2026 verdict
Two bays or four? The UGREEN NASync DXP4800 Plus is the more capable NAS, with four bays, two NVMe slots, a 10 GbE port and a memory ceiling of 64 GB, against two bays and 6 GB on the Synology DS225+.
Its Intel Pentium Gold 8505 has hardware transcoding, it supports RAID 5 and RAID 6, and it adds 4K HDMI and an SD card slot. The Synology DS225+ is the lower priced, the quieter at 19.6 dB against 34 dB and carries a three-year warranty against two, and its DSM software is the more mature of the two platforms. Both run Docker, virtual machines and Plex, with Btrfs and snapshots. Pick the UGREEN NASync DXP4800 Plus for a big media library and fast networking, and the Synology DS225+ for a quiet two-bay box that just works.

What the differences mean
Bays and capacity
The UGREEN NASync DXP4800 Plus has four hot-swappable bays for up to 144 TB of raw capacity plus two M.2 NVMe slots that can act as a storage pool. The Synology DS225+ has two bays for up to 40 TB and no NVMe slots.
RAID
With four bays, the UGREEN NASync DXP4800 Plus supports RAID 5 and RAID 6, which tolerate a failed drive and give more usable space. The Synology DS225+ offers Synology Hybrid RAID with mirroring across its two bays.
Network speed
The UGREEN NASync DXP4800 Plus has a 10 GbE port and a 2.5 GbE port, while the Synology DS225+ has 2.5 GbE and 1 GbE. The 10 GbE port only pays off with a 10 GbE switch and computer.
Memory
The UGREEN NASync DXP4800 Plus takes DDR5 up to 64 GB from an 8 GB start. The Synology DS225+ has 2 GB and reaches 6 GB, which is thin for running containers and a virtual machine together.
Noise and warranty
The Synology DS225+ is rated 19.6 dB and the UGREEN NASync DXP4800 Plus 34 dB, a gap you would hear in a quiet room. The Synology DS225+ also has a 3-year warranty against 2 years.
Extra outputs
Only the UGREEN NASync DXP4800 Plus lists a 4K 60Hz HDMI output, an SD card slot and a 10 Gbps USB-C port. The Synology DS225+ has none of them.
