Seagate's massive, 30TB, $600 hard drives are now available for anyone to buy
For more than two decades, hard drive manufacturer Seagate has been experimenting with heat-assisted magnetic recording (HAMR) technology for increasing hard drive density -- drives that use tiny lasers to heat up and expand parts of the drive platter, write data, and then shut off to allow the platter to cool and contract, all within less than a nanosecond. After decades of overly rosy availability predictions, Seagate announced in late 2024 that it was finally delivering HAMR-based drives with capacities of up to 36TB to some datacenter customers. Today, the drives are finally available for end users and individual IT administrators to buy, albeit only in smaller capacities for now. Seagate and other retailers will sell you massive 30TB IronWolf Pro and Exos M hard drives for $600, and 28TB drives for $570. Both drives use conventional magnetic recording (CMR) technology, which performs better than the shingled magnetic recording (SMR) technology sometimes used to increase disk density. The drives are based on Seagate's Mosaic 3+ platform, which "incorporates Seagate's unique implementation of HAMR to deliver mass-capacity storage at unprecedented areal densities of 3TB per disk and beyond." Seagate's press release is focused mostly on the large drives' suitability for AI-related data storage -- "AI" is mentioned in the body text 21 times, and it's not a long release. But obviously, they'll be useful for any kind of storage where you need as many TB as possible to fit into as small a space as possible. Although most consumer PCs have moved away from hard drives with spinning platters, they still provide the best storage-per-gigabyte for huge data centers where ultra-fast performance isn't necessary. Huge data center SSDs are also available but at much higher prices. Seagate competitor Western Digital says that its first HAMR-based drives are due in 2027, though it has managed to reach 32TB using SMR technology. Toshiba is testing HAMR drives and has said it will sample some drives for testing in 2025, but it hasn't committed to a timeline for public availability.

Seagate unveils 30TB HDDs for the masses -- laser-powered HAMR drives are now widely available
Today, Seagate introduced its Exos M 30TB and IronWolf Pro 30TB hard disk drives (HDDs), which utilize heat-assisted magnetic recording technology. This technology employs a laser to increase storage density. This is the first time Seagate has made HAMR HDDs based on its Mozaic 3+ technology available to the mass market, marking a significant milestone for both the company and the storage industry, which unleashes an unprecedented amount of storage density. Seagate has also shared its in-depth performance benchmarking, which we've shared and analyzed below, highlighting strong performance trends for the new HAMR drives. Seagate's 30TB and 28TB versions of the Exos M and IronWolf Pro hard drives are now officially available globally through the Seagate online store and through the company's network of approved resellers and distribution partners. Let's take a deeper look at the drives and Seagate's benchmarks. Seagate's Exos M 30TB and 28TB, as well as IronWolf Pro 30TB and 28TB hard drives, are built on the company's Mosaic 3+ platform, which represents Seagate's second-generation implementation of HAMR (heat-assisted magnetic recording). Unlike the first generation, which never reached the market, Mosaic 3+ is now commercially available. To enable high-density writing, the drives are equipped with a specialized plasmonic writer subsystem featuring a vertically integrated nanophotonic laser. This laser heats a small spot on the FePT recording layer on the disk to approximately 450°C (842°F), altering its magnetic coercivity and allowing data to be recorded on the heated spot. Reading is handled by heads that use Gen 7 Spintronic Reader, which features multiple reading sensors to help mitigate signal interference between adjacent tracks, ensuring data can be read accurately even at very high track densities. The new 30TB HDDs come in the industry-standard 3.5-inch form factor and operate at a rotational speed of 7,200 RPM, which is standard for enterprise-class performance hard drives to balance performance and power consumption. Yet, for those clients who need to alter consumption, Seagate's PowerChoice adjusts idle power consumption and PowerBalance technology enables balancing power consumption and IOPS (input/output operations per second) performance. Additionally, the drives are equipped with a 512 MB multi-segmented cache. This multi-part buffer helps smooth data transfers and enhances performance during intensive read/write operations, particularly under burst workloads. Speaking of performance, the drives feature 3TB platters with a rather unprecedented areal density, offering a maximum sustained transfer rate of 275 MB/s, approximately 5 MB/s higher than previous-generation drives. As for random performance, the HDDs are rated for up to 170/350 random read/write IOPS (4K, QD16), down from 170/550 random read/write IOPS in the case of the Exos X18 HDDs from a few years ago. Although Seagate's Exos M 30TB and IronWolf Pro 30TB have many similarities, they are formally designed