5.0/10verdict: wait for deal

The 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.

5.6/10verdict: wait for deal

The 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.
