High-spec 4-bay NAS with 10GbE, but only if you need the speed

UGREEN NASync DXP4800 Plus is worth buying if you want a fast, modern 4-bay NAS with 10GbE, dual 2.5GbE, NVMe slots and HDMI output at a current all-time-low price of £559.99. At 4.5/5 from 120 reviews, it looks well received, and the spec sheet is unusually strong for a diskless desktop NAS at this price.

First impressions

The DXP4800 Plus is aimed at users who want more than basic file sharing. You get a 4-bay chassis, Intel Pentium Gold 8505 5-core CPU, 8GB DDR5 RAM, a 128GB SSD, one 10GbE port, one 2.5GbE port, two M.2 NVMe slots and 4K HDMI. That combination makes it more interesting than many entry-level NAS boxes, especially if you plan to run media, backups and a few services from the same device.

What do the key specs mean in practice?

The headline feature is network speed. A 10GbE port can make a real difference for large photo libraries, video editing workflows and fast local backups, while the 2.5GbE port gives you a more flexible second network option. The two M.2 NVMe slots should also help with cache or storage-tiering use cases, which is useful if you want snappier access to frequently used files.

The 4-bay design matters just as much. Compared with a 2-bay NAS, it gives you more room to grow and more RAID flexibility. UGREEN claims up to 144TB capacity, which is far beyond what most home users will need, but it does show the platform is built for serious storage expansion.

How does it perform?

On paper, this is a strong performer for a home lab or media server. The Pentium Gold 8505 is not a high-end workstation chip, but the 5-core design is a sensible match for a NAS that prioritises storage, network throughput and light multitasking over heavy compute. The included 8GB DDR5 RAM is a decent starting point, though power users running multiple containers, media indexing or virtualisation workloads may want more headroom depending on what the platform allows.

UGREEN also claims you can back up 1GB in less than a second using either the 10GbE network port or the 10Gbps USB ports. That is the kind of transfer speed that will matter if you are moving large video files, disk images or multi-hundred-gigabyte photo archives. The 4K HDMI output adds local display support, which is handy for setup or direct playback.

Is the build and feature set good?

The feature mix is excellent for the money: 4 bays, DDR5 RAM, NVMe slots, fast Ethernet and HDMI in one box. The 128GB SSD is a useful inclusion for the system itself, and the diskless design means you can choose your own drives rather than being locked into a bundled configuration.

The big strength here is flexibility. UGREEN positions it as a private cloud with encryption, permission management, remote access, automatic backups and RAID support. It also includes AI-powered photo features that can recognise faces, scenes, objects and locations, plus duplicate removal. If you have a large family photo archive, that could be genuinely useful.

What are the weaknesses?

The biggest downside is that this is a diskless NAS at £559.99, so the real cost rises once you add drives. If you need a simple, low-cost 2-bay unit, this is overkill. It is also a newer product than many mainstream NAS rivals, so ecosystem maturity and long-term software confidence matter more here than they would with a more established brand.

Another warning is that the strongest features only matter if your network and workflow can use them. A 10GbE NAS will not feel magical on a basic gigabit setup, and the AI photo tools are only useful if you actually want that style of library management.

Is it good value for money?

At £559.99, down 10% from the £619.99 RRP, it is priced aggressively for a 4-bay NAS with 10GbE, 2.5GbE, dual NVMe slots and HDMI. The current price is also the all-time lowest, which makes this one of the better moments to buy if you were already considering it.

How does it compare to alternatives?

Against the Synology DS223J at £179.97, the UGREEN is in a completely different class: more bays, faster networking and far more expansion potential, but also a much higher upfront cost. Compared with the Synology DS224+ at £510.75, the UGREEN is slightly more expensive yet offers 4 bays instead of 2, plus 10GbE, 2.5GbE and NVMe slots. The Synology DS224+ at £688.05 is pricier still, so the UGREEN looks competitive if raw hardware matters more than brand ecosystem.

If you want the best hardware spec per pound, the DXP4800 Plus has a strong case. If you want the most established software platform, Synology still has the safer reputation.

Bottom line

This is a well-specced 4-bay NAS for users who care about speed, expandability and modern connectivity. It makes the most sense for Plex libraries, large backups, home lab storage and private-cloud setups where 10GbE and NVMe support will actually be used.
