Seagate Exos M 30TB 512MB 7200 rpm SATA HDD

30TB enterprise capacity | Breakthrough 3TB-per-platter density | Up to 275 MB/s sustained transfer | 2,500,000-hour MTBF | 5-year warranty

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.
