As a strong advocate of 10Gbe networking on XPenology, I am happy to finally see an affordable, passively-cooled switch on the market (even though many folks don't even need a switch - a direct-connected multi-port NIC will often suffice).   To use it, you'll have to familiarize yourself with DACs and/or optical SFP's but this is a major step forward for the price.   https://www.servethehome.com/mikrotik-crs305-1g-4sin-review-4-port-must-have-10gbe-switch/
