UGREEN NASync DXP4800 Plus Review: Power with Caveats
Digging into months of real-world feedback, the UGREEN NASync DXP4800 Plus 4-Bay Desktop NAS emerges as a hardware powerhouse with a surprisingly attractive price point, but not without quirks in its operating system. Across Reddit, Trustpilot, and independent long-term tests, users repeatedly praise its CPU muscle, 10GbE networking, and broad drive compatibility, yet caution that the bundled UGOS Pro software still lacks some advanced storage features. Based on aggregated sentiment, it scores 8.6/10 for hardware, but dips to 7.8/10 overall due to OS limitations.
Quick Verdict: Conditional buy — excellent for power users comfortable with Docker or alternative OS installs, but beginners seeking polished native apps may face a learning curve.

| Supports up to 136TB with wide HDD/SSD compatibility | Occasional drive recognition issues reported |
| Expandable DDR5 RAM up to 64GB | OS language inconsistencies in menus |
| Quiet operation (29–34 dB) | Extra setup needed for alternative OS installs |
| Aluminum chassis with tool-less drive bays | High-capacity HDDs can be noisy |
Claims vs Reality
Marketing touts “blazing-fast 1250 MB/s transfers” via dual multi-gigabit ports. While officially rated at this speed, long-term testers confirm the claim in practical use. Galaxus reported hitting “an average of 8.16 gigabits per second – or 1.02 gigabytes per second – copying a large file via a 10-gigabit switch,” a figure echoed by Fakespot reviewers who “got very fast speed with my NAS.”
Another bold claim is “professional data security,” implying full encryption. Digging deeper, multiple users note UGOS Pro currently lacks volume-level encryption, meaning stolen drives could be read by third parties. As Galaxus puts it: “The biggest problem is undoubtedly that UGOS Pro doesn’t currently offer volume encryption.”
UGREEN markets “straightforward dedicated app” management across platforms. Here, reality aligns well: the mobile app earns praise for capability. Galaxus observed it can “do almost anything… only a few applications and options can’t be controlled with it,” making it one of the better mobile NAS interfaces in this segment.
Cross-Platform Consensus
Universally Praised
The standout feature is hardware value. Reddit threads highlight the 12th-gen Pentium Gold CPU’s strong single-core score, while Galaxus stresses it “performs best in single-core tasks and second best in multi-core tasks” in its class. This translates to smoother Plex transcoding and faster Docker container performance. A verified buyer on Trustpilot noted: “Compared to the Synology 918+ this is a good machine… the OS is stable.”
Network throughput is another universal win. Even heavy media users benefit: Galaxus reported starting a film “without waiting seconds before it starts… transfer speed’s impressive.” Power users running VM workloads cite the dual Ethernet setup as transformative for backups and large media libraries.
Drive compatibility also earns wide praise. UGREEN supports Seagate, Toshiba, and WD without vendor lock-in. Fakespot reviewers call toolless drive insertion “great… easy to assemble and put into operation,” while Galaxus lauds being able to “put four 22TB Toshiba MG10s” into the retail sample without issue.
Common Complaints
The most consistent frustration is UGOS Pro’s incomplete feature set. Advanced users lament missing iSCSI target support and ZFS file system compatibility. A long-term tester observed that “Btrfs disables the copy-on-write feature” and noted “only a few native apps… thanks to Docker, it’s still possible to run anything” but with extra setup. Language display bugs — Dutch text appearing in German installs — add polish concerns.
Hardware-wise, a few users encountered drive recognition errors. Fakespot highlighted: “Two of the drives… would not be recognized and was throwing errors,” though this appears isolated and possibly tied to firmware versions.
Noise from high-capacity HDDs is another minor complaint. Galaxus warns “hard drives with larger storage capacities tend to be louder… an NAS doesn’t belong in the living room or bedroom either way.”
Divisive Features
The aluminum chassis and quiet cooling split opinions. Many love the premium feel and “faint breeze” noise level; others, like Galaxus, still swapped in a Noctua fan for “no audible airflow.” Some call the fan mod unnecessary, given acceptable temps of “40–47°C HDD” under load.
Docker support is a double-edged sword. Experienced users revel in installing anything — Plex, Jellyfin, niche tools — while beginners face a steeper curve. As one Fakespot reviewer put it: “If a supported app isn’t available then Docker will likely get you sorted… still the lack of iSCSI LUN support can be a problem for advanced users.”
Trust & Reliability
Trustpilot entries and long-term reports show no signs of scam behavior. Units arrive as described, with Galaxus noting over a year of stable hardware performance after initial beta software hiccups. Durability stories include multiple RAM and SSD upgrades without issue and sustained high-speed transfers.
Firmware updates have incrementally improved UGOS Pro, adding languages and smoothing Docker integration. However, the missing encryption feature remains unresolved as of mid-2025, keeping cautious enterprise buyers on the fence.
Alternatives
The main rivals mentioned are Synology DS925+, Asustor Lockerstor 4 Gen 3, and QNAP TVS-h474. Galaxus’ comparison table shows UGREEN undercutting Asustor and QNAP by more than half while matching or beating them in CPU single-core performance and offering 10GbE like QNAP. Synology lags in raw specs and limits drive choice, but retains a more mature OS with richer native apps.
For users prioritizing polished software and deep ecosystem integration, Synology still holds appeal. For those chasing maximum hardware per euro/dollar, UGREEN’s offering is hard to beat.
Price & Value
eBay listings show recent UK pricing at £509.99 after discount, down from £599.99. This positions it as a midrange NAS with high-end throughput. Galaxus pegs EU retail around €650, noting that Asustor/QNAP equivalents cost €1,350–€1,400. Community tips include waiting for periodic UGREEN site discounts and budgeting for RAM upgrades to unlock full performance.
Resale value is untested due to the product’s recent mainstream launch in 2025, but broad drive compatibility should help maintain relevance.
FAQ
Q: Can I run Plex on the DXP4800 Plus without issues?
A: Yes — while UGOS Pro lacks a native Plex app, Docker installation works well. Users report smooth transcoding thanks to the iGPU, even with multiple 4K streams.
Q: Is drive encryption supported?
A: Not currently at the volume level in UGOS Pro. Encrypted backups are possible, but stolen drives could be read.
Q: How noisy is it in a home office?
A: With stock fan and HDDs, noise is a faint breeze at 29–34 dB. High-capacity 7,200 RPM drives add audible chatter.
Q: Can I install another OS like TrueNAS?
A: Yes — disable “watch dog control” in BIOS and adjust boot order. Backup the UGOS Pro system image before wiping.
Q: Does it support ZFS?
A: No, UGOS Pro does not support ZFS. Alternative OS installs can enable it.
Final Verdict: Buy if you’re a power user ready to leverage Docker or install an alternative OS, especially for high-speed media serving and backups. Avoid if you require polished, feature-complete native apps out of the box. Pro tip from community: Upgrade RAM early — “the RAM upgrade would probably be justified” — to fully exploit 10GbE transfers and multitasking potential.
