The Seagate IronWolf Pro 18TB (Recertified) Enterprise NAS HDD offers high-capacity storage and reliability, especially suited for NAS setups and enterprise environments where durability is essential. Here’s a breakdown of its performance, durability, and overall value as a recertified drive: Storage Capacity & Performance With an impressive 18TB of storage, this drive is perfect for handling large data volumes, making it ideal for users who need high-capacity storage in RAID or NAS configurations. The drive operates at 7,200 RPM and has a 256MB cache, ensuring smooth performance and quick data access speeds for backups, streaming, and large file transfers. It handles workloads up to 300TB per year, which is well-suited for heavy-duty use in small to medium businesses or creative setups. Recertified Quality & Value As a recertified product, this IronWolf Pro comes at a more affordable price point than a brand-new unit. Seagate’s recertification process gives a level of assurance, but potential buyers should still consider the balance of cost savings against longevity expectations. While recertified drives often meet quality standards, there is an element of risk in terms of lifespan. Fortunately, the warranty (typically around one year) provides some peace of mind. Reliability & NAS Optimization The IronWolf Pro series is known for its durability and NAS-optimized firmware, making it resilient in multi-bay environments where continuous operation is required. This drive supports Seagate’s AgileArray firmware, designed specifically for NAS use, providing stable performance, RAID optimization, and vibration tolerance in multi-drive setups. However, as a recertified drive, it may be slightly more susceptible to wear over time than a new drive, but for most NAS applications, it should hold up well if used within recommended parameters. Noise & Heat Management In terms of noise, the IronWolf Pro is relatively quiet, especially given its enterprise-grade capabilities. It does generate some heat, which is expected for a drive of this size and speed, so adequate ventilation in your NAS setup is recommended. For home office use, the sound levels are manageable, and in a server environment, they would likely go unnoticed. Pros: Massive 18TB storage capacity, perfect for NAS and RAID setups 7,200 RPM and 256MB cache provide fast data access and transfer speeds Optimized for NAS with AgileArray firmware and vibration tolerance Affordable pricing for recertified enterprise-grade storage High endurance for continuous operation (300TB/year workload rating) Cons: Limited warranty compared to new drives (usually around one year) Some risk of reduced lifespan as a recertified unit Generates some heat, so good NAS ventilation is recommended Verdict: The Seagate IronWolf Pro 18TB (Recertified) Enterprise NAS HDD is a solid choice for those looking to maximize storage capacity at a lower cost. It performs well in NAS environments, thanks to NAS-optimized firmware and robust performance, while its recertified status makes it more affordable for budget-conscious users. While there’s a minor risk in longevity compared to a new drive, the IronWolf Pro’s durability and high capacity make it an excellent solution for both business and personal NAS needs. If you need enterprise-grade storage without breaking the bank, this recertified drive offers strong value and performance.

I was nervous about storing 18TB on a single drive. That is a lot of data that could get lost with a drive failure. So I bought 2 instead. They are running in a RAID 1 software array and seem to work great. Unless I am doing a bunch of disk I/O, such at transferring ~18TB to it, I do not notice much noise. Technically, I get about 16TB of useable space, but that is expected with overhead, filesystem and how it counts each GB (1000MB vs 1024MB). It is still larger than my 6TB x4 RAID-10 array this was replacing. Overall, it seems to be running well.

Nice buy, all actualized nicely and is a quality drive.

Installed into QNAP NAS, 4-drive RAID 5 array. Installed fine, drive looked to be zero-errors. Migrated and expanded storage pool onto this drive. Everything worked fine for two days. Then one morning, I heard a loud clicking noise coming from the NAS, like hard drive access reads but much louder and like something was wrong. Then NAS informed me the drive failed. Tried rebooting, pulling drive and accessing elsewhere, restoring RAID, etc. Nothing works. Fatal error on drive. Sounds almost like the read/access arm broke or something. Will be sending this back and buying only new drives from here on out. This was my first 'renewed' drive purchase and the risk failed. Luckily no data was lost.

I bought five of these to upgrade my NAS. I was able to upgrade myself from four terabyte drives to these new 18 terabyte drives. They all reported zero hours of powered on time and they all seem to have good performance.

i got 5, 18TB Ironwolf Pro NAS refurb drives (Model ST18000NT001 2023 model) for the NAS and so far they run great! tested all 5 and initially got uptime hours of 5,6,12,16 and 26 hours. so barely used units. they all run good, tested with no errors on short and long S.M.A.R.T. tests and no unusual audible noises. there is the normal boot-up clicking initially and you can hear them but some people make these things seem like your living next to an airport and they arent that loud. if you run a fan in the room you wont hear them. they do however run kind of hot. i got temp warnings while creating a raid pool in unraid and they were pushing 125 degrees. so i stuck a fan infront of them and they are at 99 degrees. the system booted right up and saw each drive. didnt have to make any motherboard configuratiuons. all in all a good hard drive so far. will update if anything else happens.

Looks like I was very lucky here. After seeing some reviews of bad drives, etc. I was concerned. I got my drive in 1 day, was shipped from a local warehouse here in the Indianapolis area. Put drive in my Synology 5 disk array. Opened up details after installing and it showed 0 hours used. So, at least in this case, looks like I got a drive that was never used but was sent back to seller for a reason not related to repairs. Rebuilt my 40TB raid array with no issues. Ran full SMART test. No errors at all. Running very quiet and running at similar temperatures to my other 4 drives in system. Very happy with drive, will buy others when I need to upgrade one of my 8tb drives in system.

I was a bit skeptical with a refurbished drive. I'm running 3 10TB Iron wolf's and have a spare, so I gave this on a shot. Been running a month now on my NAS with no issues.

Packaging was excellent. I bought 4 and put them in a Mediasonic PROBOX 4 Bay 3.5” SATA Hard Drive Enclosure It all running tickety boo!

Great price and you cant go wrong with Seagate in terms of warranty.

Llevo un año con él y 0 problemas. Capacidad inmensa, lo que esperaba. 100% recomendado

Sono mesi che sta girando instancabile, super valido

Versand war super. Top verpackt ohne das es auch nur die Chance hatte zu wackeln. Die NAS HDD wurde auch ohne Probleme erkannt, läuft 1A. So bin ich einfach nur absolut Zufrieden! :)
