Sonnet Echo III Silver Steel 1

The best portable, mini desktop and all-in-one computers feature powerful CPUs and include high-performance Thunderbolt™ ports to support peripherals. But they lack the PCIe expansion slots creative pros need to install specialty adapter cards that enable their workflows by adding video and audio inputs, transcoding data, and connecting to high-speed shared storage and networks. Sonnet has a Thunderbolt solution — the Echo™ III Rackmount — a professional Thunderbolt to PCIe card expansion system. Via a single cable, connect three (up to) full-length (12.28 inches long) PCIe cards at the same time to your Mac®, Windows®, or Linux® computer with Thunderbolt 4 or Thunderbolt 3 ports.
