The Thunderbolt 3 Connection
This compact desktop expansion system supports three professional PCIe cards (video capture; audio DSP; 6Gb or 12Gb SAS or SATA host bus adapter; 10Gb, 25Gb, or40Gb Ethernet; or RAID controller; etc.) and connects them to your computer through a single Thunderbolt 3 cable.
Although thin Mac, Windows, and Linux computers with Thunderbolt 3 ports offer processing power to spare, for many users (such as pros in the creative fields) onboard processing power alone is not enough. Echo Express SE IIIe is a compact, desktop Thunderbolt 3 to PCIe card expansion system that enables you to connect three professional PCIe cards at the same time to any computer with Thunderbolt 3 ports.
The Echo Express SE IIIe is designed to be ultra-quiet so that it can be comfortably used in noise-sensitive environments. Its enclosure is ventilated front and back to facilitate airflow over the cards bya large, quiet, temperature-controlled fan to efficiently cool the system. The fan automatically speeds up and slows down smoothly as needed - there's no guesswork in deciding which fan speed to select.
