- Seagate’s Hamr Roadmap 150TB can distribute hard drive – but not before 2035
- Mozaic platform now enables 4TB platters, paves the route of 10TB disc by 2028
- Mozaic 4 to Ship in 2026, while Mozaic 5 is purified for qualification at the end of 2027
At the recent 2025 investor and analyst conference of Seigate, CEO Dr. Dave Mosley and CTO Dr. John Morris Underlined the company’s long -term roadmap For hard drive innovation.
This indicates the possibility of 150TB hard drive, By groundbreaking 15TB platers, the largest HDD, but warned that this milestone stays at least a decade away.
The foundation of this future lies in seagate’s HAMR (heat-assisted magnetic recording) technology, which is currently being deployed through the company’s Mozaic platform.
10TB per plater on track for 2028
Dr. “We have high confidence in our product roadmap through Mozaic 5,” Morris said. And in particular, the space for granular iron platinum media in Mozaic 3 is very viable to get us up to 10 terabytes per disk, “Dr. Morris said.
Morris said it is expected to reach 10TB-Per-Disk Benchmark 2028. “We are confident that we can provide a path to about 10 terabytes per disc in this deadline,” Morris stated that spin-stand performances of new techniques usually take five years to reach product qualifications.
Looking ahead of 10TB, Seagate is finding out how to increase the abilities of your iron platinum media.
“We believe that there is another level of expansion of that granular iron platinum architecture that can theoretically achieve as high as 15 terabytes,”
Such an achievement will pave the way for 150TB hard drive by stacking 10 platers per unit. However, he warned, “Some levels of disruptive innovation are required beyond 15 terabytes per disc.”
Seeing this long -distance vision, Dave Mosley, CEO of Segate,, we now know how we can get 4 and 5 more than that. As a matter of fact, we have visibility … beyond 10 terabytes of discs with us technology. “
“It’s not going to be easy, but I am sure it is going to put us on a competitive cost projection that there is no other technology in the next decade, perhaps beyond.”
The company’s confidence is supported by recent milestones. Mozaic 3, which saves 3TB per plater, is now in volume production, and mozaic 4 (4TB per plater) is determined to enter the customer qualification in the next quarter.
Seagate is expected to start volume shipments of Mojic 4 drives in the first half of 2026. Meanwhile, the Mozaic 5, targeting 5TB per plater, is planned for customer qualification at the end of 2027 or in early 2028.
Nevertheless, Seigate made it clear that 150TB drives based on 15TB platters are not adjacent. As Morris insisted, “This is the only other element in the work we do to reduce our strategy … it will take time. We still have a lot of work to reach there.”