for different applications. The former is designed for large-scale deployments in cloud and enterprise environments (specifically those used for AI), so it comes with numerous design enhancements to improve reliability and ensure predictable performance in highly-vibration environments, such as a top and bottom attached motor, RV sensors, and other means to reduce turbulence. By contrast, the latter are designed for use in NAS systems within commercial and enterprise environments, so the drive fully supports continuous operation in multi-bay and multi-user setups and is built to handle the stresses of modern workloads. Seagate's new Exos M 30TB and IronWold Pro 30TB are the first HAMR-based HDDs that will be available in channel and retail markets, as previously the company only shipped such drives to select hyperscale customers who had qualified them beforehand. Being available to a broader range of clients is clearly a significant milestone for Seagate. Both of Seagate's 30TB HDDs utilize conventional magnetic recording (CMR), ensuring compatibility with standard storage systems while increasing capacity. This tech also preserves as much performance as possible, unlike Shingled Magnetic Recording (SMR) technology. In addition, the drives use a SATA 6 Gbps interface and consume 6.9W (average) - 9.5W (maximum), so they are drop-in compatible with existing storage systems, assuming that they can handle 30TB HDDs (which may not be the case with all NAS, for example). A modern 4U storage server can accommodate up to 100 3.5-inch HDDs; thus, a fully equipped machine with Seagate's 30TB HDDs can store up to 3,000TB of data (3PB). Thus, the new hard drives enable the storage of from 30PB (42U rack) to 36PB (48U rack) per single rack, which is unprecedented storage density. However, while Seagate's 30TB drives indeed increase capacity and storage density, they still offer roughly the same amount of performance as their predecessors, so the increased density doesn't come at the cost of performance in the most important types of workloads for HDDs. Below we have some of the performance tests conducted by Seagate, with the mixed workload results showing a clear advantage and highlighting the performance tuning for real-world applications. The sequential read/write bandwidth (128 KiB, Queue 1) benchmark shows that both the Exos M 30TB and the Exos X24 achieve nearly identical peak read and write speeds, around 275 MB/s on the outer tracks. This indicates that the increased platter density in the Exos M does not compromise large-block sequential throughput. From a throughput-per-spindle perspective, both drives perform equally well, suggesting that Seagate maintained read/write head performance while increasing capacity. In the 4 KiB random read benchmark at a queue depth of 16, the Exos M 30TB delivers roughly 350 IOPS, closely matching the Exos X24. Despite narrower tracks due to the denser media, the Exos M sustains equivalent read performance, implying that Seagate's TDMR-based read heads effectively maintain signal quality and accuracy. This confirms that small-block read I/O does not degrade with the transition to HAMR and higher areal density. However, the 4 KiB random write performance reveals the only notable weakness in the Exos M, as it trails the Exos X24 significantly, achieving only about 170 IOPS at the same queue depth. This drop is consistent with known limitations of HAMR, such as more complex write calibration, which affects short-duration, high-frequency write operations. Nonetheless, the performance penalty appears specific to small-block writes, which is visible in this synthetic test but may not be noticeable in real-world workloads. Also, keep in mind that nearline HDDs (such as the Exos M) are not exactly designed for small random writes -- SSDs or caching mechanisms step in to satisfy those types of workloads, even in consumer NAS. In the mixed-workload benchmark, which combines 128 KiB random writes (Q1) and 4 KiB random reads (Q16) with the write cache disabled, the Exos M demonstrates a clear advantage. It doubles the read IOPS of the X24 and shows reduced 99.9th percentile read latency. This suggests that the Exos M's architecture, specifically its segmented 512 MB cache and optimized read path, handles concurrent I/O more efficiently. This also clearly shows that Seagate has prioritized tuning for real-world hard drive usage scenarios. What is perhaps more important is that sequential performance-per-TB and random performance-per-TB of the new HAMR-based 30TB HDDs are significantly lower compared to HDDs from several years back, but that is a natural and expected byproduct of the increased capacity. As a result, companies using these hard drives will mitigate this per-TB performance drop to maintain the quality of service in their data centers, often by augmenting the deployments with strategically placed flash-based caches. Seagate's 30TB and 28TB versions of the Exos M and IronWolf Pro hard drives are now officially available globally through the Seagate online store and through the company's network of approved resellers and distribution partners. The listed retail prices are $599.99 for both the Exos M 30TB and IronWolf Pro 30TB models, and $569.99 for the 28TB variants of each drive.

