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.
