Interface card Sonnet Allegro Pro USB 3.2 Gen 1

The Sonnet Allegro Pro USB 3.2 Gen 1 is an internal PCIe interface card that adds four SuperSpeed (10 Gbit/s) USB-A ports to desktop systems. Designed for installation in Mac Pro towers, Windows PCs, or Linux computers with available PCIe slots — or in Thunderbolt-to-PCIe expansion systems — it enables modern high-performance USB drives and bus-powered SSDs to operate at their intended speeds and power requirements.

Advantages

This PCIe card provides four USB 3.2 Gen 1 (also referred to as USB 3.1 Gen 1) ports that deliver up to 10 Gbit/s aggregate bandwidth, allowing single-device transfer rates far higher than legacy USB 3.0/3.1 Gen 1 host ports. Installing the Sonnet Allegro Pro removes the throughput and power limitations of older host controllers, supports fast SSD-based USB drives with transfers up to 750 MB/s when connected to compatible devices, and fits into standard PCIe slots for straightforward internal installation.

How to use

Power down your computer and install the Allegro Pro card into an available PCIe slot (or mount it in a Thunderbolt-to-PCIe enclosure). Secure the card, reconnect power, and boot the system. Install any required drivers supplied by the operating system or Sonnet if prompted. After driver installation, connect USB-A devices to the card’s ports; the system will recognize them as high-speed USB 3.2 Gen 1 devices and allow transfers at the card’s supported rates.

Recommendations

For maximum performance, connect SSD-based or high-performance USB drives directly to the Allegro Pro’s ports and ensure your operating system has the latest drivers. If using bus-powered drives, verify the card and system provide sufficient power, or use externally powered enclosures when needed. When installing in Thunderbolt expansion systems, use a Thunderbolt interface with adequate bandwidth to avoid bottlenecks.
