Synology DiskStation DS925+ 4 Bay Desktop NAS Enclosure with NVMe M.2 Support

4-Bay Flexibility, on Your Desk

The Synology DiskStation DS925+ is a 4-bay desktop NAS built to deliver serious capability in a streamlined form factor. Supporting 3.5" and 2.5" SATA drives, as well as M.2 2280 NVMe SSDs, it provides versatile storage options that fit into virtually any environment—home office, studio, or business setup. From managing growing media collections to supporting daily backup routines or live project storage, the DS925+ adapts effortlessly to evolving data demands with the performance to keep pace.

Power Through Workloads

At the core of the DS925+ is a 4-core AMD Ryzen V1500B processor, clocked at 2.2 GHz and backed by 4 GB of ECC DDR4 memory, upgradeable to 32 GB. Built to handle everything from everyday file access to resource-heavy tasks like surveillance recording and VM archiving, the DS925+ offers balanced, dependable throughput. With dual 2.5GbE ports and high sustained read/write speeds, it widens out bottlenecks and keeps workflows running smoothly—even under pressure. Two built-in M.2 NVMe slots allow you to deploy high-speed SSD cache or dedicate them to storage pools, unlocking faster IOPS performance for high-demand workflows without occupying any of the main drive bays.

Seamless Storage and Sharing

With support for Btrfs and ext4 file systems, the DS925+ is more than just storage—it’s a robust platform for file collaboration, access control, and long-term reliability. Built-in tools make it easy to sync files across platforms and devices, with desktop, mobile, and browser-based access. Versioning support helps teams recover from accidental deletions or malware with minimal disruption.

Excellent RAID Compatability

The DS925+ offers flexible storage options to suit different needs. You can choose from several RAID types, including Synology Hybrid RAID, Basic, JBOD, and standard setups like RAID 0, 1, 5, 6, and 10 – ideal for balancing performance, capacity, and data protection. With the standard 4 GB of memory, you can create volumes up to 108 TB in size. If you upgrade the memory to 32 GB, this increases to a maximum of 200 TB. The system supports up to 32 volumes in total, and M.2 NVMe SSD slots allow for faster performance through caching or additional storage pools. It’s designed to grow with your data, with support for hot spare drives and easy expansion using larger hard drives over time.

A Smarter Private Cloud

The DS925+ allows you to create your own private cloud, streamlining data access across devices and locations. File syncing, sharing, and collaboration are unified under the Synology Drive suite, ensuring your team works from a consistent, secure source no matter where they’re located. Features like granular file rollback, sharing permissions, and mobile sync give users the freedom to work on their terms—while IT retains full control.

Reliable Backup and Data Protection

With built-in backup tools for endpoints, servers, virtual machines, and even cloud services like Microsoft 365 and Google Workspace, the DS925+ consolidates all your data protection into a single platform. Set up automated, centralized backup plans and use immutable snapshots to lock down critical data from tampering or ransomware. Recovery is fast and flexible, whether you need to restore a single file or an entire system.

Business-Ready Surveillance Station

The DS925+ supports Synology’s Surveillance Station, making it easy to manage and monitor up to 40 IP cameras. With intuitive controls, live view, remote access, and playback features, it transforms the NAS into a capable and secure NVR solution. Support for dual-recording and a wide range of camera models gives businesses peace of mind without investing in separate hardware.

Quiet, Cool, and Efficient

Despite its processing power, the DS925+ remains remarkably quiet at just 20.5 dB(A) in operation. Twin 92mm fans with selectable full-speed, cool, or quiet modes keep temperatures down even under heavy use. A 100W power supply ensures consistent performance while maintaining excellent power efficiency, drawing just 12.33 watts during HDD hibernation and under 38 watts during active use.

Synology Central Management System™

Managing one NAS is easy—managing many doesn’t have to be hard. The DS925+ supports Synology Central Management System for streamlined fleet oversight, policy enforcement, batch updates, and device monitoring. Cloud-powered Active Insight provides real-time diagnostics and status tracking for larger deployments.
