Product information

Description

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.

Suitable for

Connecting multiple high-speed external SSDs and USB drives
Adding modern USB-A SuperSpeed ports to older desktops
Use in Mac Pro, Windows, or Linux systems with PCIe or Thunderbolt-to-PCIe expansion
Workflows requiring faster file transfers, such as video editing or large data backups

Key specifications

Output interface: 4 × USB 3.2 Gen 1 (USB-A)
Host interface: PCIe (internal card)
Bandwidth: up to 10 Gbit/s (SuperSpeed)
Internal: Yes
EAN: 0732311012631

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.

Usage 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.
