Sonnet Echo III Black Aluminium 1

For creative pros using the latest portable, mini desktop and all-in-one computers in their workflows, onboard processing power alone is not enough to get the job done. While these Mac®, Windows®, and Linux® computers include high-performance Thunderbolt™ 4 or Thunderbolt 3 ports to support peripherals, what they lack is PCIe expansion slots to install specialty cards that add needed video and audio inputs, transcode data, and connect to high-speed shared storage and networks. Sonnet has a solution — the Echo™ III Desktop — a professional Thunderbolt to PCIe card expansion system that enables you to connect three (up to) full-length (12.28 inches long) PCIe cards at the same time, via a single cable.

Echo III Desktop
Echo III Desktop supports every Thunderbolt compatible, non-GPU PCIe 4.0, 3.0, 2.0, and 1.1 card available including video capture and transcoding; audio DSP; 6Gb or 12Gb SAS or SATA host bus adapter; 10Gb or 25Gb Ethernet; SSD storage; and other specialty types to your system.
