Sonnet Thunderbolt 3 Upgrade Card for Echo Express SE II

The Thunderbolt 3 Upgrade Card from Sonnet upgrades your Thunderbolt 2 system to 40 Gb/s Thunderbolt 3. By replacing the existing Thunderbolt interface board on your Echo Express SE II with this upgrade board, your chassis will instantly support higher performance, and connect to your Thunderbolt 3-equipped computer without needing an adapter.
With the Thunderbolt 3 interface card installed, your upgraded Echo Express Thunderbolt 2 system gains from 30 to 100% more bandwidth over the original system. Installed in an upgraded system, PCIe cards with high bandwidth requirements, such as 16 Gb Fiber Channel and 4K Video I/O cards supporting high frame rates, will be able to perform better than before.

Replaces existing 20 Gb/s Thunderbolt interface board
Easy to install
Two Thunderbolt 3 ports, one port reserved for connection to the computer; second port supports daisy-chaining of up to five additional Thunderbolt devices, attaching a single USB peripheral device, or connecting up to two 4K displays or one 5K display
