The Sonnet Allegro USB 3.0 4-Port PCIe Card is part number USB3-4PM-E, currently described by Sonnet as the Allegro Type-A USB 3.2 Gen 1 4-Port PCIe Card.
It provides four external USB-A ports from a single PCIe slot and is intended for adding dependable USB connectivity to workstations, servers and compatible Thunderbolt-to-PCIe expansion systems.
Four external USB Type-A ports support USB 3.2 Gen 1 operation at up to 5Gbps and maintain compatibility with older USB 3.x, USB 2.0 and USB 1.1 devices.
The card uses the Fresco Logic FL1100EX USB host controller, a well-established four-port controller used across Sonnet's professional USB expansion products.
The Allegro card uses a PCI Express 2.0 x1 host interface, allowing installation in a wide range of systems without consuming a larger-lane PCIe slot.
Sonnet specifies support for bus-powered hard drives, SSDs, DVD drives and Blu-ray devices, with up to 2A available for attached peripherals across supported operating conditions.
USB Attached SCSI Protocol is supported on compatible operating systems for efficient storage transfers, and the ports support hot-pluggable and hot-swappable USB device connection.
Sonnet continues to list USB3-4PM-E as a current-stock product and maintains an updated Quick Start Guide and support resources for the card.
