4-Bay Expandable Desktop NAS
Synology DS925neo+ Network Attached Storage
Consolidate and protect growing digital data with a four-bay Synology NAS featuring an AMD Ryzen V1500B processor, 4 GB DDR4 non-ECC memory, dual 2.5GbE networking, two M.2 NVMe slots and expansion to nine drive bays with the DX525.
Flexible storage for files, backup and collaboration
The Synology DS925neo+ is a four-bay desktop NAS designed to bring documents, photos, backups and other digital assets into one central system. It combines dual 2.5GbE networking with SATA storage, two M.2 NVMe slots and expansion through the DX525, while Synology applications support private-cloud access, file synchronisation, data protection, collaboration and surveillance.
Key features and benefits
Dual 2.5GbE networking
Two built-in 2.5GbE LAN ports provide high-speed network connectivity for shared storage, backups and file access.
Four bays with room to expand
Use four internal SATA bays for up to 96 TB of raw storage, then add a DX525 expansion unit to reach nine bays and up to 216 TB of raw capacity when using 24 TB drives.
Two M.2 NVMe slots
Two M.2 2280 NVMe slots can be used with compatible SSDs for cache or storage pool creation.
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.
Centralised backup and recovery
Consolidate backup tasks for PCs, file servers, virtual machines, SaaS applications and Synology systems, with options for scheduled backups and immutable snapshots.
Smart surveillance
Synology Surveillance Station provides centralised monitoring, playback and management, with the DS925neo+ positioned to manage up to 40 IP cameras.
Built for connected data workflows
Photo storage and organisation
Back up and organise photos, videos and other visual assets, create albums and generate secure sharing links for teammates and stakeholders.
Team collaboration
Synology productivity solutions support real-time document creation, editing and sharing, together with on-premises email and secure communication tools.
Multi-site synchronisation
Use one-way or two-way NAS-to-NAS synchronisation to keep files and folders aligned across homes, offices and branch locations.
Hybrid cloud workflows
Keep frequently used files locally available while placing less frequently accessed data in the cloud to reduce on-site storage requirements.
Public cloud synchronisation
Synchronise data with Backblaze B2, Dropbox, Google Drive and Microsoft OneDrive using configurable sync and bandwidth controls.
Central fleet management
Central Management System and Active Insight provide centralised tools for managing Synology servers and monitoring system activity across multiple deployments.
Who is the Synology DS925neo+ best for?
A strong choice for
- Home-office and small-business centralised storage
- Shared documents, photos and digital asset libraries
- Private-cloud file access and synchronisation
- Multi-device and multi-site backup workflows
- Teams using collaborative Synology applications
- Surveillance deployments requiring management of up to 40 IP cameras
Consider another model if you need
