It does not have an internal optical drive.

Connectivity includes 3-stream AirPort Extreme (802.11a/b/g/n), Bluetooth 4.0, two USB 3.0 ports, two "Thunderbolt" ports, an HDMI port, an audio in/out port, and an SDXC card slot. It does not have Gigabit Ethernet or Firewire "800," although adapters are available at extra cost.
