On the recent Seam‘s Investor and Analyst Conference, the company unveiled It has delivered limited units of his new 40 TB hard drives based on its Mosaic Hamr platform.
These 40 TB discs use heat-assisted magnetic recording (HAMR) to reach 4 TB per dish over ten dishes, which marks a shift to the Seagate Mozaic 4+ platform.
Although these are not yet available in general, the entire production is planned to start in the first half of 2026 after extensive customer qualification tests.
Next year on a full scale.
“We have already sent 40 Terabyte Engineering samples to our customer. We are planning to initiate Quals next quarter, and we will continue the Quals in 2026, where we will bring a wide part of our customer base to the Mozaic 4 platform,” Dr. John Morris, CTO from Seagate.
Volume -Development depends on how data centers Integrate and validate the discs. However, the aim is to move a significant part of the Seagate Exabyte shipments to Hamr-based disks, which promise a higher capacity and efficiency of data center.
As CEO, Dr. Dave Mosley from: “10 discs would take you to 40 terabytes … This gives better efficiency in the data center. At fleet level this is how our customers think.”
The Seagate long-term plan includes rolling out even larger capacities, including 44 TB discs by 2027 and 50 TB discs by 2028.
The delay of being Original projection 2017 For 50 TB discs, by 2026, the complexity of the scaling of HAMR technology underlines. Nevertheless, the 40 TB development still positions Seagate in the race for the Biggest HDD On the market.
Rival companies follow different strategies. Western Digital (WD) continues to expand the capacity via EPMR and Optinand, so that HAMR is reserved for its Own 40 TB launch expected at the end of 2026.
“Other companies have started taking Hamr with 30 TB HDDs, but we believe that it is true potential of Hamr at 40 TB. Until then we will continue to use technologies such as Optinand and UltrasMr to increase the capacity of existing HDDs to 40 TB,” said Kimihiko Nishio, WD’s manager.
Toshiba, another important player, has developed his technologies, such as magnetic magnetic recording (MAMR).
The company wants to release its first 35 TB HDD based on HAMR before 2026. Toshiba’s strategy includes combining MAMR with future HAMR implementations to achieve these capacities.
These drives will not rely on average consumers who are looking for the Fastest HDD or even the Best HDD For home use, their development is closely linked to the AI-driven cyber security weapon race.
The early shipments of Seagate of 40 TB discs suggest technical leadership in the race to develop the greatest HDD, but the road to commercial reality is winding, and the cautious attitude of competitors implies that the challenges are considerable.
