Ubiquiti UNAS-Pro-4 UniFi 4-Bay 1U Rackmount NAS with 10G SFP+

The Ubiquiti UNAS-Pro-4 is a compact 1U rackmount UniFi NAS designed for centralized file storage, team collaboration, backup workflows, and high-speed network storage deployments. Built with four 2.5/3.5-inch drive bays, two M.2 NVMe SSD cache slots, and high-availability 10G SFP+ networking, the UNAS-Pro-4 delivers scalable storage performance in a professional rackmount form factor.

Designed for the UniFi ecosystem, the UNAS-Pro-4 runs UniFi Drive and supports file sharing, snapshots, share links, Time Machine backup, remote UNAS backup, CIFS/SMB server backup, and cloud backup services including Google Drive, OneDrive, Dropbox, Amazon S3, Backblaze B2, and Wasabi. This makes it a strong fit for businesses, IT teams, MSPs, offices, creative teams, and UniFi-managed environments that need reliable centralized storage.

The UNAS-Pro-4 includes 8GB of system memory, a quad-core ARM Cortex-A57 processor, an internal 150W power supply, and support for UniFi RPS DC backup input for power redundancy. With dual 10G SFP+ networking and rackmount deployment, it is built for users who need faster access, lower latency, and cleaner storage infrastructure than the usual “external drive plugged into someone’s dusty desktop” disaster.
