Connect Three Full-height, Half-length+ PCIe Cards

Although Mac®, Windows®, and Linux® computers with Thunderbolt™ 4 or Thunderbolt 3 ports offer processing power to spare, for many users (such as pros in the creative fields) onboard processing power alone is not enough. The computers lack the PCIe expansion slots needed to install specialty cards that add video and audio inputs, transcode data, and connect to high-speed shared storage and networks. Sonnet’s Echo™ Express SE IIIe is a compact, desktop Thunderbolt to PCIe card expansion system that enables you to connect three professional PCIe cards to your computer at the same time, via a single Thunderbolt cable.
