Synology DiskStation DS725+ 2-Bay Plus Series NAS

The Synology DiskStation DS725+ is a scalable 2-bay desktop NAS with an AMD Ryzen processor, 4GB ECC memory, 2.5GbE networking, dual M.2 NVMe slots and expansion support for up to seven drives.

Product Description

The Synology DiskStation DS725+ is a compact network attached storage system designed for centralised file storage, business backup, collaboration, private-cloud access and surveillance.

It is powered by an AMD Ryzen R1600 processor with two cores, four threads, a 2.6GHz base frequency and turbo speeds of up to 3.1GHz.

The system includes 4GB of DDR4 ECC SODIMM memory and supports expansion to a maximum of 32GB using compatible Synology memory modules.

Two hot-swappable SATA drive bays support compatible 3.5-inch SATA hard drives or 2.5-inch SATA solid-state drives.

Two built-in M.2 2280 NVMe slots can be used for compatible SSD caching or supported M.2 storage pools without occupying the main SATA drive bays.

One 2.5GbE network port and one Gigabit Ethernet port provide flexible network connectivity and failover support. Synology lists sequential performance of up to 276MB/s read and 224MB/s write under its specified test conditions.

Storage capacity can be expanded from two to seven SATA drive bays by connecting one optional Synology DX525 Expansion Unit through the dedicated USB Type-C expansion port.

Synology DiskStation Manager provides tools for file sharing, backup, synchronisation, collaboration, photo management, virtualisation and surveillance.

Surveillance Station includes two default device licences and supports up to 40 compatible IP cameras, depending on the recording configuration and active workloads.

The DS725+ is supplied without storage drives, M.2 SSDs, memory upgrades or the DX525 Expansion Unit.

Specifications

Compatibility Note

Confirm that all storage drives, M.2 SSDs, memory modules and expansion accessories are officially compatible with the Synology DS725+ before ordering.

The DS725+ supports:

• Up to two compatible internal SATA drives
• Up to two compatible M.2 2280 NVMe SSDs
• One Synology DX525 Expansion Unit
• Synology D4ES04-4G, D4ES03-8G and D4ES03-16G memory modules

M.2 storage pools require supported Synology-verified NVMe SSDs. The M.2 slots do not support hot-swapping.

RAID 5, RAID 6 and RAID 10 require the optional DX525 and the appropriate number of compatible drives.

The USB Type-C port is intended for the DX525 Expansion Unit and is not a general-purpose USB-C port.

When both memory slots are populated, the installed memory modules must be identical and use the same model number.

Storage capacity will be lower than the combined manufacturer-rated drive capacity because of RAID, formatting, system partitions and file-system data.

RAID can protect against selected drive failures but does not replace a separate backup.

What’s in the Box

• 1 × Synology DiskStation DS725+ Main Unit
• 1 × Accessory Pack
• 1 × AC Power Adapter
• 1 × AC Power Cord
• 2 × RJ-45 LAN Cables

Storage drives, M.2 SSDs, memory upgrades and the DX525 Expansion Unit are not included.

Warranty

Three-Year Synology Limited Hardware Warranty

Sustainability

The Synology DS725+ is RoHS compliant and supports memory, M.2 storage and drive-bay expansion, helping the system adapt to changing storage requirements without replacing the complete NAS.
