Seagate IronWolf Pro, 12 TB, NAS Internal Hard Drive, CMR 3.5 Inch, SATA 6 Gb/s 7,200 RPM, 256 MB Cache, for RAID Network Attached Storage, 3 years Rescue Services, FFP (ST12000NE0008)

I've had the drive in my Ugreen NAS a month now without issue. The warranty was showing as 6 months initially,but the seller promptly provided an invoice, and seagate amended it to 5 years.

It is worth emphasising that these drives are specifically designed for installation in a NAS or storage server. The vibration sensors enable them to work better when there are multiple spinning drives in use all alongside each other, 24x7. The chance of in-life failure is small and the Pro version of Ironwolf means that you have a higher workload rate limit and a five-year warranty plus three-years of data recovery service. You should be using them with some kind of data redundancy such as RAID 5 or better. Don't forget the 3-2-1 rule for backup: at least 3 copies of the data, on two different physical devices, one of which is off-site. If you get a working hard drive, it's excellent. I'd give it five stars, really. After about a month, I have two of these 16TB Ironwolf Pro drives running in my NAS and will probably buy another if/when my storage requirements need it. With a working drive, plugging it into the NAS and making use of it should take less than five minutes. As with all makes of NAS drives, noise levels are noticeable when the NAS is busy, but they are almost silent when just spinning. Apparently (unlike some of the existing single-starred commentaries for this product), one cannot make remarks about the quality of enclosure of the delicate product for its apparently very bumpy voyage down the big river to me, or about the level of effort and time that it takes to deal with the practical and financial consequences, twice. My overall marking reflects the chances of me buying another one the same way.

They work well in my ugreen dxp2800.

Has the capacity but is very noisy in operation.

Good genuine hard drive. What more is there to say?

Initially thought there was something wrong with my sata ports not reading the disk but come to find the Flash drive ID was ST4000DM000-1F21 a Barracuda disk not ST4000VN006-3CW1 an Ironwolf disk. It has an Ironwolf label on it so it looks legit. I am reviewing the disk I bought from Salmik Creations, this is verified and on record. Extremely disappointed.

Happy buying this reliable HDD for my NAS

Does what it says on the tin works well at a good price
