UGREEN NAS DH4300 Plus 4-bay 120TB with 2.5GbE and USB-C

UGREEN NAS DH4300 Plus 4-bay 120TB with 2.5GbE and USB-C is a compact network-attached storage appliance designed to consolidate local data storage, backup and media serving for home offices and small businesses. The enclosure supports four 3.5" or 2.5" drives, delivering up to 120 TB raw capacity and providing a straightforward way to store large volumes of files on a single device. Built-in 2.5 Gigabit Ethernet improves LAN throughput compared with standard 1GbE connections, and the USB-C port enables direct-attached storage expansion or fast data transfer to external drives.

Advantages

The NAS offers multi-bay flexibility and centralized management for backups, file sharing and media streaming without relying on cloud services. 2.5GbE connectivity reduces network bottlenecks for simultaneous users and large file transfers. The USB‑C interface provides a convenient option for expanding storage or importing/exporting data quickly. The device is suitable for continuous operation with straightforward drive installation and common NAS services supported.

Suitable for

• Centralized file storage and shared folders in a home office or small office
• Automated backups for multiple PCs and mobile devices
• Local media streaming to smart TVs and media players
• Data consolidation and archiving for small businesses
• Temporary direct-attached transfers via USB-C for large datasets

Key specifications

• Drive bays: 4 (supports 3.5" and 2.5" SATA drives)
• Maximum raw capacity: up to 120 TB (depending on installed drives)
• Network interface: 2.5 Gigabit Ethernet port for higher LAN throughput
• External interface: USB‑C port for direct-attached storage and data transfer
• Form factor: desktop 4-bay NAS enclosure for local placement
• Use case focus: centralized backup, file sharing, media streaming

How to use

Install compatible SATA drives into the four drive bays following the manufacturer’s physical installation procedure, then connect the NAS to your local network using the 2.5GbE port and an appropriate switch or router. Power on the device and complete initial setup through the device’s web or application-based management interface to configure storage volumes, shared folders, user accounts and backup tasks. Connect an external drive to the USB‑C port when you need to import large amounts of data or add temporary storage without opening the enclosure.

Usage recommendations

For reliable operation, use drives designed for NAS use that match in capacity and rotational speed where possible, and place the NAS on a stable, ventilated surface. Ensure your network infrastructure (switches and cables) supports 2.5GbE to take full advantage of the improved network speed. Regularly configure scheduled backups and firmware updates via the management interface to maintain data integrity and security.
