From the manufacturer
Powerful performance for modern workflows
Powered by a quad-core AMD Ryzen V1500B processor and 8 GB of ECC memory (expandable to 32 GB), the DS1525+ delivers up to 1,181 MB/s read and 1,180 MB/s write throughput. With the optional 10GbE upgrade card, plus support for both M.2 NVMe and 2.5” SATA SSDs, external hard drives and third-party cloud services quickly become obsolete.
Optimized for every stage of your creative process
Automatic ingestion – Import new files directly from USB into an all-flash pool using SNV5400 or SNV3400 enterprise NVMe SSDs. Utilize the NAS to store high resolution images and videos and generate proxy files for faster edits in the tool of your choice.
Editing performance – Collaborate on projects stored on SAT5200 enterprise SATA SSDs; with 10GbE networking, multiple editors can work without bottlenecks.
Seamless archiving – Offload completed work to a high-capacity HDD pool on a DX525 expansion unit, automatically building a long-term archive of your portfolio.
Triple the expandability
Scale your storage to 15 drives with up to two DX525 expansion units. Synology’s on-the-fly volume expansion and hot-swappable bays allow you to grow without downtime, ensuring continuous availability for mission-critical work.
Better together: multi-unit advantages
Adding a second Synology NAS multiplies value by improving redundancy, enabling collaboration, and unlocking enterprise-grade flexibility:
- Two-way file synchronization between remote teams
- Off-site backup for disaster recovery
- Hybrid cloud expansion for scalable workloads
- Multi-site surveillance deployments with centralized management
- Quad-core AMD Ryzen CPU with ECC memory for stability
- Up to 32 GB ECC memory for demanding workloads
- Up to 1,181 MB/s read / 1,180 MB/s write throughput
- 2 x M.2 NVMe SSD slots for caching or dedicated storage pools
- Built-in tools for file sync, sharing, and collaboration
- Snapshot and backup protection against ransomware
- Network upgrade slot supporting optional 10GbE
Why choose the 25+ Series?
Unified, intuitive data management
Every 25 Plus series NAS runs the latest version of Synology DSM, delivering seamless file storage, sharing, device backup and multimedia management. Standard features include fast setup, system-wide search and remote access on all models, from compact 2-bay units to scalable 18-bay systems with raw capacities ranging from 40 TB to 360 TB.
Flexible management and expansion
Even compact models like the DS225+ support sizable volumes for home or office and can scale seamlessly into a hybrid cloud. Larger units such as the DS1825+ add ECC RAM, NVMe SSD caching and support for high-end upgrades, while all models include essentials like dual USB-A ports, hot-swappable drives and tool-less trays.
Improved networking across the lineup
Every 25 Plus series system includes at least one 2.5GbE port, providing faster transfers than previous generations. Five- and eight-bay models feature dual 2.5GbE, SMB3 Multichannel and PCIe slots for 10/25GbE adapters, eliminating gigabit bottlenecks across the range.
Full suite of apps and security at any size
From two-bay setups to fully scaled 18-bay systems, the 25 Plus series gives you full access to the DSM app library, including file syncing, surveillance, virtualization, cloud backup and media streaming. All models support backup, versioning, device management and multi-factor authentication to keep data secure at any scale.
