The DS1825+ comes equipped with two integrated 2.5GbE ports, providing robust network connectivity right out of the box. Additionally, the system features two M.2 slots, allowing users to create an all-flash storage pool for high-performance applications or use them as an SSD cache to boost read/write speeds.
The DS1825+ enhances connectivity by incorporating a PCIe 3.0 slot to support high-speed 10GBASE-T or 10/25Gb SFP+/SFP28 adapter cards, ensuring optimal data transfer rates for demanding applications.
In performance tests, the DS1825+ achieves a sequential SMB performance with SSD of up to 2,239 MB/s read and 1,573 MB/s write.
The system is designed 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 needs grow, providing a future-proof solution for long-term storage requirements. The DS1825+ offers up to 360 TB of raw storage when fully expanded.
The DS1825+ is designed as a complete system to deliver consistent performance and reliability with compatible hard drives. It follows a carefully selected disk compatibility framework, backed by over 7,000 hours of rigorous testing. To ensure optimal integration and long-term reliability, DSM in the DS1825+ requires compatible hard drives for installation.
