Seagate Exos M 30TB HAMR SATA 3.5" Enterprise HDD

The Seagate Exos M 30TB (ST30000NM005L) is a 3.5-inch SATA enterprise hard drive built on Seagate's Mozaic 3+ platform, which introduces Heat-Assisted Magnetic Recording (HAMR) technology to achieve 30TB of native capacity in a standard large-form-factor chassis. HAMR uses a laser-assisted write process to temporarily heat the recording medium to extreme temperatures, enabling the use of high-stability FePt (iron-platinum) alloy media that supports far higher areal density than conventional PMR or SMR technologies. This architecture allows Seagate to extend capacity scaling well beyond the physical limits of traditional magnetic recording, making the Exos M series a foundational component of next-generation hyperscale and AI infrastructure storage tiers.

Designed for continuous 24×7 operation in demanding data center environments, the Exos M 30TB targets workloads that require maximum storage density per rack unit while maintaining enterprise-grade reliability. The drive is rated for a 550TB per year workload, reflecting its suitability for bulk sequential write applications such as object storage, cold and warm AI training datasets, large-scale backup repositories, and media content archives. With a 2.5 million hour mean time between failures (MTBF) rating and support for Seagate's PowerChoice power management technology, the drive is engineered to balance high-density capacity with manageable power profiles across large-scale deployments.

The ST30000NM005L interfaces via SATA 6Gb/s, making it compatible with the broad ecosystem of existing SATA HBA and controller infrastructure without requiring SAS-specific hardware. A 512MB cache buffer supports sustained sequential throughput, and the drive ships with Seagate's Secure erase and ISE (Instant Secure Erase) capabilities to meet data sanitization requirements for enterprise and regulated environments. As part of the broader Exos M family, the ST30000NM005L represents Seagate's production HAMR offering positioned for hyperscale operators, cloud storage builders, and AI infrastructure teams requiring the highest capacity-per-drive available on the SATA interface.

Ideal for

• Hyperscale object storage clusters requiring maximum raw capacity per drive bay to minimize rack space and power per petabyte
• AI and machine learning training data lakes storing large unstructured datasets including images, video, and sensor data at scale
• Large-scale cold and warm backup repositories for enterprise data protection and long-term retention workflows
• Media and entertainment archives holding high-resolution video assets, rendering outputs, and production content libraries
• High-density NAS and scale-out file system deployments in cloud and colocation environments prioritizing capacity density
• Data center tiering solutions serving as the capacity tier beneath NVMe and SAS performance layers in multi-tier storage architectures
