6. Sonnet Thunderbolt 3 Upgrade Card - Thunderbolt Adapter
Upgrade instead of adapting
Why adapt when upgrading offers more? With the Thunderbolt 3 upgrade card installed you get:
Thunderbolt 3 bandwidth
The Thunderbolt 3 upgrade card provides increased 40Gbps bandwidth—with an adapter you are limited to Thunderbolt 2’s 20Gbps bandwidth.
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.

7. Sonnet ECHO II DV Desktop Two-Slot Full-LengthThunderbolt PCIe Card System
Connect two demanding DV I/O cards to computers with Thunderbolt 4 or Thunderbolt 3 ports. For creative professionals in the audio and video broadcasting industries, using the latest high-performance notebooks, compact desktops, and all-in-one computers requires multiple I/O ports. While these Mac, Windows, and Linux computers include high-performance Thunderbolt 4 or Thunderbolt 3 ports, they lack PCIe expansion slots to install specialty cards with dedicated bandwidth to each card.
Make your broadcast studio with the Echo II DV Desktop. Computers such as Mac Studio and other M series Mac computers feature powerful Thunderbolt/USB4 ports, each individually driven by their own dedicated Thunderbolt bus. To harness this dedicated power, Sonnet has a creative solution — the Echo II DV Desktop — a professional Thunderbolt to PCIe card expansion system that enables you to connect two (up to) full-length (12.28 inches long) PCIe cards at the same time, via two cables. The Echo II DV Module exploits your computer’s full potential, connecting two PCIe 3.0 card slots — each with its own Thunderbolt interface — for you to install two bandwidth-hungry DV I/O cards in one enclosure.
Note: For maximum performance with more than one bandwidth-hungry PCIe card, such as the DeckLink 8K, this product requires connection to two Thunderbolt ports on the computer.
When your computer has only one Thunderbolt port, you can still use the Echo II DV Desktop. Because each PCIe card slot is supported by its own Thunderbolt interface with two Thunderbolt ports, you can take advantage of Thunderbolt’s daisy-chaining feature. Simply connect one Thunderbolt interface to the other using one of the two supplied Thunderbolt cables, and use the other cable to connect to the computer.
