BREAKING: Toshiba has just announced plans to launch a groundbreaking 40TB HDD by 2027, utilizing innovative 12-disk stacking technology and Microwave-Assisted Magnetic Recording (MAMR). This development comes as Seagate is already testing its own 40TB HAMR drives, raising questions about Toshiba’s timing in a rapidly evolving data storage market.
The urgency of this announcement lies in the competitive landscape of hard drives. Seagate is expected to release its 44TB models right when Toshiba’s drives are set to hit the market, potentially leaving Toshiba struggling to catch up. Seagate has been at the forefront of storage technology, having shipped limited units of its 40TB HDDs earlier this year, based on its Mozaic HAMR platform.
In a recent Investor and Analyst Conference, Seagate CEO Dr. Dave Mosley confirmed that their ten-disk configuration offers superior efficiency for data centers, establishing a strong foundation for the company’s future roadmap. The full-scale production of these high-capacity drives is slated to begin in the first half of 2026.
Toshiba’s new design, which incorporates two additional disks compared to earlier models, aims to deliver high-density storage without compromising stability. The use of glass substrates instead of aluminum allows for thinner platters and enhanced durability, potentially increasing storage density significantly.
“Our goal is to provide data centers with larger capacities while maintaining a lower total cost of ownership (TCO) as data demands continue to grow,” a Toshiba spokesperson stated.
Despite these advancements, Toshiba’s timeline raises concerns among industry experts. By the time their drives become available, Seagate plans to progress to 50TB drives by 2028, leaving Toshiba to play catch-up in a market that values speed and innovation.
As data storage needs surge, the race for higher capacity drives is becoming increasingly critical. The competition between Toshiba and Seagate highlights not only the technological advancements in hard drive design but also the pressing demand from data centers for larger and more efficient storage solutions.
