40Gbps Thunderbolt 3 — The USB C That Does It All The Echo Express III-D - Thunderbolt 3 Edition includes two Thunderbolt 3 (USB-C) ports; the first is used for connection to your computer, while the second supports daisy chaining of up to five additional Thunderbolt peripheral devices to a single port on your computer. The III-D includes 10Gbps USB 3.1 Gen 2 support, meaning you can connect a USB device to the second port using the proper cable or adapter. The III-D also provides full support for connecting two 4K displays @ 60Hz or one 5K display @ 60Hz(3). For connected devices requiring extra power, 15 watts is provided to connected bus-powered devices. All-Around Smart Design The Echo Express III-D - Thunderbolt 3 Edition is wrapped in a rugged, yet lightweight aluminum outer shell, resulting in a system light enough to carry without weighing you down, yet sturdy enough to securely protect the installed PCIe cards. Its two large, slow-spinning fans, enhanced with computer-modeled airflow management, ensure that even hot-running cards remain reliably cool without the need to install an extra PCIe blower card that would prevent the use of one of the three slots. Because the fans automatically speed up and slow down as needed, you don’t have to guess which speed setting to select, and there’s no need for tools to change settings. There is no power switch on the chassis, nor is one needed, because the III-D automatically powers on and off with your computer. Every Thunderbolt 3 and MacOS Compatible PCIe Card Supported The Echo Express III-D - Thunderbolt 3 Edition supports three single-width, full-length PCIe cards, or one double-width, full-length card plus one single-width card, enabling it to support every Thunderbolt 3- and macOS-compatible PCIe 1.1, PCIe 2.0, and PCIe 3.0 card available. Thunderbolt 3 (40Gbps) Cable Included To connect the Echo Express III-D - Thunderbolt 3 Edition to your computer, Sonnet includes a 1.0-meter Thunderbolt 3 (40Gbps) cable.
