Seagate 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 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.

Excellent hard drive. I’m using it in my backup NAS running OpenMediaVault, and it’s been a real workhorse. Super fast performance, quiet, and rock solid in RAID. Seagate IronWolf drives never disappoint — highly reliable for 24/7 NAS use.

My in laws recently had to move into a new warehouse. After getting quotes up the yin yang to install security cameras in the facility (everything also tacked on monthly "cloud" subscription costs) we decided to go the DIY route. We ended up with Reolink's 32 channel capable system and hooked up 24 of the 32 channels. The 32 channel system comes with NO hardrive so you buy what fits your needs... Enter this hard drive. Installation is easy just mount and hook in the power and sata cables. The NVR had no issues formatting then writing onto the drive. Playback had no issues and all 24 channels records at the max 4k res and capturing everything important in the facility. Great bang per gig buck along with being a NAS drive - it should go on for many years. Solid drive - easy and straight forward - works in the NVR capturing 24 ip streams - love it! Going the DIY route btw did save us over 15K and got better equipment to boot!

The HDD war installed in NAS and works perfect. The shipment is delayed, but the quality is superior.

Oh My Gosh this thing is noisy. I can clearly hear them from across the room when its quiet. Given the year and the advancement in HDD tech, they should be nearly silent. As in if you stood a foot away from the enclosure, with no noise around, just barely hear something. Nearly every other drive I've bought is that quiet. Not these babies! I had a set of 4 TB Western Digital drives, in a QNAP NAS. One went bad, and due to age, I decided to just upgrade. The NAS is in a FROG which serves as a spare bedroom when people drop by. This thing is sooooo nosisy that I will need to turn it off over night so they can get some sleep. Sure, they are performant. Sure, the NAS seeoms slightly more responsive (it is RAID 5) but .. I kida wish I'd bought WD's again. Never hear them. Nevvaaah!

While the drives appear to be operational, and I am using one of them now, I am very displeased with the way the drives were shipped. The two drives, in their little plastic sleeves, were simply tossed into a plastic bag with no padding or ESD protection whatsoever. I don't know who decided this was a good idea, but it goes against every recommended treatment of a hard disk drive. The plastic bag was not gently handled, as shown by the condition of the bag. The plastic bags around the drives show evidence of impact and abrasion. I don't know how this will affect the lifespan of the drives, but it certainly won't improve it. Whoever is responsible for packaging such delicate electronic items needs to be held to a higher standard. I tried to find a place to tell Amazon, but if it exists I was unable to locate it, hence the product review. I did give it 5 stars because the drive looks like it works, but only time will tell. Update: I had to return the second drive as it was defective. Noisy rotation, clicking sound as the head was seeking, and never would initialize. Very likely the drive failed due to shipping damage.

Works like it should.

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.

Working fine for the past three months, at software Raid-0 they are a bit slower than sata SSD on small files transfer, but with bigger files 10gb+ it is constantly faster, because when the SSD cache get filled the speed plunge

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

Ordered on 27 Jan, received on 10 Feb. Delivery was slow, but the hard disk is cheap and worth every penny. Genuine and brand-new.

Es de los mejores discos que he comprado, Seagate es una de las mejores marcas en el mercado en cuando a almacenamiento de datos se refiere. Les recomiendo que descarguen el software de Seagate (desde la página oficial) para comprobar que el disco no tenga problemas de fabrica, antes de comenzar a escribir datos en el. Es un poco ruidoso obviamente ya que es un disco duro mécanico HDD, no es un SSD. Lo volvería a comprar, definitivamente.
