The Sonnet Echo Express SEL is a streamlined Thunderbolt expansion system, built to integrate a single low-profile PCIe card into your Mac, Windows, or Linux setup. Perfect for mobile or compact workstations, it’s a reliable way to add pro-grade functionality — including video I/O, high-speed networking, or SSD storage — to modern workflows.

Housed in a rugged aluminium chassis, the Echo Express SEL delivers full PCIe 3.0 performance via a x8 slot (x4 electrical), and stays cool and quiet thanks to its temperature-controlled variable-speed fan. With dual Thunderbolt 3 ports, it supports daisy-chaining and supplies up to 15W of power to connected peripherals.

It's fully compatible with Apple silicon Macs, as well as current Windows and Linux systems, making it a smart and versatile choice for professional environments.

Technical Notes	While the Echo Express SEL features a 40Gbps Thunderbolt interface, some Windows computers equipped with Thunderbolt 3 use an x2 PCIe lane implementation of Thunderbolt 3 technology that limits PCIe performance to 20Gbps. Second Thunderbolt port supports USB 3.2 Gen 1 (5Gbps) or Gen 2 (10Gbps) devices when connected with proper cable or adapter (sold separately). Full performance requires the use of the included Thunderbolt cable or any Thunderbolt 5, 4, or 3 cable; not Thunderbolt 20Gbps cables. Look for the Thunderbolt icon and the number 5, 4, or 3 on the connector housings to identify 40Gbps or better Thunderbolt cables. ThunderLok compatible specifically with Sonnet 0.5- and 0.7-meter Thunderbolt cables.
