Echo II DV Desktop Thunderbolt 5 Two-Slot Full Length PCIe Card Expansion System

Desktop 2-slot dual Thunderbolt 5 interface to PCIe card expansion system for pro DV I/O cards for Computers with Thunderbolt or USB4 Ports

Are you a creative pro using one of the hot new laptops or mini desktops with ultra-high-performance Thunderbolt™ 5 ports in your workflow? They offer tremendous onboard processing power, but don’t have the PCIe slots you need for connecting adapter cards to add specialized ports and processing capabilities critical to your workflow.

Sonnet Echo™ II DV T5 Desktop overcomes the no-slots limitation. This pro Thunderbolt 5 to PCIe card expansion system enables you to connect two full-length, single-width PCIe cards to your computer, each to a separate Thunderbolt port for maximum bandwidth to each card — it’s the ultimate solution for connecting cards with high bandwidth requirements.

Computer System Requirements

To support maximum performance when using two bandwidth-hungry PCIe cards, Echo II DV T5 Rackmount requires the following:

Two connections between the Echo II DV T5 module and the host computer(s) with two Thunderbolt 5 ports with independent PCIe bandwidth.
