Overview

Compact, fast and versatile

The Synology DS225+ is a 2-bay NAS ideal for demanding home users and small businesses. It combines performance, reliability and modern connectivity with its quad-core Intel Celeron J4125 processor and 2.5 GbE port. This compact enclosure (165 x 108 x 232 mm, 1.3 kg) delivers read speeds of up to 280 MB/s for fast back-ups, all in a discreet, expandable format.

Balanced, reliable architecture

Powered by a quad-core Intel Celeron J4125 processor running at 2.0 GHz to 2.7 GHz in Burst mode, the DS225+ provides a stable foundation for everyday tasks, multimedia and productivity. With 2 GB of soldered DDR4 RAM, expandable via a SODIMM slot up to 6 GB, it meets performance needs in a scalable way.

This configuration delivers stable transfer rates (~280 MB/s read, ~210 MB/s write) while keeping power consumption low (around 14 W idle and 26 W under load). So your back-ups remain fast without consuming too much power or generating too much noise.

High-speed connectivity

At the cutting edge of modern networking, the DS225+ offers a 2.5 GbE port and a 1 GbE port: a real plus over the previous model. This connectivity enables local transfers up to twice as fast, ideal for HD video, file synchronisation and network backup.

It also has two USB 3.2 Gen 1 (5 Gb/s) ports, on the front and rear, for connecting external drives or printers. Although the DS225+ does not offer an M.2 slot or PCIe port, it can accommodate the DX525 expansion module via USB-C, adding up to 5 bays as required.

    NAS Synology Avril2026

    The seller was the best of the best and really took the time to answer all our questions.

    We wanted to set up secure data management within our household, and this is truly the ideal solution for instantly backing up all the activity from our laptops. This model is very well suited for a home: fast, with two drives for added security, and high-performing.

    The physical installation is child’s play. Getting to grips with it and configuring the system takes a bit of time for someone who doesn’t really have experience with this type of equipment, but with a few tutorials you can get there easily.

    The quality/price ratio for the enclosure seems totally justified to us; this is a little less the case with the hard drives that go inside it: a bit expensive.

    That said, I really do recommend this product. It allows us to have peace of mind about our data and not fear technical problems with our devices.

    All is well

    These disks were intended for a NAS D225+. The products were well packaged and delivered on time. Getting started went without a hitch. Lots of tutorials available for Synology applications.
    I was looking for peace of mind with the supplier and the products, and I got both. Would recommend.
