• Seagate’s HAMR roadmap could deliver 150TB hard drives - but not before 2035
• Mozaic platform now enables 4TB platters, paving the way to 10TB disks by 2028
• Mozaic 4 to ship in 2026, while Mozaic 5 aims for late 2027 qualifications

At Seagate’s recent 2025 Investor and Analyst Conference, CEO Dr. Dave Mosley and CTO Dr. John Morris outlined the company’s long-term roadmap for hard drive innovation.

This hinted at the possibility of 150TB hard drives, the largest HDD ever, by groundbreaking 15TB platters, but cautioned that this milestone remains at least a decade away.

The foundation of this future lies in Seagate’s HAMR (Heat-Assisted Magnetic Recording) technology, currently being deployed through the company’s Mozaic platform.

10TB per platter on track for 2028

“We have high confidence in our product roadmap through Mozaic 5. And notably, the design space for granular iron platinum media that's in Mozaic 3 looks very viable to get us up to 10 terabytes per disk,” said Dr. Morris

That 10TB-per-disk benchmark is expected to be reached by 2028. “We do have confidence that we can provide a path to 10 terabytes per disk in roughly this time frame,” Morris added, explaining that spin-stand demonstrations of new technologies typically take five years to reach product qualification.

Looking beyond 10TB, Seagate is exploring how to extend the capabilities of its Iron Platinum media.

“We believe that there's another level of extension of that granular iron platinum architecture that could theoretically get as high as 15 terabytes per disk,”

Such an achievement would pave the way for 150TB hard drives by stacking 10 platters per unit. However, he warned, “beyond 15 terabytes per disk is going to require some level of disruptive innovation.”

Seagate’s CEO, Dave Mosley, echoed this long-range vision, noting, “We now know how we can get to 4 and 5 and beyond. As a matter of fact, we have visibility... beyond 10 terabytes of disk with the HAMR technology.”

“It’s not going to be easy, but I’m convinced that’s going to keep us on a competitive cost trajectory that no other technology is going to supplant in the next decade, probably beyond.”

The company’s confidence is backed by recent milestones. Mozaic 3, which delivers 3TB per platter, is now in volume production, and Mozaic 4 (4TB per platter) is scheduled to enter customer qualification next quarter.

Seagate expects to begin volume shipments of Mozaic 4 drives in the first half of 2026. Meanwhile, Mozaic 5, targeting 5TB per platter, is planned for customer qualification in late 2027 or early 2028.

Still, Seagate made it clear that 150TB drives based on 15TB platters are not imminent. As Morris emphasized, “This is just one other element in the work that we do to underpin our strategy... it will take time. There’s still a lot of work in front of us to get there.”

• Details of two HMD smartwatches have emerged
• Both wearables are said to be running Wear OS
• One of the models comes with a 2MP camera attached

It appears we may soon get a couple of new contenders for our best smartwatches list. HMD (perhaps best known for releasing Nokia-branded phones in recent years) is rumored to be working on two smartwatches, both running Wear OS, and with a camera fitted to one of them.

This comes from tipster @smashx_60 (via Notebookcheck), and while we can't guarantee the accuracy of the claim, smartwatches would be a sensible next step for HMD – which already makes phones, tablets, earbuds, and the HMD OffGrid.

According to the leak, the first smartwatch will be the HMD Rubber 1, with a 1.85-inch OLED screen, a 400 mAh battery, and heart rate and spO2 tracking. There's also, apparently, a 2-megapixel camera on board this model.

Then there's the HMD Rubber 1S, which comes with a smaller 1.07-inch OLED display, a smaller 290 mAh battery, and no camera – though the heart rate and SpO2 tracking features are still included. It sounds as though this will be the cheaper choice.

For adults or kids?

HMD RUBBER 1- oled 1.85" display - 5ATM Waterproof - BT5.3, WiFi, NFC, Accelerometer, heart rate, SpO2- 2MP CAM- Wear OS- 400mAh, USB-C, QiHMD RUBBER 1S- oled 1.07" - 5ATM Waterproof - BT5.0, WiFi, Accelerometer, heart rate, SpO2- Wear OS- 290mAh, USB-C, QiMay 29, 2025

The camera on the HMD Rubber 1 is interesting, as this would be something we haven't seen on a Wear OS watch before. While it's not clear how the camera would be integrated, presumably it would allow photos and videos to be captured from your wrist, with or without a phone connected.

There's some speculation in the Notebookcheck article that these smartwatches may be intended for kids to use, rather than adults – something along the lines of the Samsung Galaxy Watch for Kids that launched at the start of the year, perhaps.

The leak also mentions that these smartwatches will come with 5 ATM waterproofing, which is good for depths of up to 50 meters. That suggests they'll have a relatively robust casing around the internal components.

We'll have to wait and see what HMD might have in store, though as yet there's been nothing official from the company. In the meantime, we're patiently waiting for the arrival of Wear OS 6, which is expected to be pushed out in the next month or two.

In our list of the best streaming services we crowned Paramount+ as the best platform for classic movies, and it still is – however, it's broadening its library of 21st century features in its list of new titles for June 2025.

With over 80 new movies landing on June 1, among the list of new Paramount+ movies lies modern titles that over time have earned modern classic status, starting with No Country for Old Men (2007) – a western thriller from the Coen brothers starring Javier Bardem and Josh Brolin.

But that's not all and, if anything, the drama never ends. Joining the Coens' thriller is Steve McQueen's Best Picture winner 12 Years a Slave (2013), Tarantino's Pulp Fiction (1994), and four movies from the Indiana Jones franchise. The thrills are endless.
