Description
The Synology DiskStation DS725 redefines compact storage efficiency, offering a robust 2-bay solution that scales with your growing data needs. Powered by an AMD Ryzen R1600 dual-core processor and equipped with 2.5GbE networking, this NAS delivers sequential read speeds exceeding 276 MB/s. Whether you are centralizing backups, hosting a private cloud, or managing a surveillance network, the DS725 provides the stability of ECC memory and the speed of dual M.2 NVMe slots in a desktop-friendly form factor.
This product is for:
- Creative Professionals: Photographers and videographers requiring a fast, centralized repository for high-resolution assets with 2.5GbE throughput.
- Small Business Owners: Teams looking for a secure, on-premises private cloud that supports multi-endpoint backup and seamless file synchronization.
- IT Enthusiasts: Users who demand hardware flexibility, including RAM expansion up to 32GB and NVMe SSD caching for virtual machines.
- Surveillance Operators: Security-conscious users needing a reliable NVR capable of managing up to 40 IP cameras via Synology Surveillance Station.

- Max Raw Capacity: Up to 140 TB with expansion unit
Operating the DS725 is a seamless experience thanks to the intuitive DiskStation Manager (DSM) ecosystem. The inclusion of ECC (Error Correction Code) memory ensures data integrity by automatically detecting and fixing bit errors, a critical feature for long-term archival. The dual M.2 NVMe slots allow users to boost I/O response times without occupying the main drive bays. During heavy workloads, the 92mm system fan remains remarkably quiet at 17.9 dB(A), making it an ideal companion for quiet office environments.
Compared to entry-level 2-bay models, the DS725 stands out with its Ryzen-based architecture and 2.5GbE networking, which significantly reduces file transfer bottlenecks. While the DS224+ offers basic home features, the DS725 provides professional-grade expandability, allowing users to add five additional drives via the DX525 expansion unit. Its support for up to 32GB of RAM and NVMe storage pools positions it closer to the performance tier of the 4-bay DS923+, but in a more space-efficient 2-bay chassis.
Q&A:
- How much storage can the DS725 handle?
The DS725 supports two internal drives, but can be expanded to a total of 7 drives using a Synology DX525 expansion unit, reaching a maximum raw capacity of 140 TB.
- Does the DS725 support 2.5GbE networking?
Yes, it features a built-in 2.5GbE RJ-45 port for high-speed data transfers, alongside a standard 1GbE port for network redundancy or management.
- Can I upgrade the RAM on this model?
The unit comes with 4GB of DDR4 ECC memory and features two SODIMM slots, supporting a maximum total capacity of 32GB (16GB x 2).
- What is the benefit of the M.2 NVMe slots?
The two internal M.2 2280 slots can be used for SSD caching to accelerate HDD performance or to create high-speed NVMe storage pools for frequently accessed data.
- Is the DS725 suitable for video surveillance?
Absolutely. It can manage up to 40 IP cameras and integrates perfectly with Synology Surveillance Station for professional-grade security monitoring.
