Seagate IronWolf Pro, 12 TB, Enterprise NAS Internal HDD –CMR 3.5 Inch, SATA 6 Gb/s, 7,200 RPM, 256 MB Cache for RAID Network Attached Storage (ST12000NT001)

When you're building or upgrading a NAS system, drive reliability is paramount. The Seagate IronWolf Pro is designed specifically for enterprise NAS environments, and it delivers the performance and durability you need for always-on storage. This is a serious drive for serious storage needs. The 8TB capacity provides substantial storage space for a single drive. Whether you're storing large media files, running virtual machines, or handling heavy data workloads, having 8TB per drive means you can build high-capacity arrays without needing excessive drive bays. The capacity-to-cost ratio is excellent for this performance tier. CMR (Conventional Magnetic Recording) technology is a key advantage. Unlike SMR drives that can have performance issues with certain workloads, CMR provides consistent performance for NAS applications. Write operations don't bog down, and the drive handles simultaneous read-write operations smoothly. That consistent performance is crucial for multi-user environments. The 7200 RPM spindle speed delivers solid performance. Data access is quick, transfer rates are strong, and the drive handles demanding workloads without bottlenecking. Whether you're streaming multiple 4K video files or running database operations, the performance keeps up with what you're asking it to do. The 256MB cache is generous and helps with performance optimization. Frequently accessed data stays in cache for faster retrieval, and the drive can manage multiple operations more efficiently. That large cache contributes to the smooth, responsive performance you experience during actual use. SATA 6Gb/s interface provides the bandwidth needed for high-performance NAS applications. The drive can saturate the interface when needed, delivering the throughput that modern NAS workloads demand. Transfer speeds are consistently strong across different file types and access patterns. Build quality and reliability engineering are where the IronWolf Pro designation matters. These drives are rated for higher workload limits than consumer drives, with specifications that support 24/7 operation. The mean time between failures is rated at 1.2 million hours, indicating enterprise-grade reliability expectations. Vibration tolerance is engineered for multi-drive environments. NAS enclosures typically house multiple drives running simultaneously, which creates vibration. The IronWolf Pro is designed to maintain performance and reliability even with the vibration levels present in populated NAS chassis. That tolerance prevents performance degradation and premature failure. Noise and heat levels are reasonable for a 7200 RPM enterprise drive. It's not silent – there's the characteristic spinning platter sound – but it's not excessively loud either. Heat output is manageable with proper NAS ventilation. These drives operate within acceptable temperature ranges in well-ventilated enclosures. The rotational vibration sensors actively monitor and correct for vibration in real-time. This technology helps maintain performance and positioning accuracy even when multiple drives are working simultaneously in the same enclosure. It's one of the features that distinguishes NAS-specific drives from desktop models. Data recovery services are included for three years, which provides additional peace of mind. If a drive does fail and you need professional data recovery, having that service available can be invaluable. While you should always have backups, having recovery service as a safety net is reassuring. Power consumption is optimized for NAS environments. The drive balances performance with power efficiency, which matters when you're running multiple drives 24/7. Lower power consumption means lower operating costs and less heat generation in your NAS enclosure. Compatibility with major NAS platforms is excellent. Whether you're running Synology, QNAP, or another NAS operating system, these drives are recognized and work without issues. Seagate provides compatibility lists and optimization guides for popular NAS brands. Performance consistency over time remains strong. These drives don't show significant performance degradation as they age. The combination of quality components and robust firmware keeps them running reliably throughout their service life. Warranty coverage at five years demonstrates Seagate's confidence in these drives. That long warranty period provides protection for a substantial portion of the drive's expected lifespan. Having that coverage matters when you're investing in enterprise-grade storage. For anyone building or upgrading a NAS system and needing reliable, high-performance drives, the IronWolf Pro is an excellent choice. It's engineered specifically for NAS workloads, delivers consistent performance, and provides the reliability needed for always-on storage systems. Whether you're setting up a home media server or deploying small business storage, these drives give you enterprise-level reliability at a reasonable price point.

got the used / mint condition by amazon, irowolf pro 8TB kinda wish the package said fragile or something but that;s the risk you take and amazon is good at returns. Here is what I got: Power-On Hours: Only 54 hours (practically new!) Power Cycles: 5 (barely used) Bad Sectors: 0 reallocated, 0 pending, 0 uncorrectable Errors: 0 read errors, 0 CRC errors Temperature: 33°C (healthy) enough said

