Yes. The Exos M is purpose-built for hyperscale cloud service providers and massive scale-out data centres, offering 30TB of capacity, enterprise-class reliability, and superior power efficiency for AI-driven and big-data workloads.
What interface does this drive use?
The Exos M 30TB uses a SATA III (6 Gb/s) interface, suitable for standard server and RAID array SATA controllers.
How reliable is the drive and what warranty is provided?
The drive is rated at 2.5 million hours MTBF with a 0.35% annualised failure rate at full 24x7 operation. Seagate provides a 5-year limited warranty.
What makes the Exos M different from previous Exos generations?
The Exos M is built on Seagate's Mozaic 3+ platform, the first hard drive technology to achieve 3TB per platter. It blends 90% of proven, trusted components from earlier Exos generations with this next-generation recording technology, delivering more capacity in the same footprint and up to 3x the power efficiency per terabyte, while keeping the same form factor, interface, and cooling requirements for easy integration into existing infrastructure.
Is this drive suitable for AI and big data applications?
Yes. The Exos M is designed for AI, big data analytics, and high-capacity density RAID storage, as well as distributed file systems such as Hadoop and Ceph, and enterprise backup and restore (D2D, virtual tape) environments.
