Synology DiskStation DS925+ 4-Bay NAS with Dual 2.5GbE, M.2 NVMe Slots and Expandable Storage...Limited 3-Year Manufacturer Warranty
Overview
The Synology DiskStation DS925+ is a powerful and scalable 4-bay network-attached storage solution designed for businesses, creative professionals, advanced home users, branch offices, and retail environments.
Powered by a 2.2 GHz AMD Ryzen V1500B quad-core processor and equipped with 4GB of ECC DDR4 memory, expandable up to 32GB, the DS925+ delivers responsive performance for centralised file storage, multi-device backup, private cloud services, team collaboration, virtualisation workloads, and video surveillance.
Its four SATA drive bays support compatible 2.5-inch SSDs and 3.5-inch hard drives, while two integrated M.2 NVMe slots can be used for SSD caching or the creation of high-speed storage pools. Dual 2.5GbE network ports provide fast data transfers together with Link Aggregation, load balancing, and failover support.
The DS925+ can achieve sequential performance of up to 522 MB/s read and 565 MB/s write. Storage can be expanded from four to nine drives using the optional Synology DX525 expansion unit, providing up to 216TB of raw capacity when configured with supported 24TB drives.
Key Features:
Powerful AMD Ryzen Processing
The AMD Ryzen V1500B quad-core processor provides the processing power required for demanding storage, backup, file-sharing, and business applications. Combined with ECC memory, it helps maintain data integrity and reliable operation in professional environments.
Fast Dual 2.5GbE Networking
Two integrated 2.5GbE Ethernet ports deliver significantly faster network performance than standard Gigabit Ethernet. They also support Link Aggregation for increased bandwidth and failover for improved network availability.
Flexible Four-Bay Storage
The DS925+ accommodates up to four compatible 2.5-inch SATA SSDs or 3.5-inch SATA hard drives. Supported RAID configurations allow users to prioritise storage capacity, performance, redundancy, or a balance between all three.
Dual M.2 NVMe Slots
Two built-in M.2 2280 NVMe slots can be used for SSD caching or compatible high-speed storage pools without occupying the four main drive bays.
Expandable to Nine Drives
Businesses with growing storage requirements can connect the optional Synology DX525 expansion enclosure through the dedicated USB-C expansion port, increasing the system from four to nine drive bays.
Synology DiskStation Manager
Synology DSM provides an intuitive browser-based operating system for managing users, storage pools, permissions, backups, applications, and security settings.
Applications such as Synology Drive, Active Backup Suite, Hyper Backup, Snapshot Replication, Synology Photos, Synology Office, and Surveillance Station transform the DS925+ into a versatile private cloud and data-management platform.
Complete Data Protection
The DS925+ supports centralised backup of Windows and Linux computers, virtual machines, other NAS systems, and selected cloud applications. Snapshot Replication provides rapid point-in-time protection, while Hyper Backup supports versioning, compression, deduplication, and backup to multiple destinations.
Private Video Surveillance
Synology Surveillance Station transforms the DS925+ into a private network video recorder. The platform supports ONVIF-compatible cameras, remote monitoring, event-based actions, mobile access, and local recording without requiring recordings to be stored on a third-party public cloud.
Synology specifies support for managing up to 40 IP cameras, subject to camera resolution, recording settings, and system configuration.
Enhanced Security
Adaptive Multi-Factor Authentication, user delegation, encrypted connections, account protection, firewall controls, and Active Insight monitoring help protect business data and administrative access.
Compatible Storage Notice
Hard drives and SSDs are not included. Synology guarantees full functionality, reliability, and performance only when supported drives are used. The Synology compatibility list should therefore be checked before selecting HDDs or SSDs for the DS925+.
