Why is there only one Exos name now?

Simplified. Unified. Unstoppable. Exos is your unified source for enterprise-class storage.

What was once split across X, E and M is now streamlined under a single, powerful name — Exos. Easily choose the right capacity for any workload and know that you’re getting the same dependable performance, capacity and reliability you’re used to.

Built for today — and tomorrow. Exos: the enterprise standard for capacity, performance and peace of mind.

How much capacity do 3TB-per-platter Exos drives reach?

Breakthrough density. Breakthrough possibilities. A new era of Exos designed for data-intensive performance.

Built on Mozaic’s next-gen precision engineering, our latest Exos hard drives give data-intensive environments exactly what they need: more capacity in the same footprint. With 24TB to 32TB options and unmatched areal density, you get consistent performance, better efficiency and the scale to keep data-hungry workloads moving.

3TB+ per platter density maximizes capacity without increasing your data center footprint. Up to 32TB per drive flexes with fast-expanding AI, cloud and enterprise workloads. And Mozaic™ technology delivers higher efficiency, improved reliability and better TCO at scale.
