Ubiquiti is expanding its UNAS family with new desktop and rackmount models designed for home labs, creators, and small businesses that want fast, flexible, and space‑efficient storage. The lineup now includes the compact UNAS 2, the higher‑capacity UNAS 4, and three rackmount options under the UNAS Pro name: UNAS Pro, UNAS Pro 4, and UNAS Pro 8.

– Price and availability: approximately $199 and available now
UNAS 4: more bays and SSD flexibility
– Four 3.5-inch bays plus two M.2 SSD slots, all accessible from the rear

Which UNAS should you pick?
– Choose UNAS 2 if you want an affordable, space‑saving NAS for backups, media libraries, and home office sharing with 2.5GbE and the convenience of PoE++.
– Step up to UNAS 4 if you need more storage flexibility, including M.2 SSDs for cache or fast tiers, and don’t mind the higher power budget.
– Go for a UNAS Pro model if you require rackmount density, shallow‑depth installations for tight network cabinets, and features aimed at more advanced deployments.
Key takeaways
– Ubiquiti now offers a clear path from entry‑level desktop NAS to compact, cabinet‑friendly rack solutions.
– 2.5GbE and PoE power options make deployment simpler across the lineup.
– Pricing spans roughly $199 to $799, depending on capacity and form factor, with broader availability ramping through late 2025.
If you’re building a home lab, modernizing a small office, or consolidating media and project storage, the expanded UNAS line delivers faster networking, neat power options, and thoughtful physical designs tailored to real‑world spaces.
