Overview

The Synology DS225+ steps in as the replacement for the DS224+, and this bundle pairs the two-bay enclosure with 24TB of storage arriving as a matched pair of 12TB drives. What sets it apart in its tier is the pairing of an Intel Celeron J4125 quad-core processor with a 2.5 GbE network port — a combination that gives the unit more compute and faster wired connectivity than many entry-level two-bay boxes. It suits home users building a first serious storage hub and small offices that want a ready-to-run box without hunting down compatible drives separately.

On the construction and ownership side, the DS225+ keeps things flexible. Memory ships at 2GB of Non-ECC DDR4 SODIMM and climbs to 6GB using the supported D4NS01-4G module, so growth is possible without replacing the machine. Two RJ-45 ports handle networking: one 2.5 GbE and one 1 GbE. Since DSM 7.3, the platform accepts third-party drives, widening replacement options down the road. The bundled hard drives come from well-known manufacturers and may be new old stock — earlier production runs that the seller describes as brand new and unused — which is how the package reaches its lower price point.
