Sonnet Thunderbolt 3 Upgrade Card for Echo Express SE I Expansion System

Step Up to 40Gbps Thunderbolt 3
Sonnet designed Echo Express Thunderbolt 2-to-PCIe card expansion systems (and select Thunderbolt 2 adapters) to be easily upgraded to 40Gbps Thunderbolt 3. Simply replace the existing Thunderbolt interface board with the upgrade board and then your chassis will instantly support higher performance and connect to your Thunderbolt 3-equipped computer without needing an adapter.

Increased Bandwidth, Better Performance
With a Thunderbolt 3 interface card installed, your upgraded Echo Express Thunderbolt 2 system gains from 30% to 100% more bandwidth over the original system (see performance Tab for details). Installed in an upgraded system, PCIe cards with high bandwidth requirements, such as 16Gb Fibre Channel and 4K Video I/O cards supporting high frame rates, will be able to perform even better than before.

Easy to Install 40Gpbs Thunderbolt 3 Upgrade Card
Replaces existing 20Gbps Thunderbolt interface board in your Thunderbolt 2-to-PCIe card expansion system

Improved Performance with High-Bandwidth PCIe Cards
Your upgraded expansion system will provide from 30% to 100% more bandwidth for installed PCIe cards

Two Thunderbolt 3 (USB-C) 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

ThunderLok 3-Compatible
Thunderbolt connector retainer clip secures cable from accidental disconnections

Upgrade Instead of Adapting
Why adapt when upgrading offers more? With the Thunderbolt 3 upgrade card installed you get:

Increased Bandwidth
The Thunderbolt 3 upgrade card provides increased 40Gbps bandwidth-with an adapter you are limited to Thunderbolt 2's 20Gbps bandwidth.

Optimal Thunderbolt 3 Daisy Chaining
The upgrade card supports additional Thunderbolt 3 peripheral devices in the Thunderbolt chain with 40Gbps bandwidth. With an adapter all downstream devices in the Thunderbolt chain can only be Thunderbolt or Thunderbolt 2 devices.

Connect USB Devices
Sonnet's Thunderbolt 3 upgrade cards also include 10Gbps USB 3.1 Gen 2 support, meaning you can connect a USB device to the second port using the proper cable or adapter; they also provide full support for connecting two 4K displays at 60Hz or one 5K display at 60Hz.

ThunderLok 3-Compatible
Sonnet's Thunderbolt 3 upgrade cards support the ThunderLok 3 Thunderbolt connector retainer clip. The ThunderLok 3 (sold separately) secures the Thunderbolt cable (sold separately) to the chassis and is easy to install and use-just slide it over one end of the cable and then plug in the connector and secure it to the chassis by turning a thumbscrew. Because of its unique design, ThunderLok 3 remains on the cable so it won't get lost when not in use.
