This is the first time I have ever purchased recertified hard drives. So far I have successfully added them to my NAS and they are functioning as they should. Long term is what really matters in this case. Time will tell.

Even though this says recertified, a check showed it as having less than a few minutes of powered on time. I used it in my Synology NAS for expanding storage. A SMART check after installation showed everything working great, and I've been using it for several weeks now with no issue! I'd definitely consider a recertified again!

It works perfect for nas

Bought two of these drives. Running them on a UGREEN NAS. Have been great so far, only 3-4 days in, but will update if any issues.

Meine Erfahrung nach etlichen dieser Platten bisher:Ein Ausfall nach kurzer Zeit, den der Verkäufer auch korrekt abwickelte.Preislich unschlagbar und für die erwartende Restlebensdauer auch ok.Steige allerdings jetzt langsam auf neuere MG9 um.

Est installé dans un nas, tourne depuis plus de 1 an H24 et est parfaitement fonctionnel a ce jour.

Ich habe vier davon in ein Synology NAS gestellt. Raid 5 plus eine Hot-Swap wenn notwendig.Das Ganze läuft jetzt seit einigen Monaten stabil und zuverlässig ohne die geringsten Probleme.Über Synology Drive kann man von allen Betriebssystemen (Mac, Linux und diese andere, seltsame Zeugs mit dem Backslash) zugreifen. Und ich habe alles da, wo es sein soll.Mehr Speicherplatz brauche ich nie wieder. Moment, hat das nicht Bill Gates auch mal gesagt? Ach das war RAM ;-)

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

Ordered 3 18s to try out in my new NAS. Read the past reviews. My 3 were individually boxed and packaged as if I picked them up from the local Best Buy.Then upon inspection; I looked around for scratches and dents. I looked for the finest of scratches from being in a NAS previous.Nothing!!! I got more scratches from sliding one drive in and out than any of these had.Bought directly from Seagate; dents ad scratches. But they worked.These refinished ones were so good and so quiet; I ordered 2 more after 30 minutes with these 3.The other two will be here in 3 days.Very, very satisfied!! Will be picking up another 5 next month!!

The box arrived pretty beat-up but each individual drive was extremely well packaged. I ordered 4 drives for a new NAS. These are refurbished and the external condition is "like new". No issues installing them in the NAS. They have only been running for about a week but no issues so far.

Purchased two 10TB Ironwolf Pro HDD drives. Nowhere in the description did I see they were refurbished. In fact I only found this out when I decided to write this review and read the description on the feedback page, which is different from the website description. Unfortunately I am long past the return date.Shipment took almost a month to arrive so I had already found replacements and put these on the shelf as backups.Another concern I originally had is they arrived without any cushioning, they were simply loose in the shipping box. Not a safe way to handle a hard drive.Today I attempted to put them in service. Drive one was DOA, not recognized or seen by Disk Management . Drive two, also DOA, creates a screeching sound like a metal lathe. On inspection I found a dent in the top of the disk.This is a complaint about the seller “Network-Wholesale.” Misleading Advertising, extremely slow shipping and poor packaging.

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 & PerformanceWith 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 & ValueAs 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 OptimizationThe 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 ManagementIn 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 setups7,200 RPM and 256MB cache provide fast data access and transfer speedsOptimized for NAS with AgileArray firmware and vibration toleranceAffordable pricing for recertified enterprise-grade storageHigh 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 unitGenerates some heat, so good NAS ventilation is recommendedVerdict: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.
