Seagate IronWolf, 4TB, NAS, Internal Hard Drive, CMR 3.5 Inch, SATA, 6GB/s, 5,900 RPM, 64MB Cache, for RAID Network Attached Storage, 3 year Rescue Services, FFP (ST4000VNZ08)

I purchased this drive to replace a dead Toshiba drive in my Synology NAS. Was worried it wouldn't work alongside the other Toshiba drives, but much to my surprise, it did, and works perfectly to this day. I purchased this about 2 years ago and it's going strong, with very healthy drive status and good performance. I don't get the full capacity though as my other drives are smaller and I have them in hybrid RAID, but that's my configuration rather than a downside to this drive. Very pleased with it and will be purchasing some more to replace the other drives in due course.

This review is for a Seagate Ironwolf 4TB 3.5 inch HDD.First the good stuff.The replacement disk I received is great. It is quiet and smooth. It performs well as part of a raid and has been working 24/7. I expect it to be as good as my other seagate disks. In addition Amazon customer service were great and replaced the original with a new one without quibble. The replacement was delivered promptly, on time and well packaged. The return process was straightforward and without cost to me.But......At the first attempt the disk was delivered to me wrapped in a single-layer bubble wrap packet within an Amazon cardboard packet. It was not delivered on the due date, consequently there was nobody present at the delivery address to receive it. I arrived home to find it behind the garden gate. To be fair to the delivery agent there was no indication on the packet that the contents should be handled wit care. I cannot understand how Amazon can let a delicate and expensive item like this be so poorly packaged.Needless to say it was dead on arrival.Would I buy another from Amazon? Well, actually I did, in order to create a raid. My experience with the other disk was (thankfully) completely different and as good an experience as I could have wished.Please, Amazon, make sure that all hard disks receive careful treatment in future.

I'll start by saying that I've not had much luck with Seagate drives in the past. I tend to stick to Western Digital as I'm yet to see one fail, and I've had bad experiences with Seagate, Toshiba et al. However I needed 4 drives for a NAS and I didn't have much choice. WD red drives now use SMR technology, which is a modern means of magnetically writing the data to the disc. It makes manufacturing cheaper at the expense of performance. Significantly so in fact, to the point where avoiding SMR drives is actively encouraged unless you're archiving data.The Seagate IronWolf drives use the more conventional 'CMR' technology. So with some trepidation I bought 4 of them over the WD Red which ordinarily would have been my first choice.I installed them in a Synology DS418 4-bay NAS enclosure, configured using Synology hybrid raid with a single drive fault tolerance giving me just under 12 terabytes of available storage. The drives have been installed for a few days and so far have performed flawlessly, allowing the Synology to reach gigabit transfer speeds. I will edit the review if they fail within an unexpected timeframe, but so far they are running quietly with very little heat and vibration, and all passed the Synology drive tests. Very pleased.

Now had three of these - first failed after 2 weeks. Bought two to replace it and add more resilience, they've been fine since then. Run slightly warmer than WD Red+ drives, but seem to work fine otherwise.

I use this as secondary storage in my PC, storing files and other things like that, with my OS and games being on an SSD. Overall, it's a great HDD, and it gives me a lot of storage. Do note that as it's designed to be in a NAS, it'll have lower speeds than a PC hard drive, but for file storage and backups it's not an issue at all. Sometimes makes a lot of noise, but wearing headphones it's not too noticeable.

Ordered two of these drives to use in RAID 1 for my NAS. A previous drive had failed and the other was 7 years old so due an upgrade. Both drives arrived in seperate antistatic pouches wrapped in large bubble wrap. They weren't loose enough to bounce around in the box I had, but I beleive a common criticism of Amazon's packagine for hard drives is they can sometimes be too loose in the box which can cause damage. However this wasn't the case for me.The drives have only been in the NAS for just over a week now, both working fine, they don't make that much noise but they are lower rpm drives which isn't a problem for what I use them for. All in all, I' am happy with the purchase.

I ordered two IronWolf 4Tb hard drives to replace a pair of failed Western Digital Red drives in one of my WD MyCloud Mirror NAS enclosures. I chose IronWolf drives because they are CMR drives and the serious failure of my two Western Digital Red drives (which are SMR) caused me grave concern. (I have two more WD MyCloud Mirror servers equipped with Red RAID 1 drives with no failures installed 5 years ago.)The two IronWolf drives were easy to install and configure in my NAS bay. I was immediately impressed with their very quiet operation compared to the Red drives and look forward to a long term life.But I’ve learnt a very important lesson when running servers in a RAID 1 configuration. I had believed that RAID 1 is the safe configuration for saving critical data. But I now realise that when one RAID 1 drive fails the other RAID 1 drive has a much higher likelihood of failure because of increased rate of read/writes and constant attempts to restore damaged data. This is what happened to me – one drive raised an alert of impaired health, and the other drive failed very quickly afterwards. I just managed to transfer my valuable data to another drive before losing both drives completely.So even with a RAID 1 configuration in a NAS enclosure, it is wise to routinely backup to another drive!

Bought 3 and a half years ago for use in a home NAS for music and photo storage. Still going strong with no sign of giving up!
