In an era of explosive digital content growth, the demand for home data storage is increasing exponentially. From 4K videos and RAW-format photos to smart home surveillance footage and personal creative content, traditional storage devices are no longer sufficient to meet the diverse needs of modern households. UGREEN’s newly launched DH4300 Plus four-bay private cloud NAS offers a comprehensive set of features, delivering a professional-grade storage solution tailored for home users.

Design and Hardware: Compact Form, Powerful Performance

The DH4300 Plus features an innovative vertical design, with a sleek titanium-gray metal body and rounded corners that save space while maintaining a modern aesthetic. Its compact dimensions (exact size TBD) allow it to blend seamlessly into any home environment. The magnetic top cover is not only easy to remove but also integrates NFC functionality—users can simply tap their phone to quickly download the companion app.

On the hardware side, the DH4300 Plus is equipped with an octa-core ARM A55-A76 processor, 8GB LPDDR4X RAM, and 32GB of eMMC flash storage, ensuring smooth and efficient system performance. The inclusion of a 2.5GbE high-speed Ethernet port allows for data transfer rates up to 2.5 times faster than traditional Gigabit networks. The four drive bays support up to 30TB per drive, offering a total storage capacity of up to 120TB—more than enough for even the most storage-hungry households.

The device offers versatile connectivity: a front-facing USB 3.2 Gen1 Type-C port, rear HDMI output, two USB-A 3.2 Gen1 ports, and a 2.5GbE LAN port enable easy expansion with peripherals and display devices. Its thermal design uses a top-to-bottom airflow system, supported by an intelligent fan control mechanism, to ensure long-term stability and efficient heat dissipation.

Storage Performance: Fast and Reliable

In real-world performance testing, the DH4300 Plus delivered impressive results. When connected directly to a test platform via a 2.5GbE network, CrystalDiskMark recorded sequential read and write speeds of 296.5MB/s and 292.17MB/s, respectively. In practical file transfer testing using a 20GB 4K Blu-ray movie, average write speeds reached 171.6MB/s, while read speeds climbed to 200.2MB/s.

The device utilizes a smart caching strategy. During write operations, it first leverages the eMMC cache to achieve speeds exceeding 200MB/s. Once the cache is filled, performance stabilizes around 150–160MB/s. Read performance is even more stable, generally holding between 180–190MB/s. These figures make it more than capable of smoothly streaming 4K HDR content, fulfilling the role of a home multimedia hub.

UGOS Pro System: Professional Features, User-Friendly Design

The DH4300 Plus runs UGOS Pro, one of its standout advantages. This NAS operating system, designed specifically with home users in mind, features an intuitive graphical interface that significantly lowers the learning curve. It supports access across multiple platforms—including Windows, macOS, iOS, and Android—and can even be managed remotely via a web browser.

File management is thoughtfully designed, offering personal folders, shared folders, and user-specific directories with flexible permission settings. Storage management includes support for seven different RAID configurations, from simple Basic mode to secure RAID 5, allowing users to choose based on their data protection needs. Notably, the system supports macOS Time Machine backups, providing Apple users with a robust data protection solution.

Remote access is handled through the UGREENlink service. Users can establish secure connections by simply entering a unique ID. The system includes access nodes across the Americas, Europe, and Asia to ensure stable global connectivity. Advanced users will appreciate support for DDNS and multiple file service protocols (SMB, FTP, NFS, etc.), making it adaptable to a wide range of usage scenarios.

Home Entertainment Hub: More Than Just Storage

The DH4300 Plus is not just a storage solution—it’s a full-fledged home entertainment center. By connecting directly to a TV via the HDMI port and using the built-in media center app, it can serve as a professional-grade home theater system. In testing, it smoothly played 4K Blu-ray discs, with support for HDR and Dolby Vision, and offered seamless fast-forwarding with no buffering.

The media center integrates with the TMDB database to automatically generate visually rich poster walls and intelligently categorize content into movies, TV shows, and more. The mobile app can be used as a remote control to play content, switch audio tracks, and toggle subtitles—offering an experience comparable to high-end media players. With audio passthrough functionality, high-fidelity digital audio can be sent directly to a home sound system for an immersive viewing experience.

Photography enthusiasts will appreciate the AI-powered photo album feature. Using NPU-accelerated image recognition, it can automatically sort photos, identify people, create baby albums, and even support semantic search. The photo backup feature enables automatic uploads from mobile phones, solving storage space issues once and for all. During testing, the system accurately recognized EXIF data such as camera model, shooting date, and geolocation, helping users efficiently organize large photo collections.

Conclusion

The UGREEN DH4300 Plus is a professional-grade four-bay NAS solution with robust hardware, a user-friendly OS, rich multimedia capabilities, and reliable performance—all tailored for home users. Whether used as a data storage hub, home theater server, or photo backup center, it handles every role with ease. For users seeking a cost-effective, easy-to-use, and feature-complete home NAS system, the DH4300 Plus is a compelling choice well worth considering.
