Ubiquiti UNAS Pro
The UNAS Pro was Ubiquiti’s first attempt at a NAS appliance, and it shows. If your requirements are SMB shares, NFS exports, RAID, and snapshots, it handles those reliably—the 10GbE connectivity is a genuine strength, and once a share is configured it works like any other file server. But the software shipped before it was fully baked and arguably still isn’t: no iSCSI, no built-in rsync or scp in the UI, sparse feature additions over time, and an admin interface tied to UniFi Identity that adds friction to what should be straightforward. If you’re coming from Synology or TrueNAS expecting a rich ecosystem of packages and services, recalibrate your expectations. The UNAS Pro is best understood as a UniFi-native file server that does the basics well, and the newer UNAS Pro 8 is a better buy if you don’t already own the original.
