados menos que el resto de discos con los que está.Muy contento con él y repetiría.Espero que esta reseña sea de utilidad.

Chi gestisce un NAS sa che il risparmio sugli hard disk è un rischio che non vale la pena correre. Ho scelto questo Seagate IronWolf Pro da 8TB (modello ST8000NTZ01) per aggiornare il mio array RAID, e le differenze rispetto alla serie standard o ai drive desktop sono evidenti sin dai primi test di stress.🛡️ TECNOLOGIA E AFFIDABILITÀIl punto di forza di questo disco è la tecnologia CMR (Conventional Magnetic Recording). In un ambiente NAS, dove i riscritture sono frequenti, evitare i dischi SMR è fondamentale per non avere cali drastici di performance durante le ricostruzioni RAID o i backup pesanti.Sensori RV (Rotational Vibration): Essendo la versione Pro, include sensori per gestire le vibrazioni rotazionali. Nel mio case a 4 bay, questo garantisce che le vibrazioni dei dischi adiacenti non influenzino la precisione della testina, prolungando la vita del drive.Carico di lavoro: Certificato per 550 TB/anno, è un mulo da lavoro instancabile, ben oltre le necessità di un utente domestico avanzato.🚀 PERFORMANCE REALIVelocità: I 7200 RPM e la cache da 256 MB si fanno sentire. Nei trasferimenti sequenziali ho saturato stabilmente la banda della mia rete Gigabit, mantenendo medie intorno ai 240-250 MB/s in lettura/scrittura sequenziale.Rumorosità e Calore: Nonostante i 7200 giri, il disco è sorprendentemente silenzioso durante il normale funzionamento (si sente il classico "grattare" solo durante i seek pesanti). La temperatura operativa in un case ben ventilato si è assestata sui 36-38°C sotto carico.💎 IL VALORE AGGIUNTO: DATA RESCUEUn dettaglio che spesso si ignora finché non è troppo tardi: inclusi nel prezzo ci sono 3 anni di Rescue Data Recovery Services. Sapere che Seagate offre il recupero dati professionale in laboratorio in caso di guasto meccanico aggiunge un livello di tranquillità che giustifica il sovrapprezzo rispetto alla serie IronWolf liscia.✅ PRO E ❌ CONTROPRO: Tecnologia CMR (indispensabile per RAID); 3 anni di recupero dati inclusi; prestazioni al vertice della categoria 3.5"; Garanzia di 5 anni.CONTRO: Prezzo superiore ai drive consumer; leggermente più udibile rispetto ai modelli a 5400 RPM (normale per un drive Enterprise).💡 CONSIGLIO TECNICOAppena arrivato, consiglio sempre un test completo della superficie (Extended Smart Test) prima di inserirlo nel volume RAID. La confezione FFP (Frustration-Free Packaging) di Amazon è ottima: il disco è arrivato sospeso in una struttura di plastica rigida e cartone, protetto perfettamente dagli urti del corriere.GIUDIZIO FINALE:È il "Gold Standard" per chiunque prenda sul serio i propri dati. Che sia per un server multimediale Plex o per backup aziendali, l'IronWolf Pro è una garanzia di continuità operativa.

Not a trustworthy seller. Upon checking the hdd serial number on seagate, no warranty was left on the hdd. Also no recovery plan as wrongly advertised.Most probably that is not an authorized distributor.

The Disks came in original Seagate packaging and with a 3 year recovery warranty card for each packaged disk.I am using 4 of these Disks in a RAID-5 array setup in my UGREEN 4-bay NAS DXP4800 PLUS and THEY perform great.They don't make a lot of noise, everything is within norms.I highly recommend these Disks for this kind of high redundancy arrays. I will setup another one so they can rsync to eachother.
