LEARNSynology Server Expansion Cards are proprietary PCIe-based interface modules that extend the connectivity and performance of Synology NAS systems by adding SAS, eSATA, or M.2 NVMe ports.
Most RackStation and certain high-end DiskStation models support Synology expansion cards; consult the Synology Compatibility List to verify compatibility with your specific NAS series and firmware version.
Power down your Synology NAS, open the chassis, insert the expansion card into an available PCIe slot, secure it with a screw, then close the case and reboot to enable the new interfaces.
By adding high-speed SAS, eSATA, or M.2 NVMe ports, Synology Expansion Cards can increase throughput by up to 12 Gbps per port and lower latency for demanding storage workloads.
