Unleash Pro-Grade Connectivity: 8 Independent 10Gb/s USB-C Ports

For creative professionals, a workflow bottlenecked by slow connections or a lack of ports is a constant frustration. The Sonnet Allegro Pro USB-C 8-Port PCIe Card is the definitive solution, engineered to supercharge your Mac Pro®, Windows®, or Linux® workstation with the massive, high-performance connectivity that power users demand.

What sets the Allegro Pro apart is its superior architecture. Instead of sharing bandwidth across all ports, it features four independent 10Gb/s USB 3.2 controllers, dedicating one full controller to each pair of ports. This groundbreaking design means you can connect multiple high-performance SSDs, hubs, and docks and transfer files simultaneously, with each port delivering its maximum 10Gb/s speed without impacting the others. Move massive 4K video files, complex project assets, and entire backups at full speed, all at once.

Power and stability are critical in a professional setting. The Allegro Pro delivers a robust 7.5W of power to every port, enough for the most demanding bus-powered drives and peripherals. It achieves this by drawing all power directly from the PCIe slot—no messy auxiliary power cables are required. More importantly, its independent, per-port power regulation prevents the frustrating power glitches that can cause drives to disconnect during a critical render or data transfer, ensuring your devices stay connected and your workflow remains uninterrupted.

Designed for the rigors of daily professional use, the Allegro Pro includes essential safeguards. Each of the eight ports is protected by a resettable fuse, shielding your card and computer from damage from a faulty cable or peripheral. If a fuse ever trips, a simple computer restart is all that's needed. With full hot-swap support, you can connect and disconnect devices on the fly without ever needing to shut down. Upgrade your machine and unlock its true potential with the ultimate 8-port USB-C expansion card.
