Ugreen NASync DXP4800 Pro review: This superbly built NAS offers a powerful hardware package but comes up short in the app department

Ugreen is rapidly gaining a strong reputation in the NAS market with its ever-expanding range of desktop appliances. And the latest DXP4800 Pro focuses on demanding home and small office users who want plenty of power and performance for their money. Stepping up as Ugreen's flagship 4-bay appliance, it takes everything we liked about the two-year-old DXP4800 Plus and gives it a performance boost.

The Gen12 5-core Intel Pentium Gold 8505 CPU in the Plus model gets replaced with a more modern Gen13 6-core Core i3-1315U offering four efficient plus two multi-thread performance cores and a top Turbo frequency of 4.5GHz. Memory stays the same at DDR5, but those with deep pockets can upgrade the base 8GB to 96GB – the maximum supported by this CPU.

Along with four front drive bays, you have a pair of M.2 NVMe SSD slots lurking in the base, and it's worth noting these are the faster PCIe Gen4 variety. Network port choices remain the same, although these are superior to a lot of the competition as the appliance sports 2.5GbE and 10GbE multi-Gigabit ports.

Ugreen NASync DXP4800 Pro review: Build quality and hardware features

No cheap plastic chassis here as the DXP4800 Pro is clothed in a sleek and sturdy aluminium alloy shell. SATA hard disks slip easily into the clever telescopic tool-free carriers, which also have mounting holes for SFF SATA SSDs.

The two M.2 slots are easy to access as the cover is spring-loaded, and you'll find two SO-DIMM slots next to them with the base 8GB of memory provided on one stick. General cooling is handled efficiently by a big rear 14 cm diameter fan behind a magnetic dust cover, and we found the appliance to be pleasingly quiet.

The appliance offers plenty of other interfaces with 10Gbps USB-C 3.2 and USB-A 3.2 at the front next to an SD Card reader slot. A peek around the back reveals one 5Gbps USB-A 3.2 and two USB-A 2.0 ports, while 4K 60Hz video from the CPU's embedded Intel UHD Graphics GPU is piped through to an HDMI 2.0 port.

We don't often comment on packaging, but Ugreen gets praise for all the extra bits and prices it includes in the box. The external PSU comes with a UK plug lead, and the accessory box contains two Ethernet cables, a screwdriver, and a full set of screws for SFF drives, two carrier locking keys, two adhesive silicon heat pads for M.2 devices, and even a Ugreen-branded HDMI cable.

Ugreen NASync DXP4800 Pro review: Deployment and UGOS apps

For testing, we fitted four 4TB Seagate IronWolf NAS HDDs, which were accepted without any problems, as unlike Synology, Ugreen doesn't have any drive restriction policies. Installation is a breeze as Ugreen's discovery web portal found the appliance on our network, initialised it, and downloaded the latest UGOS software.

The UGOS web console is nicely designed and aids storage pool creation by offering sage advice on the various RAID options. We chose the recommended RAID5 volume and were prompted to create personal and shared folders and configure remote access, which creates a unique Ugreenlink ID and secure web link.

During volume creation, you can choose from the Ext4 and Btrfs file systems, with the latter the preferred choice if you want snapshots, storage space quotas, and higher levels of data integrity protection. We also noted that the Samba file sharing service is disabled by default, which we think is a good security measure.

UGOS is light on apps as it only offers 29 for the DXP4800 Pro – well short of the huge range offered by Qnap and Synology. Data protection features start with the Snapshot app, which supports manual and scheduled snapshots on user and shared network folders stored in Btrfs volumes, but Ugreen has yet to update this to support iSCSI LUNs.

The Sync & Backup app secures local data to a remote Ugreen NAS and vice versa, and also supports Rsync-compliant servers. The app has a download link for Ugreen's NAS Windows and macOS desktop tool for creating sync tasks that secure selected data to a shared folder and update it in real time, while the Cloud Drives app provides file syncing for seven cloud storage services, including OneDrive and Google Drive.

The Security Manager app provides real-time and scheduled anti-malware protection with quarantining. Virtualization is on the menu with the Docker app running lightweight containers and the Virtual Machine app providing full hypervisor services.

Ugreen NASync DXP4800 Pro review: 10GbE performance

For performance testing, we hooked the NAS up to the lab's 10GbE network and mapped a share to a Dell PowerEdge Windows Server 2025 host. UGOS now supports 9000-byte Jumbo frames, and with these enabled, we saw good NAS speeds with Iometer reporting sequential read and write rates of 9.2Gbits/sec and 8.1Gbits/sec

For our real-world tests, copies of a large 25GB test file between the appliance and server delivered sustained read and write rates of 3.2Gbit/sec and 2.7Gbits/sec while backing up a 22.4GB folder with 10,500 small files averaged a reasonable 1.5Gbits/sec. Ugreen added the SAN Manager app a while ago, and moving to IP SANs saw a 500GB iSCSI target deliver Iometer read and write rates of 9.2Gbits/sec and 7.5Gbits/sec.

For cache testing, we fitted two 480GB Kingston M.2 NVMe SSDs and assigned them to our data volume as a mirrored read/write cache. This made noticeable improvements to random write operations with our NAS share and iSCSI LUN, seeing respective speed increases of 123% and 120%.

Ugreen NASync DXP4800 Pro review: Is it worth it?

With Ugreen currently offering the NASync DXP4800 Pro for £620 including VAT, it compares very well on value with the competition. Synology's DS925+, for example, costs a shade under £600 but only supports DDR4 memory, has dual 2.5GbE ports, is powered by a pensionable AMD Ryzen 1500B CPU, and doesn't offer a 10GbE upgrade option.

Ugreen's build quality is also vastly superior, but there's a lot of work to be done with the UGOS software before it can match the incredible range of apps, services, security, and data protection features offered by Synology's DSM and Qnap's QuTS Hero. The DXP4800 does deliver an impressive hardware package for the price, though, and if you can cope with the basic range of apps, is a great choice for home and office users seeking a powerful NAS appliance with great 10GbE performance.
