Seagate reveals new breakthrough in HDD technology in the form of new Mozaic 3+ platform

Seagate has revealed a new platform called the Mozaic 3+ that will be powering its flagship Exos family of products for more capacities or volumes per drive. Incorporated with the renowned Heat-Assisted Magnetic Recording (HAMR) technology, as of right now, Seagate is capable of achieving 3TB+ per platter which is already cutting-edge levels of volume but they are also closing in for the 4TB+ and 5TB+ per platter in the coming years through this areal density innovation. There's actually more than just HAMR but several new designs and choices to make Mozaic 3+ work, these include:

• Superlattice Platinum-Alloy Media - High-fidelity data inscription through enhanced magnetic stability
• Plasmonic Writer - Ultra-precise laser that powers HAMR on a fundamental level
• Gen 7 Spintronic Reader - Industry's smallest and most sensitive magnetic field sensor enabling higher data densities
• 12nm Integrated Controller - The heart of the drive itself that provides unparalleled signal processing and noise optimization

For some easy comparison, those who are running a conventional perpendicular magnetic recording (PMR) drive at the typical 16TB capacity will be able to achieve double the storage by swapping to an Exos 30TB Mozaic 3+ technology drive. Aside from the improved ratio of "capacity vs footprint", Mozaic 3+ drives are better in terms of operational cost as well which is an up to 40% improvement in power consumption rate per TB. They are also 55% better in terms of embodied carbon per TB. As such, data center customers are currently under the qualification process for Mozaic 3+ and will soon ramp up volume scaling.
