Thunderbolt 5 doubles bandwidth over Thunderbolt 4, from 40Gbps to 80Gbps, giving creative professionals and power users faster data transfer and more flexible multi-display setups without sacrificing port variety.

- The Echo 21 upgrades all Thunderbolt ports to Thunderbolt 5, doubling bandwidth to 80Gbps.
- It retains the same design as the Echo 20 but adds an M.2 SSD slot, 10Gb Ethernet, and expanded USB and display support.
