UniFi UNAS Pro: what it is & who it's for

Seven bays for $499 works out to $71 a bay, against $100 on the UNAS Pro 8 and $125 on the UNAS Pro 4. What it gives up to the Pro 8 is everything around the bays: no NVMe cache, one SFP+ port instead of two, 1.7 GHz instead of 2.0 and half the memory. Bulk capacity on a budget: backups, archives and media where bay count matters more than cache, clock speed or a second uplink.

Pros
  • Seven 2.5/3.5" bays at $499 — three more than the same-priced UNAS Pro 4
  • Multiple RAID groups and hot-spare support
  • 325 mm deep, 155 mm shallower than the UNAS Pro 8
  • 1.3" touchscreen on the front panel, and a USP-RPS DC input
Cons
  • No M.2 NVMe bays and no SSD cache row on the spec sheet
  • One 10G SFP+ port and a 1 GbE RJ45 — there is no second 10-gigabit path
  • Cortex-A57 at 1.7 GHz and 8 GB, against 2.0 GHz on the UNAS Pro 4 and Pro 8, and 16 GB on the Pro 8
  • Redundant power means buying a USP-RPS