Seagate rolls out 30 TB HAMR drives for AI storage demand
Exos and IronWolf drives show spinning rust isn't going anywhere Seagate has released two 30 TB hard drives based on its HAMR technology, pitching them as more energy efficient cheaper options for datacenter operators dealing with AI workloads. The hard drive maker today confirmed global channel availability of Exos M 30 TB and IronWolf Pro 30 TB units. The devices take Seagate to within the touching distance of rvials' products: Western Digital launched HDDs with up to 32 TB in a single unit late last year, and Toshiba has demonstrated similar capacities. Seagate itself sampled a 36 TB drive in January, claiming it has a roadmap to 100 TB. The two new models effectively top out Seagate's respective ranges aimed at datacenter and NAS applications for now, and are built on its Mozaic 3+ tech that uses heat-assisted magnetic recording (HAMR). This uses a laser to heat where data is written, allowing data bits to be packed more densely. Seagate is pushing AI as the reason why these ever larger drive capacities are required, forcing enterprises to up their on-prem storage. A similar trend is happening at the network edge to support inferencing closer to the user, the company says. All this means, according to Seagate, that spinning hard drives still have a place in the datacenter where customers are mindful of costs when storing large volumes of data. This is a point Seagate was keen to drive home last year, in a presentation that sought to rebut flash vendor Pure Storage's claims that flash-based SSD prices per terabyte would soon match those of hard disk drives. Ed Burns, IDC Research Director for Hard Disk Drive and Storage Technologies, was happy to reinforce this point in a supportive quote. "While not often associated with performance such as low latency, the highest capacity HDDs are a critical strategic asset in the AI development process, filling the need for mass capacity storage of the foundational data essential to building and improving the highest quality AI models in the market today and into the future." Only last year, Seagate and the other big disk drive makers blamed AI for causing a hike in prices, citing rising demand for high-capacity products. This had taken the manufacturers by surprise after they had cut production as much as 20 percent in the preceding, post-pandemic years. Seagate listed UK prices for the two new drives, which it says are available now through its online store as well as resellers and distributors. The Exos M 30 TB is listed at £498.99 ($670), while the IronWolf Pro 30 TB is £559.99 ($753). ®

Seagate brings HAMR to market with new 30TB Exos and IronWolf Pro drives
Serving tech enthusiasts for over 25 years. TechSpot means tech analysis and advice you can trust. This Is Huge: A couple of years after first announcing its new magnetic storage platform, Mozaic 3+, Seagate is now ready to mass-market its first commercial HAMR-based HDDs. According to the storage specialist, hard disk drives are here to stay - especially as AI technologies demand massive amounts of storage to support the data-hungry needs of modern large language models and generative systems. Seagate has officially announced global availability of its first high-capacity hard disk drives based on HAMR technology, targeting the mass-market storage segment. The new 30TB Exos M and IronWolf Pro HDDs are built on the Mozaic 3+ platform, the branding Seagate adopted for its first HAMR-powered drives to reach retail shelves. The US company has made substantial investments in heat-assisted magnetic recording (HAMR) technology, which promises major gains in both data density and drive reliability. HAMR works by using a laser diode embedded in the drive's read/write heads to briefly heat a tiny area of the recording medium. This highly localized heating, which occurs in less than a nanosecond, allows for much greater data density when storing digital bits. Seagate first introduced the Mozaic 3+ platform in 2024, publishing a dedicated product page by the end of that year. In early 2025, the company began sampling its first 36TB HAMR drives to select customers for testing and validation. CEO Dave Mosley revealed that engineers had already achieved an areal density of 6TB per platter in lab conditions, with plans to push that figure to 10TB per platter in future iterations. Seagate now expects to produce 100TB hard drives by 2030, driven by advancements in HAMR and other cutting-edge recording technologies. As part of the announcement of its new 30TB Exos M and IronWolf Pro drives, the company emphasized that the unprecedented surge in AI infrastructure investment is expected to dramatically increase demand for high-capacity storage solutions. According to Seagate's SVP of Edge Storage and Services, Melyssa Banda, trends like data gravity and the rise of hybrid cloud are shifting network focus - and, by extension, storage needs - toward edge computing. Currently, around 90 percent of the world's digital data is stored in just 10 countries, but nearly 150 countries are moving toward implementing local data residency requirements. Seagate says the Mozaic 3+ platform was built to meet and exceed these evolving demands. The new Exos M and IronWolf Pro drives, available through Seagate's store and authorized resellers, offer capacities of up to 30TB. Both models use conventional magnetic recording technology, which delivers more consistent input/output performance compared to SMR-based drives. The Exos M is designed for enterprise-grade storage deployments, while the IronWolf Pro targets 24/7 NAS environments in RAID configurations. Pricing for the 30TB models is set at $600, while the 28TB versions are priced at $570 - well within expectations for users with extreme storage needs.

