The Synology E10G30-T1 is a single-port 10GBASE-T add-in card designed to significantly increase the network bandwidth of your NAS. By providing 10GbE speeds, it allows you to move large files more quickly and reduces bottlenecks when multiple users access the server simultaneously. This card simplifies setup through plug-and-play installation and supports CPU offloading, which helps maintain system performance by reducing the processing load on the main CPU. It also utilizes load balancing technology to optimize data traffic. Thanks to auto-negotiation, the card remains backward compatible with slower network speeds, making it a versatile choice for those upgrading their infrastructure gradually.
