Overview
The Ubiquiti UNAS-2-W is a UniFi 2-bay Network Attached Storage system designed for centralized file storage and management. It provides two 3.5-inch HDD bays, a 2.5GbE Ethernet interface, 5 Gbps USB-C expansion, and management through UniFi Drive.
Storage and Data Management
The UNAS-2-W supports two 3.5-inch hard drives and provides RAID 1 as its specified RAID configuration. UniFi Drive supports personal and shared drives, file encryption, snapshots, share links, and user groups. Supported file protocols include SMB and NFS.
The system also supports backup to another UNAS device, CIFS/SMB servers, and supported cloud services including Google Drive, OneDrive, Dropbox, Amazon S3, Backblaze B2, and Wasabi.
Network and Expansion
A single 2.5 GbE RJ45 interface provides 2.5G, 1G, 100M, and 10M Ethernet connectivity. The network interface is also used for Ethernet management and PoE++ power delivery.
A 5 Gbps USB-C expansion port provides connectivity for supported USB storage and other compatible USB devices. The system also includes Bluetooth 4.1 for supported wireless functionality.
Hardware and Power
The UNAS-2-W uses a quad-core ARM Cortex-A55 processor operating at 1.7 GHz and includes 4 GB of memory. The unit has a maximum drive power budget of 52W and maximum system power consumption of 60W.
Power is supplied through PoE++, with a 60W PoE++ adapter included by Ubiquiti. The desktop enclosure uses polycarbonate construction and includes a 1.47-inch color LCM display for system information.
Key Features
- Two 3.5-inch HDD bays with RAID 1 support
- 2.5 GbE RJ45 networking with support for 2.5G/1G/100M/10M speeds
- 5 Gbps USB-C expansion port
- UniFi Drive support for SMB, NFS, snapshots, encryption, and backup features
- 60W PoE++ power system with included PoE++ adapter
Applications
The UNAS-2-W can be deployed as centralized network storage for files, shared folders, backups, and other supported UniFi Drive storage workflows. Its two-drive configuration provides a compact storage platform for environments that require network-accessible storage with RAID 1 support.
DC Supplies Product Note
The UNAS-2-W is a diskless 2-bay storage platform in terms of its storage capacity specification: Ubiquiti specifies two 3.5-inch HDD bays rather than a preinstalled storage capacity. Storage selection should therefore account for the supported 3.5-inch drive configuration and the 52W maximum drive power budget. RAID 1 is the specified RAID type for this model.
