Hi all, What is the cheapest way to connect both gigabit ethernet and HDD on full speed to MacBook Air 13" mid-2011? Its USB ports are 2.0 (480 Mbps half-duplex) so their performance is not enough for any of the two (1000 Mbps full duplex and ~220 MBps peak full duplex needed respectively). It has only one Thunderbolt 1 port. There are Thunderbolt to Gigabit Ethernet + USB 3.0 or eSATA adapters but the cheapest I found costs ~90 USD. Are there cheaper ones or is this the lowest possible for Thunderbolt? Thank you for the help!
