My NVR reported a storage failure during the same half hour I had unsupervised houseguests in the building. By that evening it claimed storage was fine and showed no recordings at all.
Nothing malicious happened. It took an evening of forensics to be able to say that, and the answer is the least interesting part of this. What’s worth writing down is how many of the intermediate answers were wrong, and how confidently the tooling handed them over.
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.
