Seagate’s Game-Changing 30 TB+ Hard Drives Revolutionize Storage, Paving the Way for Industry Transformation


January 22, 2024 by our News Team

Seagate launches Mozaic 3+ hard drive platform with innovative HAMR technology, doubling capacity and reducing costs for data centers and other markets.

  • Unparalleled areal densities of 3 TB+ per platter, with plans to achieve 4 TB+ and 5 TB+ per platter in the future
  • Allows customers to store more data in the same floor space, effectively doubling capacity compared to conventional drives
  • Uses similar material components as traditional hard drives while dramatically increasing capacity, resulting in lower storage acquisition and operational costs


Seagate, a leader in mass-data storage solutions, has announced the launch of the Mozaic 3+ hard drive platform, which incorporates their innovative Heat-Assisted Magnetic Recording (HAMR) technology. This launch marks a significant milestone in the storage industry, as it enables unparalleled areal densities of 3 TB+ per platter, with plans to achieve 4 TB+ and 5 TB+ per platter in the future.

The Mozaic 3+ platform powers Seagate’s flagship Exos product family, with capacity points of 30 TB and beyond. These high-capacity products are already shipping in volume to hyperscale cloud customers. The platform addresses common pain points in the industry by allowing customers to store more data in the same floor space, effectively doubling capacity compared to conventional drives.

One of the key advantages of Mozaic 3+ is that it uses similar material components as traditional hard drives while dramatically increasing capacity. This allows data centers to lower storage acquisition and operational costs, including a 40% improvement in per terabyte power consumption. Additionally, the platform helps customers achieve sustainability goals by offering a 55% reduction in embodied carbon per terabyte.

Seagate is experiencing strong demand from data center customers, and a leading cloud service provider is focused on ramping up the adoption of Mozaic 3+. Seagate’s CEO, Dave Mosley, emphasized the importance of areal density in accommodating the growing need for storing massive amounts of data.

The Mozaic 3+ platform incorporates several industry-first innovations, including Superlattice Platinum-Alloy Media, Plasmonic Writer, Gen 7 Spintronic Reader, and a 12nm Integrated Controller. These technologies enable precise data writing, reliable data storage, and efficient data reading.

John Rydning, Research Vice President at IDC Global DataSphere, highlighted the significance of Seagate’s areal density breakthrough in expanding the installed base of hard drive-based mass storage.

In addition to data centers, Mozaic 3+ storage technology will have applications in enterprise, edge, NAS, and video and imaging markets.

Technology Explained


NAS: Network Attached Storage (NAS) is a specialized storage device or server that provides centralized data storage and access over a network, usually using Ethernet connections. NAS systems are designed to offer a convenient and efficient way to store and share files among multiple users or devices within a home or office environment. Unlike traditional storage solutions, NAS devices operate independently and have their own operating systems and management interfaces. They are characterized by easy setup and configuration, making them accessible even to users with limited technical expertise. NAS devices can offer various features, including data redundancy through RAID configurations, remote access over the internet, automatic backup, media streaming, and even application hosting in some advanced models. As a versatile and user-friendly storage solution, NAS has become a popular choice for both personal and small business use.