Seagate unveils massive 30 terabyte HAMR-powered hard drives
Good lord, what are you even going to do with that much storage? Dont' worry, it's not for you, it's for AI. Of course it is. Human beings have a hard time dealing with numbers that get really big. The speed of light, the number of atoms in apparently small amounts of matter, the energy being burned every time you ask ChatGPT how many days there are in July. It doesn't really fit into our meat brains. Take, for example, Seagate's latest industrial hard drive, which holds 30 terabytes of data. Oof. The new Exos M and IronWolf Pro are the most dense drives single I've ever seen in the standard form factor, narrowly beating out existing 28TB models by leveraging Seagate's innovative Heat-Assisted Magnetic Recording (HAMR) technology. But these hard drives aren't really designed for regular PC users -- they're being made for the data center market, as demand for scalable storage spikes in the AI industry. That said, there's nothing stopping you from just rolling up to Seagate's digital storefront and putting your money down. The new drives, in the standard 3.5-inch form factor, cost $600. (Editorial note: It's entirely possible that 30TB drives have been available before in the 3.5-inch form factor, and I know NAS systems with more than that spread over multiple drives are a thing. This is the first time I'm seeing it with a regular link to buy, as far as I'm aware.) Again, it's hard for me to imagine what I'd do with that much storage. My first desktop PC that I didn't have to share with my sister had a 40GB drive, and my parents thought that was beyond the dreams of avarice. I have hundreds and hundreds of games in my Steam account, some of which teeter beyond the 100GB mark, and I still don't think I could fill up a 30TB hard drive with all of them. In college a friend of mine who definitely, absolutely was not me, allegedly, once shared a little over 2TB of video files on the local campus network, and that was the top score in a student population of over 40,000. But these things aren't meant for individual users, unless those individual users are hosting some rather impressive websites from a home server or doing some other exotic stuff. These drives are meant to be bought dozens or hundreds at a time, and installed in data centers that cost billions of dollars to set up. I haven't seen a new laptop with a spinning hard drive in years, and even desktop users with space to spare are now transitioning to full solid state storage more often than not. Still, I can't deny that there's something tempting about buying one and seeing if I could fill it up. I wonder how many hi-res Skyrim textures it would take...

HAMR technology, which Seagate has been developing for over two decades, employs tiny lasers to heat and expand parts of the drive platter momentarily. This process allows for writing data at higher densities than conventional methods. The Mosaic 3+ platform incorporates a specialized plasmonic writer subsystem with a vertically integrated nanophotonic laser, heating a small spot on the FePt recording layer to approximately 450°C (842°F) 2.
The new 30TB HDDs operate at 7,200 RPM and feature a 512 MB multi-segmented cache. They offer a maximum sustained transfer rate of 275 MB/s, slightly higher than previous-generation drives. Random performance is rated at up to 170/350 random read/write IOPS (4K, QD16) 2.

Both the Exos M and IronWolf Pro models use conventional magnetic recording (CMR) technology, ensuring compatibility with standard storage systems while preserving performance. They utilize a SATA 6 Gbps interface and consume 6.4W (average) to 9W (maximum) 24.
Seagate is positioning these drives primarily for AI-related data storage and large-scale deployments in cloud and enterprise environments. The Exos M is designed for enterprise-grade storage, while the IronWolf Pro targets 24/7 NAS environments in RAID configurations 14.
Pricing for the 30TB models is set at $600, with 28TB versions available at $570. This pricing is considered competitive for users with extreme storage needs 45.
The release of these drives marks a significant milestone for both Seagate and the storage industry. It brings unprecedented storage density to the mass market, with a single 4U storage server now capable of storing up to 3,000TB (3PB) of data 23.
Seagate's CEO, Dave Mosley, has revealed that the company's engineers have already achieved an areal density of 6TB per platter in lab conditions, with plans to push that figure to 10TB per platter in future iterations. The company expects to produce 100TB hard drives by 2030 4.
Seagate emphasizes that the surge in AI infrastructure investment is expected to dramatically increase demand for high-capacity storage solutions. Trends like data gravity and the rise of hybrid cloud are shifting network focus toward edge computing, with nearly 150 countries moving toward implementing local data residency requirements 4.
