The Synology DS225+ is a two-bay, diskless NAS enclosure sitting at number seven in this guide. Per the listing we pulled, it costs £373.99 and carries 4.3 stars from 208 ratings. What makes it worth reading closely is what the listing does not say: the name, the bullets and the specification fields supplied here never state a maximum capacity in TB. No drive is named and none is included — the size is listed as Diskless — so the one number a NAS buyer normally anchors on is simply absent, and Synology instead points you at its own compatibility list in the very first bullet.

What the listing does state is checkable. The network figure is Gigabit connectivity; no 2.5GbE or 10GbE port appears in any of the fields we have. The processor is an Intel Celeron J4125 quad-core, memory is 2 GB non-ECC DDR4 SODIMM upgradeable to 6 GB (2 GB + 4 GB), and the warranty is three years from the manufacturer. Two fields in the same listing pull against each other: Mounting Type reads Rack Mount, while Item Dimensions read 45 x 36 x 30 cm and Item Weight reads 1.2 kg. For the per-bay count this guide keeps running, Synology's declared 36TB across two bays works out at 18TB per bay, against the 28TB to 40TB per bay that the UGREEN listings imply for the same disk. Everything on this page comes from the Amazon listing — we have not tested this unit.

## Questions people ask

**How many bays does the Synology DS225+ have?**

Two. The Synology listing names it the 2-Bay NAS DS225+, and it ships diskless, so drives are bought separately.

**Does the Synology DS225+ come with hard drives?**

No. The size is listed as Diskless, and the first bullet states that the DS225+ requires compatible drives and refers you to the Synology compatibility list.

**What processor and memory does the Synology DS225+ use?**

The Synology listing gives an Intel Celeron J4125 quad-core processor, 2 GB non-ECC DDR4 SODIMM by default, upgradeable to 6 GB (2 GB + 4 GB), with support for the D4NS01-4G memory module.

**What network connection does the Synology DS225+ have?**

The item highlight lists Gigabit connectivity. No 2.5GbE or 10GbE port is named anywhere in the Synology listing fields we have.

**What is the maximum capacity of the Synology DS225+?**

The name, bullets and specification fields in this Synology listing do not state a maximum capacity in TB. The only drive-related reference is the compatibility list the ad points to.

**Is the Synology DS225+ rack mountable?**

The listing's Mounting Type field says Rack Mount, but the same listing gives item dimensions of 45 x 36 x 30 cm and an item weight of 1.2 kg, so that field does not sit easily with a two-bay desktop box.