I ordered two of these drives (ST12000NT001). They work very well and are very quiet in a be quiet 802. They do not have the 5-second click that I read WD Black drives have. Unfortunately, one of them died (post-return date). I have spent many hours working with Seagate to get a replacement drive. They have kept trying to send me an IronWolf (non-Pro) drive (ST12000VN0008). I received the first drive and was ready to send it back, but they tried to send another non-Pro drive. Apparently, they are out of stock, so their system wants to downgrade my drive. I even mentioned that Amazon has them in stock if they want to buy one for me. :) It is a great drive when it works, but the return system is rather lacking which can play into the decision to purchase future drives. The people I have spoken with via the support bot have been very nice. The down side is that the system wants to give me a lesser model. If you need to return yours, watch carefully on what the replacement is. Report Card (if Amazon allowed split scores): - Drive: A (when it works) - Support staff: A (very polite and helpful but a bit uninformed by Seagate on how to handle odd cases) - Support system: F (Seagate *really* needs to fix its process, so the correct drive is sent in the first place) Update (2024/2/29): Seagate still cannot find a replacement IronWolf Pro drive to send me. I have spent hours on chat with different people. The last two times I contacted Seagate, I have received the "check back in 48 business hours" after being in a chat for more than two hours. The killer is that they have that unit available on their own website for sale. I have given the support people high ratings each time, yet the "Would you recommend Seagate?" question keeps dropping. I am now dropping my rating here from three to two stars. Update (2024/4/1): It continues. Seagate sent me another incorrect drive. I am currently speaking with support. The best they can do is find an NE001 model even though they have the NT001 models in stock at Amazon and Seagate. They say they can only provide Factory Certified and not new drives under warranty. However, they had plenty of time to refurbish the drive I sent them. I know they cannot just send me back the same drive, but I am very frustrated. Knocking the review down to one star. I doubt I will buy another Seagate drive at this point. It is too much hassle. Update (2024/6/19): A bunch more back and forth has happened. I received another incorrect drive. There was confusion on the status of my RMA. Some thought it was finished probably due to how long the information in the ticket was. Finally, I got in touch with a support person that was able to find the right group above her to handle it. They told me, via her, to keep the incorrect drive, and they would send a new drive. Well, it was another refurbished drive, which is what I expected at the beginning of this, yet it was the correct drive. Checking the warranty on the drive showed it to be only a few months, so I had to contact support again to rectify it. At first, they bumped it to three years. He had me check their site to verify it was correct but was quick to fix it to five years. Seagate should make their own drives easier to differentiate if even their own support can be confused. My head hurts. :) At long last, I have the correct replacement drive. It only took 4 months. Ugh! Update (2024/7/5): Three weeks. That is how long the replacement drive lasted before it crashed. Update (2024/7/30): Not as much difficulty this time, although spent hours on it, another replacement drive is on its way. Update (2024/8/5): The replacement drive was DOA. Of course.

Really happy I bought this for Plex—it's fast, reliable, and easy to use, perfectly compatible with the Ugreen DXP 4800 Plus NAS. No issues so far. It does get somewhat warm, but that's to be expected, and it fits perfectly in the NAS drive bays.

Es primera vez que uso este tipo de disco duros especialmente diseñado para uso de NAS. Algo que notas es cuando la sacas de su caja, por cierto está bien protegido, es lo pesado, literalmente un bloque. En que lo estoy usando en el UGREEN NAS DXP2800 dos disco de 8 TB en configuración RAID 1 -Es rápido el acceso de la información en la cargar y la descarga -Se siente robusto el disco duro en comparación a uno normal -No es muy silencioso cuando se activa el NAS >Te puede parecer costoso en invertir en este tipo de disco duro, pero después de investigar y hablar con un usuario de NAS. Ver que en realidad lo que estoy buscando es confianza y seguridad. En proteger y resguardar información valiosa. Recuerda que es el corazón del NAS! En esto meses ha funcionado muy bien sin problemas.

Got my drives verified from segate, no problem

I am giving for stars mostly for the support I got from Amazon customer service regarding my order. I bought two 12TB drives on the 23rd nov during the sale period. I got them on the 15th Dec. I was traveling during that time, but when I got home, I installed them right away in my brand new NAS. Unfortunately only one worked without a problem. The other one was spinning but was not loading and reading nothing. I tried to put in intro a PC and also a 3.5 sata adapter and connected to a laptop. The same problem-it wasn't readable. Luckly amazon customer service undarstood the problem and gave me a refund. I bought a WD drives this time.

Like all hdd’s, advertised & usable space aren’t the same. So you’ll get 20tb of actual space

I bought 4 of these, 3 were working and 1 spoilt.. i almost returned it but found out i could send to Seagate for RMA to get a replacement.. so i did that as i bought it at a super price.. returning it would mean i'd have to buy another at a much higher price. Overall still happy since i can get a new one from Seagate as they have international warranty. Update 18May'25: i sent in the 12TB to Seagate for RMA, and they sent me a replacement 18TB.. how awesome is that.. :-)

Bom desempenho, silencioso
