2-Bay Expandable Desktop NAS
Synology DS725neo+ Network Attached Storage
Compact and capable storage for home, small business and edge deployments, with an AMD Ryzen R1600 processor, 4 GB DDR4 non-ECC memory, two SATA drive bays, two M.2 NVMe cache slots and expansion to seven drive bays with the DX525.
Compact storage for backup, sharing and edge workloads
The Synology DS725neo+ is a compact two-bay desktop NAS designed to centralise files, backups and shared data while providing room to expand. It supports SATA HDDs and SSDs, two M.2 2280 NVMe SSDs for cache, and one DX525 expansion unit for a total of seven drive bays. Synology applications extend the system with private-cloud access, file synchronisation, data protection, collaboration and surveillance.
Key features and benefits
Compact two-bay design
A small desktop footprint makes the DS725neo+ suitable for home, small-business and edge locations where space is limited.
Expandable to seven bays
Start with up to 48 TB of raw storage across two bays, then add one DX525 for up to seven bays and 168 TB of total raw capacity when using 24 TB drives.
Built-in 2.5GbE
The hardware specification lists one 2.5GbE RJ-45 port alongside one 1GbE RJ-45 port for network connectivity.
Two M.2 NVMe cache slots
Two M.2 2280 NVMe SSD slots support compatible SSD cache configurations to improve storage responsiveness.
Private cloud and file sharing
Store, sync, access and share files across devices through mobile apps, desktop clients and a browser-based interface, with versioning available for file recovery.
Smart surveillance
Synology Surveillance Station provides centralised monitoring, playback and management, with the DS725neo+ positioned to manage up to 40 IP cameras.
Backup, synchronisation and collaboration workflows
Centralised backup and recovery
Consolidate backups for PCs, file servers, virtual machines, SaaS applications and Synology systems, with scheduled backup and restore options.
Immutable snapshots
Protect critical LUNs and shared folders with automated immutable snapshots backed by custom retention policies and offsite replication support.
Multi-site synchronisation
Use automatic one-way or two-way NAS-to-NAS synchronisation to keep files aligned across multiple locations.
Public cloud synchronisation
Keep data in sync with Backblaze B2, Dropbox, Google Drive and Microsoft OneDrive using configurable controls.

Back up and organise photos, videos and other visual assets, create albums and generate secure sharing links.
Central fleet management
Central Management System and Active Insight provide tools for managing and monitoring multiple Synology systems from central interfaces.
Who is the Synology DS725neo+ best for?
A strong choice for
- Home and family file storage
- Small-office shared storage and backup

Important information
Networking source conflict: the marketing copy says the DS725+/DS725neo+ features “two built-in 2.5GbE ports”, while the supplied hardware specification lists 1 × 1GbE and 1 × 2.5GbE. This description follows the hardware table for the key specification and FAQ sections.
SSDs are sold separately. Check compatible drive, SSD and memory requirements before purchase.
Synology only guarantees full functionality, reliability and performance for compatible drives.
The stated performance figures are based on Synology internal testing. Actual performance may be lower due to differences in server configuration, deployment and the number of active operations.
Noise testing was conducted with the Synology system fully installed with Synology SATA HDDs and in an idle state.
