Echo Express SE III

Connect Three PCIe Cards to any Computer with Thunderbolt 3 Ports

Sonnet’s Echo™ Express SE III is a compact desktop Thunderbolt™ 3 to PCIe Card Expansion System that enables you to connect three professional PCIe cards—including video capture, audio interface, SAS or SATA HBA, 16Gb or 8Gb Fibre Channel, 10 Gigabit Ethernet, and RAID controllers—at the same time to any computer with Thunderbolt 3 ports.

The Echo Express SE III features a 40Gbps Thunderbolt 3 interface, which offers double the PCIe bandwidth and connectivity of Thunderbolt 2, and yields up to 2750 MB/s of bandwidth, enabling it to support 4K video capture and processing cards at high frame rates, and 16Gb FC cards and dual-port 10GbE cards at full performance(1)(2). With the ability to handle multiple demanding, high performance PCIe cards, support for connecting two 4K displays @ 60Hz or one 5K display @ 60Hz(3), and support for a vast array of Thunderbolt(4) and USB(5) devices, Thunderbolt 3 is a leap forward in every way.
