Extreme Density, Zero Compromise
Maximise capacity per rack with high-density JBOD infrastructure for software-defined environments. For organisations riding exponential data growth, Exos SCALE systems offer high-density JBODs built for hyperscale and hybrid. SAS-4 throughput, SDS-friendly design and operational simplicity reduce cost and risk, while Mozaic-ready enclosures safeguard your capacity roadmap for tomorrow's drives.
Store more data per rack, reduce long-term TCO and keep your software strategy flexible as your data footprint grows.
Pack more usable capacity into every rack while reducing overhead with Seagate's industry-leading areal density.
Speed ingest and retrieval for modern, data-intensive workloads with 24G SAS throughput.
Integrate seamlessly with software-defined, object and file stacks — without lock-in.
Adopt today's highest-capacity drives and tomorrow's breakthroughs without re-architecting.
Deploy, service and scale with repeatable designs that reduce operational effort.
Lower your data centre power, cooling and footprint costs across the system lifecycle.
Exos SCALE brings Seagate's leadership in mass-capacity storage to high-density expansion, helping organisations grow with greater efficiency, control and confidence. The platform delivers a trusted path to lower cost, higher density and smoother scale across data-intensive environments.
