Seagate IronWolf 8TB review: There are good reasons that Seagate is still selling this internal NAS drive, but none are its price

There are bound to be many people reading this review and wondering why something that should have been covered a decade ago has resurfaced on our site.

And, it is true that Seagate launched the IronWolf 8TB model in 2016, hardware that is hardly considered current in 2026.

But this review isn’t covering the mechanism that Seagate launched then, the ST8000VN0022, thankfully. Instead, it is the one that came after that in 2019, the ST8000VN004.

For complete transparency, they released a newer option, the ST8000VN002, in 2021, but during my review, I’ll explain the differences and why you might want one over the other.

OK, I accept that this model has been around for 8 years, almost, but we’re exceptionally busy here at Tech Radar Pro, and we get to things eventually.

The fundamentals of the 8TB IronWolf have been remarkably stable across the past decade. Every generation has used CMR recording, which matters. IronWolf drives feature CMR technology and AgileArray firmware, ensuring smooth RAID performance, reduced vibration, and efficient power management. The 180TB per year workload rating, the RV sensors, the three-year warranty, and the bundled Rescue Data Recovery Services have all persisted as defining features of the consumer tier.

The EHA (European Hardware Awards) named the Seagate IronWolf portfolio Best Hard Drive for 2025, which suggests the brand has maintained its reputation well.

However, there is one significant blot on this landscape, and that’s the price increases that this drive, and others have experienced in the past six months.

An IronWolf 8TB costs about 95% more than it did in 2025, depending on the region it is sourced from, and prices still show an upward trend. Admittedly, this isn’t as bad as the price increases we’ve seen in memory and SSDs, where some items have quadrupled in cost, but it’s a shock to a market that expected cost reductions over time.

Is it the right time to buy Seagate IronWolf drives? That depends on how flexible you are about timescales, and if you believe that the AI crash is just around the corner or that the price pad today will be a fraction of where it might end up going. Whichever side of that line you fall, there was probably a better time that has since passed.

Seagate IronWolf 8TB NAS drive: Price

You can’t get the ST8000VN004 on the Seagate site, but the company still makes it, and it can be found on Amazon (and other online retailers) for $299.99 on Amazon.com, or £283.94 on Amazon.co.uk. The price across the rest of Europe is €317 via Amazon.

To put that in perspective, in October of 2025, the same drive would cost you £145 in the UK, making it 95% more expensive in just a few months.

But Seagate’s competitors have pulled the same rug up under their customers, with the Western Digital 8TB WD Red Plus being $314.99, and the Toshiba N300 8TB NAS is close to $400.

The only cheap alternative I’ve seen is from a brand called MDD or MaxDigitalData, which sells an 8TB drive for $238.95, but I have no experience with this brand.

Excluding that option, Seagate is the cheapest option for 8TB 7200rpm NAS drives.

However, if we break down the current Seagate IronWolf drives, there is an important trend that we need to understand. As a side note, I’ve not included one of the 10TB models, since these don’t seem to be readily available at this time. All these prices are from Amazon, but you might get a better deal elsewhere.

As you can see, based on cost per TB, the most expensive IronWolf or IronWolf Pro are the 4TB capacities, and the sweet spot is the 12TB IronWolf. The 8TB IronWolf isn’t a bargain, but it's cheaper than the IronWolf Pro 8TB. Counterintuitively, the larger the drives get, up to 24TB, the cost goes down per TB.

Where things get weird is with the larger IronWolf models, as they approach their 18TB zenith. Due to poor availability, the 16TB IronWolf costs the same as the 16TB IronWolf Pro, and the 18TB model is actually more expensive.

Seagate IronWolf 8TB NAS drive: Design

As a reviewer of hard drives for at least the past thirty years or more, one of the critical selling points that makers often highlighted was the number of platters and heads.

And some brands still detail this in their product overviews, but Seagate does not.

Part of this coyness is down to the maker wanting to change the number of platters in existing product lines without generating a user backlash.

However, as storage technology has advanced, which allows for greater data density on each platter, the makers can reduce cost (and increase profit) by reducing the number of platters but retaining the same total drive capacity.

Curiously, the 8TB IronWolf is a classic example of this in action.

The first version in 2016, the ST8000VN0022, had six platters and twelve heads, at roughly 1.33TB per platter. Then came the ST8000VN004 that replaced it, which I believe had five platters and ten heads, which works out to 1.6TB per platter.

And finally, in 2021, the ST8000VN002 arrived, and it is suspected that it has just four platters, making each 2TB.

