Perfect but Synology exaggerates
Very fast delivery and parcel received in very good condition! Thanks LDLC!
Card installed without a problem (just need to find the right screwdriver to remove the cover), my switch is in 2.5 G but it goes faster than with the original 1 GB ports.
On the other hand, Synology is exaggerating, they could deliver this 10 G port as standard without having to spend more than 150€ to get good speed on a local network!
