Overview

Synology's DS225+ arrives as the replacement for the DS224+, and the listing positions it squarely in the Plus series two-bay category. The processor is an Intel Celeron J4125 quad-core, paired with 2GB of non-ECC DDR4 SODIMM memory as standard. What separates this listing from a bare enclosure is the storage: two 6TB hard drives come in the box for 12TB total, sold as a best-price bundle. That framing suits buyers who want a working NAS without separately sourcing disks and cross-checking compatibility lists first.

Connectivity reflects the generational update. Two RJ-45 LAN ports are built in — one at 2.5 GbE, one at 1 GbE — which gives the unit a faster ceiling than the single-gigabit arrangement common to older two-bay boxes. Owners planning to grow into the hardware will note the memory ceiling of 6GB, reached by adding the supported D4NS01-4G module to the existing 2GB. Drive flexibility improved too. Since DSM 7.3 the DS225+ accepts third-party drives, removing a constraint that shaped earlier purchasing decisions. The included hard drives themselves come from well-known manufacturers and may be new old stock: produced earlier, but described as brand new, unused, and in perfect condition. Buyers trading cost against drive vintage should weigh that detail carefully before committing.

Frequently Asked Questions

The DS225+ is positioned as the new model of the 2-Bay Plus series, built around the Intel Celeron J4125 quad-core processor and adding a 2.5 GbE LAN port alongside a 1 GbE port.
Two 6TB hard drives ship with the unit, sourced from well-known manufacturers. They may be new old stock — produced some time ago but brand new, unused, and in perfect condition.
Yes. The standard 2GB non-ECC DDR4 SODIMM can be expanded to 6GB by adding the supported D4NS01-4G module, giving a 2GB plus 4GB configuration.
No. Since DSM 7.3, the DS225+ is compatible with third-party drives, so replacement and expansion disks are not limited to a single vendor's lineup.
Yes, partly. One of the two RJ-45 ports runs at 2.5 GbE while the second runs at 1 GbE, so a single connection can exceed gigabit speeds.
No. The DS225+ ships with 2GB of non-ECC DDR4 SODIMM memory, and the supported 4GB upgrade module follows the same non-ECC specification.
