UGREEN NASync DXP2800
5.9/10verdict: wait for dealThe DXP2800 is for home users and small setups that want a quiet two-bay NAS with 2.5GbE and two NVMe slots. It suits people happy to put up with a young operating system and thin documentation. It is a weaker fit for anyone who wants a mature app ecosystem or plans to run several virtual machines.

TERRAMASTER F2-425
5.6/10verdict: wait for dealThe TerraMaster F2-425 is for people who want a two-bay NAS with 2.5GbE for file storage, backups and light media serving. It suits buyers who will add their own SATA drives and run a few containers or a Plex server. It is less suited to anyone who needs more than two bays, M.2 cache or a lot of memory headroom.

UGREEN NASync DH4300 Plus
5.1/10verdict: wait for dealThe UGREEN NASync DH4300 Plus is a four-bay SATA NAS for people who want a quiet, low-power file server with some Docker containers. It suits buyers who will be happy with 8GB of fixed memory and a single 2.5GbE port. It is a poor fit for anyone who needs virtual machines, M.2 cache or Intel Quick Sync.

Synology DiskStation DS124
5.0/10verdict: wait for dealThe DS124 is for people who want a very simple, single-drive NAS running full Synology DSM. It suits a home or small office that needs network file storage, Btrfs snapshots or Surveillance Station. It does not suit anyone who needs RAID, redundancy or heavy workloads.

Synology DiskStation DS423
4.8/10verdict: skipThe DS423 is for people who want a four-bay Synology NAS for file storage, shared folders and backups. It suits those who value DSM and Btrfs more than raw hardware power. It is less suited to anyone planning containers, virtual machines or video transcoding.

Synology DiskStation DS225+
4.5/10verdict: skipThe DS225+ suits home and small-office buyers who want Synology's DSM software for file sharing, backups, photos and a few cameras on two drives. Its 2.5GbE port and mature app set fit light, dependable storage duties. Media servers that need hardware transcoding, heavy container or VM use, and anyone wanting NVMe cache are poorly served by its 2019-era CPU, 6 GB RAM ceiling and lack of M.2 slots.

UGREEN NASync DH2300
4.4/10verdict: skipThe UGREEN NASync DH2300 is for people who want a simple, low-power two-bay box for backups, photos and file storage. It suits a first NAS buyer who will use UGREEN's own UGOS Pro apps and doesn't need containers or virtual machines. Homelabbers who want Docker, more memory or faster than 1GbE networking should look at something else.

5.0/10verdict: wait for dealThe DS223j is for people who want a simple two-bay NAS for file storage and backup. It suits anyone who values easy DSM setup, quiet running and low power draw over raw performance. It is a poor fit for memory-hungry workloads or anyone who needs more than a single 1GbE connection.
