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)

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.

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!

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?

These drives came well packaged and checked out as certified Seagate drives. The storage capacity is perfect for my NAS needs as the raid 1 configuration leaves me with 10.8Tb usable storage. The only problem that I ran into was that they are not on Synologys compatibility list. The 12TB seagate ironwolf drive on their has a model number ending in 008 while these end in 007. The only problem this causes, other than an install error message, is that the full feature set of my NAS isn't avaliable. It's not a deal breaker though. They still set up and work well.

I have always stayed away from "recertified" electronics, especially hard drives but this time I had to try them. The price was crazy cheap for 12TB drives so I bought 5 of them for my NAS device. These drives were listed as compatible with my model NAS by the NAS manufacturer so I installed them and they are running perfectly. They're quiet and fast. I am very pleased with this purchase!

I bought one of these drives to replace and back up all of my older hard drives that were varying degrees of full (3x 4TB, 1x 3TB, 1x 1TB). On that front, this drive has been fantastic. To have everything in one place and not have to go back and forth between drives and try to keep track of which one has what thins on it is an incredible quality of life improvement. And the value for the storage size is just unbeatable, coming in at something like 3 cents per gigabyte is an insane drop from the 7-14 cents that my older drives were at the time. That said, it is definitely worth noting that this drive is much, much louder than not just any one of my old hard drives, but all of my old drives put together running at the same time. All of the drives are mounted in the same metal drive bays that have minimal rubber grommets to help 'reduce vibration'. This drive makes audible clicking and whirring noises when it is in use. Audible over 10 fans running in the computer and with the case roughly 8 feet away from my chair. The older drives you could very faintly hear when they first spin up from being powered down, but then couldn't hear them at all once they were spinning. It might just be that I got a loud one, but otherwise, I just can't imagine having 4+ of these things running in a RAID/NAS unless it's in a different room.

The drive works but puts out a decent amount of heat and makes a loud noise. Seems to be completely fine otherwise and in a proper case it's not even worth mentioning, but it does make me feel uneasy.

The size and quality of this drive is great, and an incredible value for the price. S.M.A.R.T. showed that it'd hardly been used before I bought it. I've had it in a ZFS raid for a lot time now and it hasn't had a single error show up in SMART and hasn't had any file corruption show up in ZFS scrub. Highly recommend for anyone looking for a RAID drive