Note that the N004 is a 7200 rpm drive, whereas the more recent N002 is a 5400 rpm unit. They both use CMR recording technology, have the same 256MB of cache, and have a 3-year warranty. But the N004 uses 7.8W of power in operation, where the N002 uses less than half of that at 3.4W.

The faster rotation speed does translate into some extra transfer speed, 210MB/s versus 202MB/s, but even in an array with up to eight disks, that extra performance still doesn’t justify the extra power consumption for a system running 24/7. And, since power generally turns into heat, a system using the N002 drives might run cooler, too.

Seagate IronWolf 8TB NAS drive: Understanding the price hikes

As I mentioned at the start of this review, prices for all hard drives, not just NAS-specific ones, have increased in the past six months. Why is that?

• AI Data Centre Demands
• Supply Constraints
• Component Shortages
• Production priorities

Clearly, the biggest impact is being felt on those drives and drive types that are used in an AI data centre. Which is slightly odd, because while many companies have laid out ambitious plans to build massive gigawatt-consuming AI facilities, the number of these that have actually been built, or even broken ground, is remarkably small.

So, where did all the hard drives from the channel go? Mostly into warehousing, where they’re being held for the companies with the big plans. Some have gone into data archival solutions created by major cloud suppliers, expecting a huge increase in demand, but most are sitting waiting for AI to call them to action. For the drive makers, the idea that all this pre-sold stock might suddenly end up back in the channel if the AI bubble bursts must be a truly terrifying one.

While it doesn’t impact the 8TB model covered here, drives above this one, 10TB and up, are impacted by shortages in helium supply, which is necessary for high-capacity drives, and has hampered production output.

What has exacerbated the situation is that, wishing to cash in on the AI boom, drive makers have focused more heavily on the larger capacities, all of which need helium to work.

Prior to the AI era, there was a general transition underway from physical hard drives to SSDs. But since SSDs are now stupidly expensive, that has propelled system builders back towards the humble HDD, increasing demand.

Reacting to this, drive makers have focused on data centre, enterprise, and high-capacity consumer drives (IronWolf/EXOS), which are being prioritised, leading to shortages of general consumer models. And, in the context of the wider market, drives like the IronWolf 8TB are considered both business and consumer, further increasing demand for them.

In short, this is a perfect commercial storm in which market forces are aggressively driving prices, and the outlook is uncertain.

If it's ever been the right time to shop around, then this is it. Or, wait out the storm and hope that the AI bubble bursts and releases lots of stock into the market, forcing prices down.

For anyone working on a major NAS or server deployment in the near future, this news is not positive.

Seagate IronWolf 8TB NAS drive: Final verdict

The IronWolf ST8000VN004 is a mature, well-understood drive at this point. The core technology is not new, but that is not necessarily a weakness. CMR reliability at 8TB is proven, the compatibility list with NAS vendors is extensive, and Seagate's IHM integration is now embedded across most major platforms, including Synology and QNAP.

For home users or small businesses, the IronWolf 8TB is an option, but its 12TB brother offers better value. If you specifically want 8TB drives, then use the 5400rpm ST8000VN002 instead. It’s technically a little slower, but it has half the power consumption, impacting the cost of ownership.

But there might be better alternatives with higher-capacity drives, where the overall spend on drives isn’t substantially different.

Let’s imagine we have a six-bay NAS, and the plan is to use RAID 5 with a hot-swap drive ready to handle any failure. Using 8TB drives that would give 24TB of usable space and would cost approximately $1800 in drive expenditure.

Switching to 12TB drives, getting 24TB of usable capacity under RAID 5 requires only three drives, and even with a hot spare available, you have two free bays and a total outlay of $1644. And, some additional savings could be made on the NAS, getting a four-bay model.

There is an argument that an array with five active drives will perform better than one with three, and it will. But many NAS use SSDs for caching, and unless you use 10GbE networking, the roughly 630MB/s that the 12TB drives can shift won’t seem slower than the 1000MB/s that the 8TB could transfer.

Internally, there might be a difference in transfers, but to LAN-connected users, the performance benefit of having more drives in the array isn’t apparent. There is also good logic that the more drives you have, the greater the statistical chance that one of them will fail, though smaller drives also lead to a faster rebuild in the event of a drive failure.

So would I buy the 8TB IronWolf? Neither model has a compelling argument at these price points. There is a better argument for the 12TB, or the Pro 12TB.

My concern is that because people are spending company money in many cases, they’ll just pay what drive makers are asking, encouraging them to make even fewer drives, forcing prices even higher. Eventually, the businesses currently reaping massive profits (like Samsung and Micron) will cook their golden goose completely, if they haven't already
