2026 verdict
For a quiet, proven four-bay NAS, the Synology DS425+ is the better pick of these two.
It pairs Intel hardware transcoding with Synology's mature DSM software, a three-year warranty and a much lower noise rating, and it keeps hybrid RAID and the full Synology app catalogue. The UGREEN NASync DXP4800 Plus is the faster machine on paper and the more expandable one: a five-core Pentium Gold, 8 GB of DDR5 that can grow to 64 GB, a 10 GbE port, HDMI and an SD card reader. Choose the Synology DS425+ if you want a set-and-forget home server, and the UGREEN NASync DXP4800 Plus if your bottleneck is the network or you plan to run containers and virtual machines with room to grow.

What the differences mean
Memory headroom
The Synology DS425+ ships with 2 GB and tops out at 6 GB, which is fine for file sharing and a media server but tight once containers and a virtual machine run together. The UGREEN NASync DXP4800 Plus starts at 8 GB of DDR5 and accepts up to 64 GB, so it is the one to pick if you intend to layer services on the NAS over time.
Network speed
The UGREEN NASync DXP4800 Plus carries a 10 GbE port next to its 2.5 GbE port, while the Synology DS425+ offers one 2.5 GbE and one Gigabit port. For video editing off the array or bulk copies, the UGREEN has the higher ceiling, provided the switch and the client machine can feed it; for ordinary home backups the Synology's 2.5 GbE is already beyond what most broadband and Wi-Fi setups use.
Processor
A five-core Intel Pentium Gold 8505 sits in the UGREEN NASync DXP4800 Plus and a four-core Celeron J4125 in the Synology DS425+. Both are x86-64 with integrated graphics, so both transcode in hardware, but the newer Pentium has more headroom for photo indexing, containers and virtual machines.
Ports and local output
The UGREEN NASync DXP4800 Plus adds 4K HDMI, an SD card slot and a 10 Gbps USB-C port, which makes it a workstation companion for photographers and a machine you can plug into a television. The Synology DS425+ has two USB-A ports and no video output, so it is managed from a browser as Synology intends.
Software and RAID flexibility
The Synology DS425+ runs DSM, a long-established platform with Synology Hybrid RAID, iSCSI and rsync on its feature list. The UGREEN NASync DXP4800 Plus runs UGOS Pro, which is much newer, has no hybrid RAID mode and leaves iSCSI and rsync undocumented in this catalog, so the Synology is the safer bet for mixed drive sizes and unusual backup setups.
Noise and warranty
Synology quotes 21.6 dB for the DS425+ and UGREEN 34 dB for the NASync DXP4800 Plus, a gap you would notice if the unit lives in a room you use. The Synology also carries a three-year warranty against two years for the UGREEN.
Which one to buy if
- the NAS will sit in a living room or a home office
The Synology DS425+ is rated at 21.6 dB and backed by a three-year warranty, where the UGREEN NASync DXP4800 Plus is quoted at 34 dB.
- you edit video over the network or move very large files daily
Only the UGREEN NASync DXP4800 Plus offers a 10 GbE port, and its 64 GB memory ceiling keeps the array fed.
- you want to run containers and virtual machines for years
The combination of a five-core Pentium Gold and DDR5 expandable to 64 GB gives the UGREEN NASync DXP4800 Plus far more room than the Synology DS425+'s 6 GB ceiling.
- you are a photographer offloading cards
The UGREEN NASync DXP4800 Plus has a built-in SD card reader and HDMI output, neither of which the Synology DS425+ offers.
- you want the most predictable software and support
DSM is a mature platform with hybrid RAID, iSCSI and rsync, while UGOS Pro is considerably newer.

Frequently Asked Questions
Which is better overall: Synology DS425+ or UGREEN NASync DXP4800 Plus?
The Synology DS425+ is the safer overall choice for a home NAS: mature DSM software, hardware transcoding, hybrid RAID, a three-year warranty and a much quieter enclosure. The UGREEN NASync DXP4800 Plus wins on raw hardware, with a faster processor, a 64 GB memory ceiling, 10 GbE, HDMI and an SD card reader, so it is the better pick for network-bound work and heavier self-hosting.
What is the biggest difference between the Synology DS425+ and the UGREEN NASync DXP4800 Plus?
Expandability. The Synology DS425+ ships with 2 GB of memory and cannot go past 6 GB, while the UGREEN NASync DXP4800 Plus starts at 8 GB of DDR5 and accepts up to 64 GB. That ceiling, together with the UGREEN's 10 GbE port and faster Pentium Gold processor, is what separates the two machines.
Do the Synology DS425+ and the UGREEN NASync DXP4800 Plus both transcode video in hardware?
Yes. Both use Intel processors with integrated graphics, so both can transcode in hardware for Plex and similar media servers. The UGREEN NASync DXP4800 Plus has the newer and faster chip, but the Synology DS425+ handles the task comfortably.
Which one is quieter, the Synology DS425+ or the UGREEN NASync DXP4800 Plus?
The Synology DS425+ is quoted at 21.6 dB against 34 dB for the UGREEN NASync DXP4800 Plus. If the NAS has to live in a room you use, the Synology is the one that disappears into the background.
Who should buy the Synology DS425+?
Anyone who wants a four-bay NAS that is quiet, backed by a three-year warranty and managed through Synology's mature DSM software, with hardware transcoding, hybrid RAID and snapshots for a straightforward home server.
Who should buy the UGREEN NASync DXP4800 Plus?
Buyers whose limiting factor is the network or the memory: video editors working over 10 GbE, photographers who want an SD reader, and self-hosters planning containers and virtual machines who need more than a small memory ceiling.
