The Ubiquiti UniFi UNAS-4 (UNAS-4-W) is a compact four-bay network-attached storage appliance with dual M.2 NVMe cache, 2.5GbE networking and PoE++ power, managed through the UniFi ecosystem. Listed under part number UNAS-4-W, it brings fast, centrally managed storage to a UniFi network in a clean white desktop design. Typically in stock with fast delivery across Cyprus.
Before you buy
Drives are sold separately — install your own 2.5″/3.5″ SATA HDDs or SSDs, plus optional M.2 NVMe cache. The UNAS-4 is powered by PoE++ and comes with a 90W PoE++ adapter, or you can power it from a PoE++ switch port. It is managed entirely through the UniFi ecosystem, and the four-bay design supports a single RAID group.

✓Small offices and homes needing 2.5GbE file sharing
✓Backups, file servers and shared media on a tidy desktop unit
✓Setups that prefer single-cable PoE++ power

Technical Specifications
Frequently Asked Questions
Singular Expert Insight
The UNAS-4 is the compact, PoE-powered way to add storage to a UniFi network — ideal if you already run UniFi gear and want a NAS that manages from the same app. The 2.5GbE port and dual NVMe cache make it quick for a four-bay unit. If you need more bays, rackmount or higher throughput, look at the larger UNAS Pro models; otherwise browse other NAS and RAID appliances to compare.
Buyer's Guide
Buy it if
You run a UniFi network and want a compact, app-managed 4-bay NAS with 2.5GbE, NVMe cache and tidy PoE++ power.
Skip it if
You need more than four bays, rackmount form, 10GbE, or a NAS that runs outside the UniFi ecosystem.
Also consider
A UniFi UNAS Pro for more bays and rackmount, plus NAS-rated drives and M.2 NVMe cache to complete the build.
