Seagate IronWolf 4 TB NAS Internal Hard Drive HDD – CMR 3.5 Inch SATA 6 Gb/s 5,400 RPM 256 MB Cache for RAID Network Attached Storage, Rescue Services (ST4000VN006)

I've read a lot of reviews about these IronWolf drives that say they're very noisy. Whilst I've found that some random spin-ups can catch me off-guard whilst in my quiet office, I've found the noise to be tolerable, especially in the case in which it's housed.After running it in before moving data to it, it's performing as expected. I've found speed to also be as expected and haven't experienced any issues whatsoever. I also find it to be value for money compared with its closest competitor, which is typically more expensive. Furthermore, I've had 4 of the competitor's 8TB drives and 1 started having issues within the first two weeks of use so things are looking positive for this drive, which has been going strong for a couple weeks now.

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.

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.

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.

Seagate are a good brand, this drive relaced a failing drive.All my past hdd's have lasted well, using pc's since the 90's most of the drives were seagate.WD also are also a good choice. the price of this drive had gone down in price, hence the Seagate.As for the seller estimate in a week, turned into next day delivery, so 5 stars for that.

One of my Synology NAS devices recently reported a degraded volume due to one of the two failing Seagate hard drives.After much deliberation between WD and Seagate (reading countless reviews and statistics) I decided to stick with Seagate again. The NAS has been running continuously with a pair of standard internal Seagate PC drives (not NAS designated drives) since ordered here on amazon back in Feb 2013. 6 years of continuous Synology operation serving files on my network and recording a surveillance camera feed, bearing in mind these are not NAS designated drives. That was good enough for me. Moreover, the price of the Seagate was better than WD.I received the new drive in minimal cardboard packaging, no bubble wrap - just the usual box-in-box with amazon paper cushioning - so I was a little concerned about potential drops and knocks.Plugged the drive into my PC and began thorough drive tests using Seagate's SeaTools software, ensuring a full surface scan was done. All checks passed without any problems. I checked the drive's SMART attributes and was concerned with some of the RAW data for Read Error Rate and Reallocated Sectors count. Turns out (after a little research) Seagate implements its own HEX raw values to allow them to record both read counts and error counts. In summary, no error, no reallocated sectors for my drive.I have now run the drive in my PC for a few weeks before placing it into my NAS, so far so good. Ran a few benchmark tests using CrystalDiskMark. Results attached (image).Would recommend.

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.
