Data from the official Synology and UGREEN sites.
2026 verdict
For a 2-bay NAS you plan to fill with containers and a media server, the UGREEN NASync DXP2800 is the stronger pick of these two.
It ships with far more memory and a newer low-power Intel chip, adds two M.2 NVMe slots that can hold an all-flash pool for apps and databases, and is the better reviewed of the pair, while both share the same two-bay layout, hardware transcoding, Docker, virtual machines, Plex support and a 2.5 GbE port. The Synology DS225+ answers with a three-year warranty against two, the mature DSM platform and Hybrid RAID, which puts mismatched drive sizes to work. Buy the UGREEN NASync DXP2800 for a first home server with room to grow, and the Synology DS225+ if you want DSM's app catalog, Synology's support and the extra year of cover.

What the differences mean
Memory
The UGREEN NASync DXP2800 starts with 8 GB of DDR5 and can be upgraded to 16 GB, while the Synology DS225+ starts with 2 GB and caps at 6 GB. That headroom decides whether several containers or a virtual machine can run at once without the NAS swapping.
Fast storage for apps
The UGREEN NASync DXP2800 has two M.2 NVMe slots that can form a storage pool of their own, so apps, databases and photo indexing can live on solid-state drives. The Synology DS225+ has no M.2 slot, so everything shares the two hard drives.
Processor generation
The UGREEN NASync DXP2800 runs Intel's newer N100 and the Synology DS225+ the older Celeron J4125. Both are quad-core x86 chips with hardware transcoding, so the gap shows up in efficiency and future support more than in day-to-day file serving.
RAID flexibility
Synology's Hybrid RAID on the DS225+ can use drives of different sizes and lets you grow the array by swapping one disk at a time. The UGREEN NASync DXP2800 relies on standard mirroring; with two bays, neither can offer parity RAID.
Warranty
The Synology DS225+ carries a three-year warranty and the UGREEN NASync DXP2800 two, the clearest long-term point in Synology's favour on a machine meant to run for years.
Which one to buy if
- you want to run several containers or a virtual machine at once
The UGREEN NASync DXP2800 ships with 8 GB of DDR5, upgradable to 16 GB, where the Synology DS225+ stops at a 6 GB ceiling.
- your apps and photo library should live on solid-state storage
Only the UGREEN NASync DXP2800 has M.2 NVMe slots, and they can hold a fast pool of their own next to the hard drives.
- you already know Synology DSM or depend on its app catalog
The Synology DS225+ brings the mature DSM platform, Hybrid RAID and the longer warranty to the same two-bay size.
- the longest warranty and steady, well-documented software matter most
The Synology DS225+ is the more affordable of the two and backs the hardware for three years instead of two.

What owners say
Owners of the UGREEN NASync DXP2800 describe a first NAS that just works: quick setup, a friendly UGOS Pro interface, and built-in Photos and media apps good enough that several of them dropped a paid cloud subscription for it. They run Plex and Immich on the N100 with hardware transcoding without strain, keep apps and databases on the two M.2 NVMe drives while hard drives hold the media, and one moving from an older two-bay reports backups dropping from hours to under one. Value comes up repeatedly, with buyers noting more memory and a stronger processor than rival two-bay units. The complaints are a still-growing app catalog, some Docker troubleshooting for newcomers, and a minority who hit drive dropouts or a faulty M.2 slot.
Frequently Asked Questions
Which is better overall: Synology DS225+ or UGREEN NASync DXP2800?
The UGREEN NASync DXP2800, for most home buyers. It offers far more memory, two M.2 NVMe slots that can hold apps on their own, a newer low-power chip and the better owner feedback of the pair, while the Synology DS225+ counters with the DSM software, Hybrid RAID and a three-year warranty.
What is the biggest difference between the Synology DS225+ and the UGREEN NASync DXP2800?
Upgrade room. The UGREEN NASync DXP2800 starts with 8 GB of DDR5 and two M.2 NVMe slots, while the Synology DS225+ starts with 2 GB, tops out at 6 GB and has no M.2 slot, so containers and virtual machines have much less to work with.
Do the Synology DS225+ and the UGREEN NASync DXP2800 both run Plex and Docker?
Yes. Both are quad-core x86 NAS with hardware transcoding, so Plex can convert video in hardware and Docker containers are supported on either, along with virtual machines, Btrfs snapshots and a 2.5 GbE port.
Which one has more room to grow?
The UGREEN NASync DXP2800. Its memory can be upgraded to 16 GB against 6 GB on the Synology DS225+, it adds two M.2 NVMe slots with their own storage pool, and it supports more total raw capacity in its two bays.
Who should buy the Synology DS225+?
Buyers who want the Synology DSM platform and its established app catalog, Hybrid RAID for mismatched drives, the longer three-year warranty and the lower price, and who do not plan to stack containers or virtual machines.
Who should buy the UGREEN NASync DXP2800?
First-time NAS owners and home-server builders who want strong hardware for the money: 8 GB of DDR5, two M.2 NVMe slots, a newer N100 with hardware transcoding and a friendly operating system for Plex, Immich and Docker.
