Sonnet Echo Express SE-IIIe TB3 PCIe, Desktop, 3 Slots

Echo Express SE IIIe
3-slot Thunderbolt 3 desktop expansion system for PCIe cards

Pro Performance. Compact Design.

Connect Three Full-height, Half-length+ PCIe Cards
Although Mac®, Windows®, and Linux® computers with Thunderbolt™ ports
offer processing power to spare, for many users (such as pros in creative fields)
onboard processing power alone is not enough.
These computers lack the PCIe expansion slots needed to install specialty cards
that add video and audio inputs, transcode data, and connect to high-speed
shared storage and networks.

Sonnet’s Echo™ Express SE IIIe is a compact Thunderbolt Desktop Expansion System,
enabling you to connect three professional PCIe cards to your computer simultaneously
via a single Thunderbolt cable.

Supports M series Macs and Intel Macs with Thunderbolt 3 ports.
