SeagateIronWolf ST12000VN0008 - Hard drive - 12 TB - internal - 3.5" - SATA 6Gb/s - 7200 rpm - buffer: 256 MB Mechanical Hard Disk

I've been using the IronWolfs and Pros for a number of years now and would highly recommend. They are rock solid and good performers. Super trustworthy and great price for this capacity. They run pretty quiet and cool.

Perfect working on NAS, but on the beginning was little bit woried when I see how they was packed by amazon. puting drives to paper bag it's big mistake in my opinion.

Purchased three specifically for a NAS unit. They are plug and play, work as expected.One driver developed a fault pretty early on. It started making grinding noises and after a couple of days died completely. Amazon were very good and sent me a replacement straight away. Before I returned it I also checked the serial number on Seagate website which indicated that the drive was under warranty so that would have been another option if Amazon hadn't replaced it.Edit: Three months later and 2 of the 3 drives have failed. The first one was replaced by Amazon with overnight shipping - top notch customer service as always. The second one unfortunately was outside the 30 day window and I was referred to the manufacturer Seagate. They were happy to accept it for replacement however they refused to cover shipping costs and I had to pay to return it to Seagate. They also would not dispatch a replacement device to me until they received the faulty one so I was left without a running drive. I eventually received a replacement approximately 7 days later which was NOT a brand new device but in fact a refurbished device! Absolutely appalling customer service. I don't know whether other manufacturers are any better but I will not be taking a chance with Seagate again.

Delivery was prompt and arrived, exactly as expected.Purchased this external hard drive to use in my recently purchased Synology NAS to store photos and videos on. It was very simple to install and set up, even for a tech novice like me.So far, has proved reliable and quick. Plus, the 12tb is more than enough storage to last me for now.NAS is a 2 Bay drive so I will be purchasing a second as a backup drive to this original. Will probably wait till it's on offer though to ensure I get the best value.

I bought this to replace the failed NAS drive from another brand recently, of which i have had failures over the last couple of years, i have now had it in the NAS for a while and i am happy with it, so far it is compatible with the competitor drives and i like that it is CMR technology with a decent cache.I will replace the other drives as they fail with this drive as i like it. I have not yet had it long enough to tell reliability however.

My 2TB Western Digital Red drive started having issues in my Synology Diskstation after running constantly for the last 11 years. I was pretty happy with how the WD Red had performed, so I was going to buy the same again, but in a bigger capacity.However, after reading a few reviews, it became apparent to me that WD were now cutting costs by using SMR technolgy in their drives, basically making them unsuitable for NAS use. Hence my purchase of this Seagate Ironwolf 4TB drive.I went for the basic Ironwolf model, as despite it being slower than the other slightly more expensive Ironwolf models, the slowness also means a slower spin speed & in theory, a quieter disk. My NAS box is located under the TV in my lounge, so I would not appreciate any high pitched whistling being emitted from the disk. I can confirm that my disk is silent in use & is actually quieter than the WD disk it replaced.

Bought two to replace Western Digital Reds that had reached six years old. The extra space is good and the Seagate drive checking software is impressive and very welcome. Think carefully about buying if the NAS is somewhere you can hear it, as there are pretty loud drives; plenty of whirring and clicking as the heads move about.If silence is essential, go Western Digital Red.

I have bought a mountain of drives in my life, the delivery on this was really good it came a day before it was suposed to, however the cardboard box although designed well has no styrafoam or soft padding, im sure a drop of the box or a hard bump would easily damage the drive, othersie the ox was in good shape, its jsut the drive it doenst have all the paperwork you normally get with some drives, the build is good and it looks like a genuine drive, at the price I got it for on the spring sale I was concerned it was a knock off, the drive is very quite in my nas untill you put strain on it then it souns like most drives, if not a little bit moer quite, speed good as it says on the box
