- Seagates Hamr – Rimpling could deliver 150 TB hard drives – but not until 2035
- Mozaic -Platform now enables 4TB plates that pave the way to 10 TB -De -Disks in 2028
- Mozaic 4 to send in 2026 while Mozaic 5 is aiming towards the end of 2027
On Seagate’s recent 2025 investor and analyst conference, CEO dr. Dave Mosley and CTO Dr. John Morris the company’s long -term timetable for hard -draginnovation.
This suggested the option of 150 TB hard drives, Biggest HDD ever at groundbreaking 15 TB plates, but warned that this milestone will remain at least a decade away.
The basis for this future lies in Seagate’s Hamr (heat -assisted magnetic recording) technology currently implemented through the company’s Mozaian platform.
10TB per Fad on track in 2028
“We have great confidence in our product roadmap through Mozaic 5. And in particular, the design room for granular iron platinum media, which is in Mozaic 3, sees very viable to get us up to 10 terabytes per disk,” Dr. Morris
The fact that 10TB-per-disk-bonchmark is expected to be reached in 2028. ”We trust that we can give a path to 10 terabytes per disk in about this timeframe,” Morris added, explaining that spin-stand demonstrations of new technologies typically take five years to reach product qualification.
Looking beyond 10TB, Seagate examines how to expand the capabilities of its iron platinum media.
“We believe there is another level of expansion of the granular Iron Platinum architecture that could theoretically become as high as 15 terabytes per disk,”
Such a performance would pave the way for 150 TB hard drives by stacking 10 plates per day. Unit. However, he warned, “in addition to 15 terabytes per disk requires a certain level of disturbing innovation.”
Seagate’s CEO, Dave Mosley, repeated this long-range vision and noticed, “We now know how we can get to 4 and 5 and beyond. In fact, we have visibility … In addition to 10 terabyte disk with Hamr technology.”
“It will not be easy, but I am convinced that it will keep us on a competitive cost course that no other technology will replace in the next decade, probably beyond.”
The company’s trust is supported by the latest milestones. Mozaic 3, which delivers 3TB per FAD, is now in volume production, and Mozaic 4 (4TB per dish) 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 is targeted at 5TB per year. Pad, scheduled for customer qualification at the end of 2027 or early 2028.
Still, Seagate made it clear that 150 TB drives, based on 15 TB plates, are not imminent. As Morris emphasized, “This is only another element of the work we are doing to support our strategy … It will take time. There is still a lot of work ahead of us to get there.”
