- CEGAT quietly drives 40TB Hamr, determines speed for next storage
- Mozaic Hamr Tech Crams 4TB per plater, promise to promote massive storage efficiency
- The data center expansion will determine how fast these record-breaking 40TB drives hit the mainstream
Recently at Seigate’s Investors and Analyst Conference, the company revealed It has distributed limited units of its new 40TB hard drives based on its Mozaic Hamr platform.
These 40TB drive segate’s mojic 4+ uses heat-assisted magnetic recording (HAMR) to obtain 4TB per plater in ten platters, marking a change towards 4+ platforms.
Although these are not yet widely available, but the comprehensive customer has been slated to start full scale production in the first half of 2026 after testing.
Full scale production starting next year
“We have sent samples of 40 terabyte engineering already limited to our customer. We plan to start a quail in the next quarter, and we will continue Quals in 2026, where we are bringing a wide part of our customer base to Mozaic 4 platforms,” Dr. John Morris, CTO of Seigate said.
The readiness of the volume will depend on how data centers integrate and validate the drive. However, the target is to transfer an important part of the Xbyte shipment of the seagate to the HAMR-based drive, which promises high capacity and data center efficiency.
As CEO, Dr. Dave Mosley explained, “10 discs will deliver you to 40 terabytes … This gives better ability to the data center. At the level of the fleet, how do our customers think.”
The long -term plan of the seagate also includes to include large abilities, including 44TB drives by 2027 and 50TB drives by 2028.
Delay from its original 2017 launch for 50TB drive by 2026 underlines the complications of scaling to HAMR technology. Nevertheless, the development of 40TB is still in the race position to offer the largest HDD on the market.
Republic companies are following various strategies. Western Digital (WD) continues to expand the capacity via EPMR and Optinand, by burning HAMR for its 40TB launch expected at the end of 2026.
“Other companies have started adopting HAMR with 30TB HDDs, but we believe that the actual capacity of HAMR starts at 40TB. Till then, we will continue to use technologies like Optinand and UltrasMR, which is to increase the capacity of the current HDD to 40TB,” said WD’s sales manager Kimiko Shikshiyo in Japan.
Another leading player Toshiba is developing his technologies, such as microwave-assured magnetic recording (MAMR).
The company aims to release its first 35TB HDD on the basis of HAMR before 2026. Toshiba’s strategy involves a combination of mamr with future HAMR implementation to achieve these capabilities.
These drives will not appeal to average consumers in search of the fastest HDD or even the best HDD for home use, their development is closely linked to the AI-operated cyber security weapons race.
Early shipments of seagate of 40TB drives suggest technical leadership in the race to develop the largest HDD, but the path of commercial reality is winding, and the alert stance of the contestants means that the challenges are enough.
