UniFi’s new UNAS lineup brings scalable, license-free network storage to homes, small offices, and enterprises.
Ubiquiti has introduced a comprehensive update to its storage ecosystem with the unveiling of its new UniFi UNAS lineup, designed to deliver scalable and reliable storage for users ranging from home enthusiasts to enterprises. The refreshed range features the UNAS 2, UNAS 4, UNAS Pro 4, and UNAS Pro 8, catering to varying storage demands. The new line offers a blend of elegant design, solid performance, and flexibility, all unified under the UniFi Drive platform.
UNAS 2: Streamlined Desktop Storage with Essential Features
The UNAS 2 is designed as a simple, compact desktop NAS tailored for users who prioritize ease of deployment and quiet operation. Built with a lightweight polycarbonate enclosure, it supports two 3.5″ hard drives and relies on a single PoE++ connection for both power and network, eliminating the need for a separate power adapter. A USB-C expansion port adds flexibility for attaching external devices, while the 1.47-inch color LCM display provides basic system status at a glance.
With a Quad-Core ARM Cortex-A55 processor clocked at 1.7 GHz and 4 GB of memory, the UNAS 2 is optimized for lightweight tasks such as file sharing, media access, and basic backup functions. Although it lacks SSD or NVMe support, its minimal footprint and 60W power ceiling make it suitable for small offices or home networks seeking a quiet, plug-and-play storage solution. Its NDAA compliance and operating tolerances make it ideal for various regulated environments.

UNAS 4: Versatile Mid-Tier Storage with NVMe Expansion
The UNAS 4 builds on the same desktop footprint as the UNAS 2, but adds performance features designed for users with larger or more demanding workloads. It doubles the drive bay capacity to four and introduces support for two M.2 NVMe SSDs, allowing for cache acceleration or tiered storage. Like its smaller sibling, the device utilizes PoE+++ for power, featuring a higher 90W adapter to meet the increased demand from larger drive configurations and SSDs.
Internally, the processor and memory remain the same (a Quad-Core ARM Cortex-A55 at 1.7 GHz and 4 GB RAM). Still, the expanded storage and power headroom provide flexibility in scenarios such as media production, surveillance storage, or branch office file sharing. The same 2.5 GbE RJ45 port handles network connectivity, and it retains the USB-C expansion port and color display. The UNAS 4 strikes a balance between simplicity and performance, particularly for teams that require more capacity without upgrading to a rackmount system.
