UGREEN NASync DXP4800 Plus review: strong hardware, maturing software

Hardware that punches above its weight class

The DXP4800 Plus ships with a 12th-generation Intel Pentium Gold 8505 processor, a five-core six-thread chip that sits between the budget N100 found in entry-level NAS boxes and the full Core i5 chips reserved for high-end models. Independent reviews confirm that this processor handles Docker workloads, multiple simultaneous users, and hardware-accelerated Plex transcoding without breaking a sweat. The inclusion of 8GB of DDR5 RAM as standard, expandable to 64GB, gives the platform significant headroom for virtual machines and container-heavy workflows.

The standout feature at this price point is the built-in 10GbE port alongside a 2.5GbE port. Competitors like the Synology DS923+ require an add-in card to achieve 10GbE, and that card alone can cost several hundred dollars. Reviewers measured real-world transfer speeds approaching 1,250 megabytes per second over the 10GbE link when paired with compatible network infrastructure. The unit also includes two M.2 NVMe slots for SSD caching or dedicated fast storage pools, and a dedicated 128GB SSD holds the operating system rather than relying on slower eMMC or USB DOM solutions common in this segment.

Build quality is solid. The aluminum chassis feels premium, drive trays are tool-free for 3.5-inch drives, and UGREEN includes thoughtful touches like a magnetic dust filter over the rear fan and high-quality CAT7 network cables in the box. The unit supports RAID 0, 1, 5, 6, 10, and JBOD configurations with Btrfs or Ext4 file systems.

UGOS Pro: clean interface, thin ecosystem

UGOS Pro, the Debian 12-based operating system powering the DXP4800 Plus, draws clear inspiration from Synology DSM. The web interface is clean, responsive, and approachable for first-time NAS users. Initial setup walks through drive configuration, RAID selection, and user account creation in a logical sequence. Multiple reviewers praised the ease of getting the system online, though one noted that Windows SMB sharing is disabled by default and requires manual activation.

The challenge lies in what comes after setup. UGOS Pro launched with a limited native app library. Users seeking one-click installs for Plex, surveillance camera management, or advanced backup solutions will find gaps. UGREEN supports Docker and includes a proprietary virtual machine app, so technically proficient users can deploy containerized versions of missing apps, but this requires comfort with Docker Compose files and command-line troubleshooting. For buyers expecting the breadth of Synology Package Center or QNAP App Center, UGOS Pro in mid-2026 still feels like a work in progress.

On the positive side, UGREEN has pushed regular firmware updates since launch. Docker support is mature, the AI-powered photo management app offers face and object recognition with semantic search, and core file-sharing protocols including SMB, NFS, AFP, FTP, and WebDAV work reliably. The platform includes snapshots via Btrfs, two-factor authentication, and configurable firewall rules. Reviewers noted that by 2026 the operating system had matured considerably from its early beta state, though it remains behind DSM and QTS in depth.

Value proposition versus Synology and QNAP

At 620 to 700 dollars diskless, the DXP4800 Plus directly challenges the Synology DS923+ at around 600 dollars and the QNAP TS-464 at roughly 550 dollars. On pure hardware, UGREEN wins convincingly. The DS923+ uses a dual-core AMD Ryzen R1600 without hardware transcoding and ships with 4GB of non-expandable ECC RAM and 1GbE networking; adding 10GbE requires a card that pushes total cost well above the DXP4800 Plus. The QNAP TS-464 offers a quad-core Intel Celeron N5095, 8GB of DDR4, and dual 2.5GbE, but lacks native 10GbE and tops out at 16GB of RAM. UGREEN's 5-core CPU, DDR5, 10GbE, and 64GB RAM ceiling represent a generation leap in hardware at a lower or comparable entry price.

The software trade-off is real. Synology DSM offers Active Backup for Business, mature surveillance station licensing, a vast app library, and two decades of ecosystem refinement. QNAP QTS supports ZFS file systems for advanced data integrity and includes robust multimedia tools. Both platforms have extensive community documentation and third-party support. UGOS Pro, by contrast, requires users to bring Docker skills or patience as the app ecosystem matures. One comparison analysis noted that Synology's three-year warranty and established track record may justify higher costs for risk-averse businesses, while UGREEN's two-year warranty and newer platform status demand more active management.

For buyers prioritizing raw performance, 10GbE networking, and freedom from vendor drive lock-in, the DXP4800 Plus offers exceptional value. For those prioritizing plug-and-play simplicity, enterprise backup features, or a mature software ecosystem, Synology and QNAP remain safer bets despite weaker hardware at the same price.

Real-world performance and daily use

Multiple independent reviewers tested the DXP4800 Plus with RAID 5 arrays using WD Red Plus and Seagate IronWolf drives. File transfer performance over 10GbE consistently approached the theoretical maximum, with one tester reporting 1GB copied in under one second. The front-panel SD card reader and USB ports proved convenient for direct camera offloads without a PC intermediary. Noise levels in default fan mode were reported as very quiet, with one reviewer unable to hear the fan at all, though another noted the fan could become loud under sustained load.

Docker containers for Home Assistant, Pi-hole, Nextcloud, Vaultwarden, and Portainer were confirmed working by multiple sources. One reviewer successfully ran a Windows 11 virtual machine on the platform, leveraging the 12th-gen Intel CPU and DDR5 memory, though performance was noted as suitable for office tasks rather than gaming. The HDMI port supports 4K 60Hz output, enabling direct media playback, though the lack of a native Plex app means users must deploy it via Docker. Several testers warned that SMART disk health tests are not enabled by default and recommended activating them immediately to catch drive failures early.

A few pain points emerged. One reviewer experienced a deep hibernation issue where the NAS became unresponsive after several days of inactivity, requiring a full power cycle. Another noted that the M.2 NVMe slots did not achieve expected Gen 4 performance in initial testing, possibly due to PCIe lane allocation or firmware optimization still in progress. Setup time for RAID arrays can stretch to 24 hours depending on drive size, though the system remains usable during synchronization.
