Mozaic 3+
Where the Future Is Read and Written
Superlattice Platinum-Alloy Media
A storage layer with higher magnetic coercivity than that found in conventional drives.
Plasmonic Writer
Heats and writes the media to over 800º F and cools it back down in less than two nanoseconds.
Gen 7 Spintronic Reader
Ensures that data can be read accurately after write, and read swiftly at ultra-high areal densities.
12nm Integrated Controller
Built for data mobility and data integrity, the controller meets increasing data demands.

Foreseeing a data deluge on the horizon, our team broke through the barriers of possibility. Harnessing the potential of heat-assisted magnetic recording (HAMR) for substantial areal density gains, we dedicated two decades to perfecting the process, culminating in the groundbreaking Mozaic 3+ platform.
Fueled by HAMR, the Mozaic platform transforms data bits, packing them tighter while keeping things magnetically and thermally steady. Meaning, you can store far more data on each disk while enjoying performance and reliability that’s rock-solid as ever.
All while using the same material resources, and the same trusty 3.5-inch form factor.
And the countless exabytes it will inevitably generate.
The world's largest data centers choose mass-capacity hard drives to store 90% of their data.1
Amounting to massive TCO savings.
Mozaic-integrated hard drives enable data centers to:
And enables data centers to deliver on sustainability goals.
Seagate’s Mozaic 3+ is more than a technological advance—it’s a promise to sustain the inexorable growth of the digital universe.
And we’re just getting started.
What Is Mozaic 3+, How Does It Work, and What Can It Do for My Data Center?
Seagate's Mozaic 3+ white paper details a breakthrough in data storage, featuring HAMR technology for unparalleled areal density per disk, enabling future-ready, high-capacity hard drives.
