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.

Great, easy to install. I have loads of space now for all my media projects.

This hard drive works well and was a good value for the money. I had no problem hooking it up to my computer. I really don't hear the drive noise very much after startup. I would definitely recommend this drive to anyone who needed mass storage for movies or even games.

Great value for the money and they worked perfectly. However they are louder than average.

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?

So far no issues with it. I was skeptical with it being refurbished but works great.

So far so good. I ran an extended self-test out of the box and it came back perfect. I've been running it for about a week, so it's still early to talk about reliability, but so far it's pretty quiet and it's quick enough for me. Great price for a lot of storage.
