Seagate (Recertified) 12TB IronWolf NAS SATA Hard Drive 6Gb/s 256MB Cache 3.5-Inch Internal Hard Drive for NAS Servers, Personal Cloud Storage (ST12000VN0007)

Have to say, for what it is, it hasn't failed me yet! Bought 2 years ag, keeps running! Of course not the fastest but man, the storage! Definitely recommend!

I was initially skeptical about using a recertified 12TB hard drive in my NAS, but after testing in a RAID10 configuration, I’m pleasantly surprised by its performance.Cost Savings: Compared to new drives, the price was significantly lower, making it a budget-friendly option for high-capacity storage.Performance: Speeds are on par with new drives—no noticeable bottlenecks in read/write operations. Running in RAID10, I’m getting a good balance of speed and redundancy.Low Power Consumption & Noise: The drive runs quietly and doesn’t generate excessive heat, which is essential for 24/7 NAS operation.For NAS users looking for an affordable way to expand storage, a recertified 12TB drive is a solid option—So far, it’s performing well in my RAID10 setup, but I’d still recommend having a backup strategy in place just in case.Would I buy another? Yes, but only for non-critical data or in a redundant RAID array.

I bought one of these for Time Machine backups. Initially, all seemed well. The drive formatted properly and I did a 1TB Time Machine backup. On attempting to back up a second computer (also 1TB), I encountered an endless cycle of the drive randomly unmounting and backups failing. I ran Disk Utility and got a report that the disk had FAILED Disk First Aid. I finally decided to completely reformat the drive. It would not reformat. I repeated several cycles of trying to reformat and running Disk First Aid. All ended in failure.On trying to order a replacement drive, I encountered one of the least helpful Customer Service representatives ever! Every time I asked a question, I got a long period of silence. On asking the question again, I'd get silence - sometimes followed by an answer. The representative's speech was at times difficult to understand.The return process was byzantine. All of the information I initially entered the first time (when initiating the process) had to be entered again. Then I was given a URL and told to check back in 48 hours.I don't know whether this mess was because I was dealing with Seagate Customer Service or a much-degraded Amazon customer service, but the process itself seemed broken.This drive was supposed to be a Data Center quality NAS drive with 1 MILLION HOURS mean time before failure.I had the drive exactly 2 months (~1440 hours) before it irretrievably failed (and actually was having problems with it for the past month ~720hours). So did I get a lemon? Or is the 1,000,000H MTBF figure a lie?

This review is for the "Seagate 12TB IronWolf NAS SATA 6Gb/s NCQ 256MB Cache 3.5-Inch Internal Hard Drive", I ordered on prime day and received it 2 days later, I have made copies of data from one HDD to another so after a format I tried to copy the data of my old (but reliable 8TB HDD) to this one. Almost immediately I notice a clicking noise in an otherwise silent (in between clicks) of the new HDD, I re-check everything, check connections, tightened everything and the clicking stop and proceeded to copy and that is when the fun started, the copy of the files went a healthy amount of mbps to zero every so often, I did not remember having an issue like that ever before but I google possible reasons and I found a few here and there saying that I partition the drive wrong, to change the size of the sectors, that I purchased the wrong drive for my kind of use etc, so I started again, partitioned and format it and went again to copy but same thing happened so I returned and 5 days later I got a replacement which is working now with flying colors and no funky behavior. So to anybody that is having a similar issue I say.. Just return it, you have a bad drive.After the initial experience I may say that I like this drive, it is SILENT which bring assurance of no issues. I recommend it if you are in the market for one.

Best of the best!Speeds are as advertised, much quieter than other drivers, size is as advertised, works great and the quality is amazing for recertified!Edit: I'm coming back to say that the drives that I received must be brand new, because they are running flawlessly. I wanted to add that I purchased my drives from ServerPartDeals (Formerly Tech on Tech) and I trust them with my life! Also, come to find out, Linus from LinusTechTips uses ServerPartDeals for their refurbished and recertified drives! They made a video about them as well.They're an amazing company and very trustworthy! Thanks for the perfect drives!

So 1 don’t buy this product from smart global. Idk what there game is but it’s not kosher.2. The box that I received clearly had what was inside the box on the outside of the box. ( which is against all standard practices ! ) Would Apple send out the new iPhone in a box that says “ NEW IPHONE STEAL ME?” On the outside packaging ? No they would not.3. Confirm factory recertified not seller. Which means been through more testing then a normal hdd from seagate.4. Through usb 3 getting the rates of 240mbps which is as expected.I’m using a Cenemate dual bay / raid das. No loud noises nothing. Quiet as a humming bird.Oh also packing inside was horrible. Loose disk drive inside cardboard box. Def not happy about that. If it didn’t take 3 weeks from order date to get this I would have refused it. But we shall see !Took a star off for seller incompetence which really shouldn’t effect product but more of the overall experience !

When dealing with large amounts of media, backing up can be insane. I deal with about 60TB of media a year and there is no raid solution that costs less than my car to do the job. I have a docking station, and buy two of these at a clip. I use Hedge to make a redundant backup of my projects and move on knowing I'm protected. I have 40 of these drives now. That's 20 redundant backups of 12TB each. That would require a 250TB raid... price compare that. These are great and keep me protected.

I got 2 of these to use in my Synology DS418 NAS. They've work great, and I haven't had any problems. I do notice a slight whine sometimes, which concerns me a bit, but they still seem to function fine. As with all HDDs the actual capacity is less then the advertised size; the larger the drive, the bigger the discrepancy. These are advertised as 12TB, but you'll only get 10.82TB of usable space out of them. It's disappointing to "lose" 1TB+, but par for the course.These were pricey ($400 apiece when I bought them), but since my NAS only has 4 slots, I wanted to maximize the capacity per slot, and these were the largest drives I could find at the time.
