The AirPort Extreme Base Station has faster data throughput and includes the new 802.11ac standard, and you can attach an external hard drive to it for wireless Network Attached Storage (NAS). AirPort Express still lacks the newer 802.11ac network as it hasn’t been updated by Apple for some years now. The unit features the 802.11n dual band antenna. It’s a small device, with the same footprint as an Apple TV, and it creates a Wi-Fi network.

If you have more than one AirPort Express connected to speakers, you can play your music from iTunes on all of your speakers at the same time.

The AirPort Express was originally introduced by Apple as a way of streaming your music from iTunes on your Mac to a Hi-Fi (initially this ability was referred to as AirTunes, then AirPlay).
