Product information

Description

The Sonnet Allegro internal USB interface card adapter adds USB 3.2 Gen 1 (3.1 Gen 1) connectivity to a desktop system via a PCIe host interface. It provides multiple SuperSpeed+ USB-C ports with an indicated aggregate bandwidth of 20 Gbit/s, intended to enable high-speed connections for external drives, audio interfaces and other USB peripherals. The card is designed for workstation and content-creation environments where faster USB performance and sufficient port power are required than older onboard USB implementations typically provide.

Advantages

The Allegro card supplies multiple 10 Gbps-capable USB-C connections through a PCIe interface, allowing compatible external storage and bus-powered devices to operate at higher sustained transfer rates than legacy USB 3.0 ports. The adapter is compatible with standard desktop PCIe slots and offers per-port power delivery sufficient for many bus-powered USB-C devices. Its design targets improved throughput and responsiveness for workflows that depend on fast external storage, backup devices and professional audio peripherals.

Suitable for

  • Connecting high-performance external SSDs and NVMe enclosures that use USB-C.
  • Providing additional USB-C ports for audio interfaces, capture devices and peripherals.
  • Upgrading older desktops or workstation systems to faster USB connections for content creation and backup.
  • Systems that require multiple bus-powered USB-C devices with per-port power delivery.

Key specifications

  • Interface type: PCIe host card providing internal USB 3.2 Gen 1 (3.1 Gen 1) output.
  • Port type: USB-C SuperSpeed+ connections (10 Gbps per port capability).
  • Aggregate bandwidth: stated total of 20 Gbit/s for the card.
  • Power delivery: per-port power sufficient for many bus-powered devices (7.5 W per port stated by manufacturer).
  • Compatibility: designed for installation in compatible desktop PCIe slots and expansion systems.

How to use

Install the Allegro PCIe card into an available PCIe slot in a compatible desktop or expansion chassis following standard static-free assembly procedures and the system manufacturer’s guidelines. After securing the card and reconnecting power, boot the host system and install any required drivers or software provided by the system or Sonnet to enable the USB controller. Once the host recognizes the card, connect USB-C peripherals to the available ports. For bus-powered devices, confirm that the device operates correctly and that power requirements are met.

Usage recommendations

Use high-quality USB-C cables rated for SuperSpeed+ (10 Gbps) to achieve optimal transfer rates, and ensure the host system’s PCIe slot and platform drivers support the card’s bandwidth. For best results with external SSDs and other high-throughput devices, connect directly to a port on the card rather than through hubs that may limit performance.
