Seagate Exos M 30TB 512MB 7200 rpm SATA HDD

What this part is

<p><strong>30TB enterprise capacity | Breakthrough 3TB-per-platter density | Up to 275 MB/s sustained transfer | 2,500,000-hour MTBF | 5-year warranty</strong></p> <p>The Seagate Exos M 30TB is an enterprise-class 3.5-inch hard drive built for hyperscale cloud data centres, high-density RAID arrays, AI workloads, and big-data applications that demand maximum capacity without expanding their physical footprint. Powered by Seagate's Mozaic 3+ technology and the world's first 3TB-per-platter design, it packs 30TB of CMR storage into a standard 3.5-inch form factor while delivering a maximum sustained transfer rate of 275 MB/s and an average latency of 4.16 ms. A 512 MB multisegmented cache, 7,200 RPM spindle speed, and SATA 6 Gb/s interface keep throughput consistent under the continuous 24×7 workloads these environments demand. Helium-sealed construction, PowerChoice idle power technology, and PowerBalance power/performance technology combine to offer 3× the power efficiency per terabyte compared to typical drives — directly reducing operational and cooling costs. With a 2,500,000-hour MTBF, a 0.35% annualised failure rate, and built-in Seagate Secure data protection with RSA 3072 firmware verification, the Exos M is engineered for always-on reliability in mission-critical infrastructure. It maintains the same form factor, interface, and cooling profile as previous Exos generations, making integration into existing storage arrays straightforward. Backed by a 5-year limited warranty.</p> <h3>Features</h3> <ul> <li>30TB CMR capacity in a standard 3.5-inch form factor, enabled by breakthrough 3TB-per-platter Mozaic 3+ technology</li> <li>Maximum sustained transfer rate of 275 MB/s (OD) for high-throughput enterprise workloads</li> <li>512 MB multisegmented cache and 7,200 RPM spindle speed maintain consistent performance under continuous 24×7 operation</li> <li>Helium-sealed drive design with PowerChoice and PowerBalance technologies deliver 3× the power efficiency per terabyte compared to typical drives</li> <li>2,500,000-hour MTBF and 0.35% AFR for enterprise-grade reliability in always-on environments</li> <li>Seagate Secure with RSA 3072 firmware verification provides built-in data protection against threats</li> <li>Hot-plug support and compatibility with existing Exos-generation infrastructure simplifies deployment and upgrades</li> <li>Super Parity and nonrecoverable read error rate of 1 sector per 10E15 bits ensure data integrity at scale</li> </ul> <h3>Specifications</h3> <ul> <li>Release Year: 2025</li> <li>Capacity: 30TB</li> <li>Form Factor: 3.5-"</li> <li>Interface: SATA 6Gb/s</li> <li>Rotational Speed: 7200 RPM</li> <li>Cache: 512MB</li> <li>Workload Class: Enterprise</li> <li>Warranty: 60 months</li> <li>Product Dimensions: 14.7 x 10.1 x 2.6 cm</li> <li>Product Weight: 695g</li> </ul> <h3>What's in the Box</h3> <ul> <li>Seagate Exos M 30TB 512MB 7200 rpm SATA HDD x1</li> </ul>
