IronWolf 4TB NAS Internal Hard Drive CMR 3.5 Inch SATA 6Gb/s 5400 RPM 64MB Cache for RAID Network Attached Storage Rescue Services (ST4000VNZ06/006)

I installed this Seagate IronWolf 4TB NAS (CMR, 5400 RPM, SATA 6Gb/s, 64MB cache) into a home NAS setup for media storage and backups. Setup & Recognition: The drive was recognized immediately by the NAS system without firmware issues. SMART data looked clean out of the box. Performance: For a 5400 RPM drive, transfer speeds are solid and consistent for large file storage. It’s not an SSD, obviously, but for media streaming and backups it performs smoothly without noticeable bottlenecks. CMR vs SMR (Important): This is a CMR drive, which matters for RAID environments. Rebuild times are stable and performance doesn’t tank under sustained writes like SMR drives can. Noise & Heat: Runs relatively quiet inside the enclosure. Temperatures have stayed within normal range under moderate load. No excessive clicking or vibration so far. Reliability: After continuous uptime and regular data writes, it’s been stable with no errors or dropouts. Things to Know: – 5400 RPM favors reliability and lower heat over peak speed. – Best suited for NAS, backups, media servers — not high-performance workstation tasks. – Make sure your NAS supports 3.5" SATA drives. Bottom Line: If you’re building or expanding a NAS and want a dependable CMR drive designed for 24/7 operation, this IronWolf 4TB is a solid choice.

I recently put these Seagate IronWolf 12TB drives into my system after having them in storage for a while, and overall, they've been performing very well. The speeds are solid, and they handle data transfers smoothly, which is exactly what I was hoping for from NAS-class drives. So far, reliability and performance have met my expectations. That said, they can be a bit noisy when actively reading or writing. At idle, they're nearly silent, but under load, there is definitely noticeable drive chatter. I have my machine sitting right on my desk, so the sound is more apparent than it might be in a closet, rack, or separate room. If your system is close to where you work and you're sensitive to noise, you may want to consider that or plan on using good noise-canceling headphones. Overall, they're a great set of high-capacity drives with strong performance, just keep the noise factor in mind depending on your setup.

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. -------------------------------------------- UPDATE 06OCT2025 -------------------------------------------- I did finally receive the replacement WD RED Drive. WD sent me a white label drive instead of a RED label drive. It's basically the same drive but it has a label that looks like some printed on a thermal printer type label that they must issue when doing replacements or something. I didn't put it in my server. Instead, I have replaced 4 drives in my server with Seagate drives now. I even replaced my parity drive with a Seagate at this point, since it was a WD and started giving SMART warnings as well. So, the UNRAID server is almost entirely Seagate drives now and everything is running happy and smooth. The LSA HBA card has no issues with these drives at all and UNRAID sees them as normal SATA drives (normal as if they were connected to the motherboard directly)... just in case there are any UNRAIDers out there considering a LSA HBA card... I used a 9300 16i that was already in IT mode... zero issue with it with UNRAID... plug and play literally, the drivers come up automatically during boot. Anyway, the Seagate drives have been awesome so far.

I’m currently running five of these drives in my NAS, and they’ve been solid so far. Installation was straightforward, and they were recognized immediately without any issues. Once up and running, performance has been consistent for typical NAS workloads like media storage, file access, and general use. Stability has been the biggest positive. No dropouts, no unexpected behavior, and no signs of failure across multiple drives running together. That’s really what matters in a NAS environment. Noise and heat have been within a reasonable range for this class of drive. Not silent, but nothing outside of what you would expect for NAS-rated HDDs. Pros Reliable across multiple drives in a NAS setup Consistent performance for everyday NAS use Easy installation and recognition Stable with no issues so far Cons Typical HDD noise under load (expected, but worth noting)

Spindle drives are reliable, less expensive solutions for surveillance and NAS. They aren't as fast, but they make up for it in reliability. An enterprise NVMe drive has an expected life of 6 months in a NAS RAID. Enterprise M.2 & SATA III solid state drives last longer, but should always be installed as RAID 6 or double redundancy as they are not as reliable. Enterprise spindle NAS drives have 5 year warranties. The Seagate IronWolf PRO 8TB model is 7200RPM and CMR (AKA PMR). Understand that the warranty only covers the drive, not data recovery. That is why you are building a RAID in the first place. DO NOT INSTALL NAS DRIVES IN A SINGLE DRIVE FORMAT. Is it possible, yes. Is it a good idea, no. NAS drives do not have drive recovery built into the drive since you want the RAID controller to handle the error in order to ensure drive parity. Desktop drives such as the Seagate Barracuda are less expensive, and are able to handle errors at the disk level. Both drives prefer to run 24/7, but NAS drives are more sensitive to power cycling as well. For similar money to NAS drives, desktops and laptops are better off with NVME or solid state drives since they are faster and more power efficient. Just make sure to back up your data regularly since they aren't as reliable. The best part of these particular drives is how they are setup for a system builder. The package opens up to a drive in an anti static bag surrounded by bubble wrap. There are no instructions, software, hardware, or other things to get in the way. Less waste, and easy to handle packaging is a nice treat. If you do not have the parts to install the drives, you should seek other solutions. The drives are audible when they are seeking data on the platters. This may be annoying to some. The read / write speeds are spec for the SATA technology. Don't expect fast transfer rates. Expect a reliable RAID 5 or RAID 6 to protect your data. If you are setting up a new NAS, make sure you match the brand, size, revision, and firmware if possible. Never rely on software RAIDS also know as expanding RAIDS.

