Synology DiskStation DS925+

Versatile 4-Bay Storage Solution with Expandable Capacity

The Synology DiskStation DS925+ is a capable 4-bay NAS solution designed to be the central data hub for homes and small businesses. It offers the flexibility to adapt to growing storage demands, supporting up to nine drives with an expansion unit, dual M.2 NVMe slots for high-speed SSD caching, and built-in 2.5GbE for fast, out-of-the-box networking. Powered by the award-winning Synology DiskStation Manager (DSM) operating system, the DS925+ is a flexible, all-in-one solution for modern data sharing, synchronization, backup, and surveillance needs.

The Synology “Plus” Series

The “Plus” series from Synology represents the ideal balance of performance, versatility, and scalability, targeting prosumers, enthusiasts, and small to medium-sized businesses. These models are equipped with more powerful processors and expandable memory compared to the entry-level J series, enabling them to handle more demanding tasks like running virtual machines, hosting business applications, and supporting a larger number of concurrent users. With features like M.2 NVMe SSD cache support and the ability to connect expansion units, the Plus series provides a clear growth path, ensuring your initial investment continues to deliver value as your data needs evolve.

What’s New: DS925+ vs. DS923+

The Synology DS925+ marks a significant update from its predecessor, the DS923+. The most notable change is the move to a newer generation AMD Ryzen V1500B quad-core processor, which provides enhanced processing power for applications and multitasking. Crucially, the DS925+ now comes standard with dual 2.5GbE LAN ports, a major upgrade from the 1GbE ports on the DS923+, offering more than double the networking speed right out of the box for faster file transfers and backups without needing an optional upgrade module.

Optimised for Synology Drives

For the best possible performance, stability, and longevity, it is highly recommended to populate your DS925+ with Synology-validated drives, such as the HAT5300 series enterprise HDDs or SAT5200 series SSDs. These drives are specifically engineered and rigorously tested to work seamlessly with Synology’s hardware and DSM operating system. This tight integration ensures that the drives and the NAS can communicate perfectly, unlocking peak performance and providing enhanced monitoring and maintenance features that are not available with third-party drives.

The Synology Drive Advantage

Choosing Synology drives over third-party options provides a more reliable and streamlined user experience. Synology drives undergo thousands of hours of stringent stress testing on the exact NAS models they are intended for, guaranteeing compatibility and resilience under heavy workloads. A key advantage is the ability to perform firmware updates directly through DSM, a feature not possible with other brands. This ensures your entire storage system, from the OS to the drive firmware, is always up-to-date and secure, providing long-term peace of mind and a single point of contact for support.
