The Thunderbolt 5 Upgrade Kit from Sonnet upgrades your Thunderbolt 3 system to 80 Gb/s Thunderbolt 5. By replacing the existing Thunderbolt interface board on your Echo Express SE I, SE II, or SE IIIe with this upgrade board, your chassis will instantly support higher performance and connect to your Thunderbolt 5-equipped computer without needing an adapter.
With the Thunderbolt 5 interface card installed, your upgraded Echo Express Thunderbolt 3 system increases bandwidth over the original system to up to 6800 Mb/s. Installed in an upgraded system, PCIe cards with high bandwidth requirements, such as 8K Video I/O cards supporting high frame rates, will be able to perform better than before. The dual Thunderbolt 5 ports provides up to 15W for bus-powered devices and a ThunderLok-A connector lock helps to prevent accidental disconnects.
