Seagate Exos M 28TB Enterprise 3.5" Hard Drive, SATA 6Gb/s, 7200RPM, CMR Recording Technology | ST28000NM003K

The Seagate Exos M 28TB (ST28000NM003K) represents a significant leap in areal density and Total Cost of Ownership (TCO). Built specifically for the AI era, it allows data centers to scale capacity without increasing their physical footprint or power infrastructure. By integrating Mozaic 3+ technology, Seagate has created a drive that offers massive storage capabilities while maintaining the same 3.5-inch dimensions and interfaces as previous generations.
 

Innovative Engineering: Mozaic 3+ and HAMR
At the heart of the ST28000NM003K is Seagate’s HAMR (Heat-Assisted Magnetic Recording) technology. This allows for smaller data bits that remain stable at high densities, enabling the drive's incredible 28TB capacity. Unlike SMR drives, this model utilizes CMR (Conventional Magnetic Recording) logic for the host, ensuring consistent random write performance and simplified integration into existing enterprise file systems like Hadoop and Ceph.

Elite Reliability: 2.5 Million-Hour MTBF
The Exos M series is built for 24/7/365 operational excellence. It features an MTBF of 2.5 million hours and a workload rating of 550TB per year, making it one of the most durable drives on the market. The helium-sealed design reduces aerodynamic drag on the platters, which not only lowers power consumption to just 6.9W at idle but also enhances mechanical longevity by reducing internal heat and friction.
 

Seagate Secure and Power Management
Security is non-negotiable in enterprise environments. The ST28000NM003K includes Seagate Instant Secure Erase (ISE) for easy and safe drive retirement. Furthermore, it utilizes PowerChoice™ and PowerBalance™ technologies, allowing administrators to customize power consumption and performance profiles to meet specific data center efficiency goals without sacrificing responsiveness.
 

Why the Exos M 28TB Stands Out
3TB Per Platter: Unprecedented density for maximum storage per rack.

HAMR Technology: Cutting-edge recording that enables higher capacities than traditional PMR.

Superior Power Efficiency: Up to 3x the power efficiency per terabyte compared to lower-capacity enterprise drives.

5-Year Limited Warranty: Comprehensive support for mission-critical deployments.
