  • Unmatched areal density
  • Industry-leading capacities of up to 36 TB


Seagate’s Bold Move in Data Storage

Seagate Technology Holdings plc is stirring up the world of data storage with their latest announcement: they’ve started shipping samples of their Exos M hard drives to select customers. These drives boast industry-leading capacities of up to a staggering 36 terabytes (TB). What’s the secret sauce behind this leap? It’s all thanks to their Mozaic 3+ technology, which is based on a method known as heat-assisted magnetic recording (HAMR). With Exos M, Seagate is setting a new standard for large-scale data center deployments.

Key Highlights of the Exos M Launch

So, what does this mean for the industry? For starters, Seagate is ramping up to volume shipments of Exos M drives with capacities of up to 32 TB for a leading cloud service provider. But wait, they’re not stopping there. They’re also sampling drives that push the limits to 36 TB. Imagine the scale of data storage this could bring to cloud services!

Revolutionary Technology: Mozaic 3+ and HAMR

Let’s dive a bit deeper into what makes the Exos M so special. The Mozaic 3+ platform, which is the first of its kind to implement HAMR, offers significant advantages for data center operators. We’re talking about a 300% increase in storage capacity while occupying the same data center footprint! Plus, it slashes costs by 25% per terabyte and reduces power consumption by 60%. That’s not just smart—it’s essential in today’s data-driven world.

Unmatched Areal Density

The Exos M drives are designed with a highly efficient 10-platter system, allowing them to achieve capacities of up to 36 TB. Seagate stands alone in the data storage realm, boasting areal densities of 3.6 TB per platter. And they’re not done yet; there’s a clear pathway to eventually reach 10 TB per platter. That’s a game changer for anyone looking to maximize their storage capabilities.

Dell Technologies Joins the Revolution

Dell Technologies is among the first to embrace this innovation, integrating the Exos M 32 TB drives into their high-density storage systems. Travis Vigil, SVP of ISG Product Management at Dell, emphasizes the need for scalable and flexible storage solutions as businesses ramp up their AI capabilities. “As customers build out their AI factories, they need cost-efficient, scalable, and flexible storage engineered to reliably handle the most demanding AI workloads,” he explains. Together, Dell and Seagate are setting the stage for the future of AI storage.

Seagate’s Vision for the Future

Dave Mosley, Seagate’s CEO, paints a vivid picture of the seismic shifts happening in data storage and management. “Unprecedented levels of data creation—driven by cloud expansion and early AI adoption—demand long-term data retention and access,” he states. The more data organizations can retain, the better they can ensure that their applications are functioning as intended. Seagate is not just keeping pace; they’re leading the charge, having demonstrated capacities of over 6 TB per disk in their test labs.

The Industry’s Perspective

Kuba Stolarski, Research Vice President at IDC, highlights the growing importance of hard drives in the age of AI. “As businesses and people everywhere continue to use AI applications, more widespread adoption of AI is creating unprecedented amounts of data,” he points out. With 89% of data in leading cloud service providers’ data centers stored on hard drives, Seagate’s advancements in areal density position them perfectly to meet this rising demand.

Conclusion: A New Era in Data Storage

In a world where data is king, Seagate’s Exos M hard drives are not just a step forward; they’re a leap into the future. With their innovative technology and unmatched capacity, they’re ready to tackle the challenges of tomorrow’s data landscape. Are you prepared to embrace this new era of data storage?