Plugged in and worked as advertised. Seagate has been a good product for me.

This particular drive failed on me. First Seagate drive to fail me in many years. It was still under warranty thankfully. The return process was easy although it wasn't super fast. I think Seagate was out of this particular drive when mine failed. I did message them about it and almost immediately I received a new drive which was larger than the original (16Tb). The new drive is working great. I still give 5 stars because of how I was treated by their customer service. They went above and beyond in my opinion. They certainly didn't have to issue me a larger drive, but did so anyway.

The drives themselves are great -- when they work, but when they don't you'll have to deal with a terrible, extended customer support situation. I have purchased 4 of these drives so far, and one has had issues since I received it. It started out causing random freezes in my RAID array, mount failures on startup, extended delays on shutdown, etc. After a few months, I was finally able to determine this was all caused by a hardware issue, and which drive was the problem because SMART started throwing out warnings about bad sectors. This is further confirmed, because after removing the drive the array functions without any issues. I started a warranty replacement with Seagate about a month ago now. To start, you have to pay return shipping when they send you a faulty drive. That's annoying, but not a dealbreaker. The drive is delivered and USPS/tracking confirms its delivery. After a few days, Seagate still shows nothing on my case number. I contact support, they say they require 10 business days after delivery before they will update your case status to being received. After 14 business days of no response, I contacted support again. They then say they never received the drive (AKA, Seagate lost it), and tell me to contact USPS to get a "Tracer". I contact support again after receiving the tracer, they say they'll escalate the ticket and have the warehouse look for it (you didn't do that already?!). I'm still waiting on a replacement drive, if I ever will get one. Supposedly, if they look for the drive they lost, and don't find it, they'll send a replacement drive. I don't see how any of this is my fault or problem though, and it's absurd that I still don't have the working drive that I paid for, but they refuse to send a replacement until they complete this search they should have done weeks ago. UPDATE: I have contacted support twice since this review, they never found the drive, they never sent a replacement. They also never contacted me at any point in this process. I have always had to wait and contact them again, even when a rep would confirm my email address and directly say they would email me. Supposedly, after this most recent conversation they are just sending a replacement. I'm not going to hold my breath, but maybe after over a month of this they're going to actually send a replacement. I also confirmed with support, that the other reviews are correct. They will only ever send a refurbished drive -- even though in my case I never received the new, working drive I ordered. It has been stuttering and causing freezes ever since I purchased it, I just couldn't figure out which drive was the problem before the return window. They also claim they will send the same model, so fingers crossed that's true (unlike what other reviews have state here). I have my doubts though. I'll never buy Seagate again. UPDATE #2: The saga continues. My ticket was marked as "completely processed" and I was never sent a replacement. I confirmed with support that they also don't have a tracking number. Only time will tell if I ever get the USED drive I paid full price + extra shipping + many hours for. UPDATE #3: I finally got a replacement drive. Surprise! It's completely DOA. It doesn't spin up, it just beeps (indicating internal component failure). Starting all over with this whole process (almost a year after placing the original order). At least they provided a pre-paid shipping label to send back the dead replacement drive they sent me.... UPDATE #4: I did finally get a hard drive that worked... but a couple months later a different drive (I have 4, all ordered about a year ago) started failing. Bad sectors, completely unreadable, could not be allocated. This would mean data loss/corrupted files, if this drive was not in a RAID array with redundancy. At this point it is almost comical how unreliable these drives are. DO NOT buy these! UPDATE #5: Another dead-on-arrival replacement "certified rerfurbished" drive. Doesn't spin, just beeps. Tried it in my NAS, desktop, and an enclosure. The drive is completely non-functional. This company is a joke.

شريت هارد الاول للسيرفر واستغربت من اداءه الخورافي رحت طلبته حبتين ثانيات بس للاسف ضاعت وحده وعوضوني امازون لكن الهارد خورافي اشتره وانت مغنض خاصة ذي الشركة

Simplemente amo este disco duro, es de muy buena calidad, la velocidad de carga me encanta, hay superiores de 128mb pero este me parece perfecto por el costo, para mucho es ruidoso, pero lo normal, nada fuera de lo común, la garantía es brutal, recuperan tus datos sin ningún problema en caso de fallos, de uso continuo y constante, con protección de vibración y chip de apoyo en caso de cortes de energía, ojo también el factor de forma no es para todos los gabinetes, hay que notar los espacios de los tornillos, además que es compatible con los Time Capsule de la marca de la manzana. Lo monté en mi NAS synology y jala muy bien, no se calienta, además que aparece con el logo de IronWolf, tiene prestaciones más amplias por el modelo. En definición recomendable por velocidad, espacio y costo-calidad.

I purchased two of these drive for use in my Synology Nas. These 7200 rpm drives are great performers. Definitely faster than the 5400 rpm drives that I had before. Synology also supports Ironwolf Health Management system, so I should get better warning of a drive failure. Theses drives have the better read/write error rate and come with a 3 year warranty and 1 million hour mtbf.

الهاردديسك له فتره عندي وهلكته بالملفات ولا اشتكى وسعره مقارنه بغيره ممتاز

Il prodotto si presenta bene, e assolutamente all'altezza della situazione, testato, veloce, affidabile spero che nel tempo mantenga i dati che alla fine di un Hard Disk questa è la cosa più importante, devo lamentare alcuni rumorini molesti all'accensione che con il WD Caviar red non ho mai avuto, in definitiva se mantiene i dati va benissimo, legge a circa 150 MB al secondo non ci si può lamentare
