High-capacity UniFi storage with resilient power
The Ubiquiti UNAS-Pro-8 UniFi NAS is designed for larger file-storage and sharing environments managed through UniFi Drive. It supports SSD caching, NFS and SMB, file encryption, snapshots, share links, Time Machine backup and multiple local, remote and cloud backup targets.
Eight primary drive bays
Eight qualified 2.5-inch or 3.5-inch drives provide the main storage tier.
Multiple 10G interfaces
Two 10G-only SFP+ ports and one multi-rate 10GbE RJ-45 port support high-speed network design.
Dual NVMe cache bays
Two M.2 NVMe bays support SSD caching with a listed 4TiB maximum NVMe capacity.
Multiple RAID groups
The current platform supports multiple RAID groups and hot-spare configuration.
Hot-swappable power modules
Two 550W AC/DC power modules provide the specified redundant power design.
Rack-ready UniFi management
UniFi Drive centralises file access, encryption, snapshots, shares and backup workflows.
Who is the Ubiquiti UNAS-Pro-8 UniFi NAS best for?
A strong choice for
- Larger UniFi file-storage deployments
- Multiple RAID groups and hot-spare planning
- 10GbE-connected workgroups
- Rack environments needing redundant power modules
- Local, remote and cloud backup
Consider another model if you need
- You need more than eight primary drive bays
- Your rack does not meet the stated rail-depth requirements
- You do not have 10Gbps network infrastructure
- Your drives are not on Ubiquiti's qualified list
