The Ubiquiti UniFi Enterprise Storage Expansion is a 3U rack-mount expansion unit designed to add seamless high-capacity HDD and SSD storage to UniFi Enterprise NAS and Enterprise NVR Core deployments. Built for scalable storage environments, it provides sixteen 2.5 inch or 3.5 inch drive bays, allowing organisations to expand capacity as data, backup, or surveillance retention requirements grow.

With support for up to sixteen additional HDDs or SSDs, the UniFi Enterprise Storage Expansion provides a straightforward way to increase storage density without replacing the core system. It is ideal for large-scale video recording, shared storage, media archives, backup repositories, and other capacity-heavy workloads that require reliable expansion within a standard rack environment.

High-speed SFF-8644 expansion connectivity enables direct integration with compatible ENAS and Enterprise NVR Core systems, supporting scalable storage growth while maintaining a clean rack-mounted architecture. This makes it a practical option for deployments where storage requirements are expected to increase over time.

Designed for continuous operation, the unit includes dual hot-swappable power supplies and hot-swappable fan modules, helping maintain uptime and simplify maintenance in critical environments. Combining 16-bay capacity, redundant hardware, and a 3U rack-mount design, the UniFi Enterprise Storage Expansion provides a robust path for expanding UniFi enterprise storage infrastructure.
