SeagateIronWolf 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)

The Seagate IronWolf 12TB is a fantastic drive for my NAS! It’s fast, reliable, and built for 24/7 operation. Setup was seamless, and performance has been excellent—quiet, cool, and with great read/write speeds. Perfect for large backups, media storage, and file sharing. The built-in vibration protection is a great bonus for multi-drive setups. Highly recommended for NAS users!

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.

These drives arrived a lot quicker than I was expecting which was a welcome change from most retailers, so thanks for that. They have a good reputation but you don't know until your had them for a while, which I haven't. As far as the sound from the two drives, it's not that bad but I do have a dehumidifier in the room as well which is far loader, but you should expect some noise as that's how they work, spinning drives will do that. I have installed them in the new TerraMaster F4-242, which I'm still trying to get my head around but it will take some time, for me to get the benefit of them. Thank You for the excellent delivery and the first-class product.

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 4 of these drives is a Synology DS918+ NAS, they have proved to be reliable. The long warrantee is a bonus and inspires confidence. They are a bit noisy during heavy workloads but I don't find it a problem.
