The all-new AirPort® Time Capsule® works with OS X® to automatically and wirelessly back up everything on your Mac® to its 2TB or 3TB hard drive.1 And it doubles as a full-featured Wi-Fi base station with next-generation 802.11ac technology.2
1 1TB = 1 trillion bytes; actual formatted capacity less. 2 AirPort Time Capsule is based on an IEEE 802.11ac draft specification. Performance based on comparison with Apple's 802.11n products. 3 Testing conducted by Apple in May 2013 using preproduction AirPort Time Capsule 802.11ac 2TB base stations. Performance may vary due to network configuration, distance, wireless interference, and other factors. Tests are conducted using specific devices and reflect the approximate wireless Time Machine backup performance of AirPort Time Capsule. TM and © 2017 Apple Inc. All rights reserved.
