As Convenient As it Gets
Enjoy the security and benefits of an affordable, low-risk NAS setup with the Ubiquiti UNAS 4 — a sleek, rounded desktop unit with four bays for storage expansion. Flip it on its side to access four caddies, each supporting a 3.5" SATA HDD. A 1.47" color display on the front panel keeps you informed of drive speeds and failures, while a 2.5GbE RJ45 port and a USB-C port provide flexible connectivity. The unit also comes with a 90W PoE+++ adapter for added convenience, perfect for the unit's 80W total budget.
Small, but Serious
Networking runs through the 2.5GbE RJ45 port, compatible with 2.5G/1G/100M/10M speeds. Expansion and peripheral support are available via the 5 Gbps USB-C port, backed by the included 90W adapter.
Quad-Core CPU & 4GB Memory
Powered by a Quad-Core ARM® Cortex®-A55 processor at 1.7 GHz and 4 GB of memory, the UNAS 4 manages multiple drives and client connections efficiently. System LEDs indicate operational status, while Bluetooth 4.1 enables wireless interactions. The device operates safely in ambient temperatures from -5 to 40°C (23 to 104°F) and humidity levels of 10 to 90% noncondensing.
UniFi Ecosystem
The UNAS 4 runs on UniFi Drive, version 3.4.5 or later, with mobile app support for iOS (10.32.1+) and Android (10.35.1+). Supported file protocols include NFS and SMB, while the management portal on unifi.ui.com offers personal and shared drives, backup to remote UNAS devices, CIFS/SMB servers, and cloud services such as Google Drive, OneDrive, Dropbox, Amazon S3, Backblaze B2, and Wasabi.
