Echo Express SE IIIe

3-slot Thunderbolt 3 desktop expansion system for PCIe cards

Connect Three Full-height, Half-length+ PCIe Cards to Computers with Thunderbolt 3 Ports

Although thin Mac®, Windows®, and Linux® computers with 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. Sonnet’s Echo™ Express SE IIIe is a compact, desktop Thunderbolt™ 3 to PCIe card expansion system that enables you to connect three professional PCIe cards at the same time to any computer with Thunderbolt 3 ports.

This compact desktop expansion system supports three professional PCIe cards (video capture; audio DSP; 6Gb or 12Gb SAS or SATA host bus adapter; 10Gb, 25Gb, or40Gb Ethernet; or RAID controller; etc.) and connects them to your computer through a single Thunderbolt 3 cable.
