You’ll never need storage again with this Seagate-demoed HDD that can potentially reach 240TB

Any PC enthusiast will attest to the omnipresent problem of having an ever-growing backlog. Most of the time, not even multiple uber-convenient SSDs can alleviate this issue. Luckily, Seagate may have just come up with a solution that ensures you won’t experience any PC storage space-related struggles in the future.

Research team members from Seagate Technology, Tohoku University in Japan, and NIMS recently demonstrated the capabilities of heat-assisted magnetic recording (HAMR) technology (via Tom’s Hardware) and how it can potentially double the storage capacity of current-generation storage devices. With the biggest HDD offering currently being Seagate’s Exos X Mozaic 3+ 30TB, the new HAMR tech would be able to increase the maximum to 60TB, followed by 120TB a few years down the line, and, eventually, even 240TB. But let’s not get ahead of ourselves.

240TB Seagate HDD is still a ways off from being feasible

Even though HAMR technology displays a ton of potential in bringing the HDD back into mainstream relevance, there are still several obstacles preventing it from actually being feasible. Not only would this sort of device be costly to make, but it would also require a ton of design tweaks and hardware that would undoubtedly push it to a price tag that may be impractical for most. Of course, Seagate, Tohoku University, and NIMS haven’t actually revealed when this potentially 240TB HDD could be released. So, with this in mind, it may still be a ways off from actually being fully developed, let alone sold to the public.

That said, if you’re itching to give your PC a much-needed storage boost, we’ve still got you covered. Take a look at the best NVMe SSD in 2025 so you’ll no longer have any PC space-related problems.
