Seagate, the American data storage company, has launched a new Exos 30 TB hard drive utilizing the company’s Mozaic 3+ technology. 

The Exos 30 TB is an enterprise-grade device with Moziac 3+ as its main highlight. The latter allows it to pack 30 terabytes of information onto spinning magnetic platters into the hard disk. 

The key to this high density lies in several technological advancements. First, Mozaic 3+ replaces traditional iron-alloy magnetic media with smaller, denser platinum-alloy nanoparticles. This allows for more data to be stored in the same physical space, akin to writing more words on a page without increasing its size.

However, writing and reading data at this microscopic scale presents additional challenges. To address this, Mozaic 3+ employs a laser-assisted writing process, where a focused beam heats specific areas to facilitate magnetic bit formation. This method requires less energy than traditional writing methods.

Reading these densely packed bits demands exceptional precision. Mozaic 3+ utilizes a highly sensitive magnetic reader that can detect subtle changes in magnetism representing each bit. Furthermore, a powerful RISC-V controller ensures accurate head positioning and high-speed data processing.

Beyond its impressive capacity, the Exos 30 TB boasts lower power consumption, making it attractive for data centers focused on energy efficiency. While currently targeted at businesses, consumer versions are expected in the future, potentially offering unprecedented storage possibilities for home users.

The Exos 30 TB is also not merely a matter of bigger numbers. It represents a significant step towards even larger drives, with Seagate aiming for 50 TB+ capacities in the near future.
