Sonnet Echo SE I Thunderbolt 5 Single-Slot Expansion Chassis for PCIe Cards

The Sonnet Echo Express SE I Thunderbolt 5 Expansion System is a desktop PCIe enclosure that connects a single full-height expansion card to your Thunderbolt 5 computer, delivering up to 80 Gb/s bandwidth for professional video capture, high-speed network interfaces, and storage controllers.
