Seagate, a leading provider of data storage solutions has announced the launch of the Exos 30 TB hard drive, which is the largest and most advanced hard drive on the market. The Exos 30 TB hard drive uses Mozaic 3+ technologies, which combine heat-assisted magnetic recording (HAMR), plasmonic writer, spintronic reader, and RISC-V controller to achieve unprecedented areal density and performance.
The Exos 30 TB hard drive is designed for artificial intelligence (AI) and cloud data centers that need to store massive amounts of data in a limited space and with lower power consumption.
Seagate claims that the Exos 30 TB hard drive can store more than 1000 Blu-ray movies and offers a 40% improvement in per terabyte power consumption and a 55% reduction in embodied carbon per terabyte compared to a conventional 16 TB hard drive.
The Exos 30 TB hard drive is expected to be available to the general public later this year. Seagate has already partnered with several leading companies, such as Google, Amazon, and Microsoft, to test and deploy the new technology in their data centers.
According to Seagate, the Exos 30 TB hard drive is a breakthrough in the storage industry, as it marks an inflection point in the evolution of hard disk drives. The company says that the Mozaic 3+ technologies will enable further scaling of hard drive capacity and performance in the future, reaching up to 100 TB by 2028.
The Exos 30 TB hard drive is based on the magnetic storage device technology, which uses microscopic light and dark spots to store data on a spinning disk. The HAMR technology uses a laser to heat up the disk surface, allowing for smaller and more densely packed spots.
The plasmonic writer uses a nano-antenna to focus the laser beam, while the spintronic reader uses a magnetic tunnel junction to read the data. The RISC-V controller is a low-power and customizable processor that manages the data flow and error correction.
The Mozaic 3+ technologies also include some innovative features that enhance the performance and reliability of the hard drive. For example, the media alloy uses a pioneering iron-platinum superlattice structure, which significantly increases the magnetic coercivity of disk media. This allows for precise data writing and unprecedented bit stability.
The nanophotonic laser is integrated into the plasmonic writer sub-system, which ensures greater efficiency and yield. The spintronic reader incorporates quantum technology, which makes it one of the world’s smallest and most sensitive magnetic field sensors. The 12nm integrated controller delivers up to 3 times the performance compared to prior solutions.
As Seagate marks this breakthrough in the storage industry, it underscores the growing importance of areal density in accommodating the increasing volumes of data generated, particularly in the era of artificial intelligence and data-intensive applications.
