Synology DS223 vs UGREEN NASync DXP4800 Plus

UGREEN NASync DXP4800 Plus, by a wide margin: four bays against two, expandable memory up to 64 GB, RAID 5 and RAID 6, NVMe storage pools and a processor that runs Docker and virtual machines. Synology DS223 wins mainly on price and noise.

Room to grow. Synology DS223 is a two-bay ARM box capped at 2 GB of memory and 40 TB raw. UGREEN NASync DXP4800 Plus is a four-bay x86-64 machine expandable to 64 GB of memory with a 144 TB raw ceiling and two extra NVMe slots.

Only UGREEN NASync DXP4800 Plus. Its Intel Pentium Gold processor runs both, plus hardware transcoding for Plex. Synology DS223 uses a Realtek ARM chip, so Container Manager is not available.

Synology DS223, clearly, rated at 14.6 dB against up to 34 dB for UGREEN NASync DXP4800 Plus. The gap is largely the cost of running four drives and a more powerful processor instead of two.

Buyers who want a quiet, affordable two-bay NAS for backup and file sharing on Synology's mature DSM software, and who do not need more than two drives or the ability to run containers.

Buyers who want four bays, room to grow the array to 144 TB raw, memory expandable to 64 GB, faster-than-Gigabit networking, and a processor that can host Docker containers and virtual machines.
