Synology Expands DiskStation Lineup with DS1825+ and DS1525+

Synology today announced the launch of two new DiskStation models, the DS1825+ and DS1525+, designed to provide small and medium businesses and professional users with compact, high-performance storage solutions.

"These two models offers a powerful foundation for data management and collaboration." said Owen Liao, Product Manager at Synology. "With evolving needs for data management, they are perfectly designed to deliver business-grade performance, scalability, reliability."

Provide Superb Performance and Scalability

To ensure optimal performance for demanding applications, the DS1525+ and DS1825+ come equipped with dual 2.5GbE ports. The DS1525+ can be easily upgraded to 10GbE via the E10G22-T1-Mini module, while the DS1825+ features a PCIe 3.0 slot that supports 10GBASE-T or 10/25GbE SFP+/SFP28 network cards. Both systems features two M.2 slots, allowing users to create an all-flash cache or storage pool for high-performance workloads. In performance testing, the DS1825+ delivered SMB sequential throughput of up to 2,239 MB/s read and 1,573 MB/s write using SSDs, while the DS1525+ achieved up to 1,181 MB/s read and 1,180 MB/s write.

Both systems are engineered for scalability, supporting capacity expansion with the addition of up to two 5-bay DX525 expansion units. This allows businesses to easily increase their storage capacity as their data requirements grow, providing a future-proof solution for long-term storage needs. The DS1525+ provides up to 300 TB of raw storage, and the DS1825+ provides up to 360 TB of raw storage1 when fully expanded with 18 and 15 drives respectively.

The DS1525+ and DS1825+ are designed as a full-featured system to deliver consistent performance and reliability with compatible hard drives. It follows a carefully curated drive compatibility framework, backed by over 7,000 hours of rigorous testing. To ensure optimal integration and long-term dependability, DSM on the DS1525+ and DS1825+ requires compatible hard drives2 for installation.
