Sonnet Allegro Pro USB 3.2 PCIe Card

This Sonnet Allegro Pro add-in card installs into a PCI Express slot to provide additional high-speed connectivity. It equips a Mac Pro, Windows PC or Thunderbolt to PCIe expansion system with four SuperSpeed 10Gbps USB-A ports. The board uses dual USB 3.2 Gen 2 controllers to move data at up to twice the rate of earlier USB 3.0 and 3.1 Gen 1 links.

Suited for storage and peripheral expansion

Creators and professionals who need to connect multiple bus-powered SSDs, SSD RAID arrays or hard drives will benefit from 7.5W of regulated power on every port. Independent power regulation prevents cross-coupled glitches and resettable fuses protect both the card and host. Buyers who require internal headers, USB-C connectors or a different port count should consider other options.

Dual USB 3.2 Gen 2 controllers

The two onboard controllers deliver up to 10Gbps bandwidth per port for fast transfers between attached drives. This specification determines whether the card matches the throughput needs of high-performance external storage workflows. Compatibility spans Mac, Windows 11 and Linux platforms with driver support.

Questions about this item

Does my computer need a free PCIe slot to install the Sonnet Allegro Pro card?

Yes, the card plugs into an available PCI Express slot inside a Mac Pro, Windows PC or Thunderbolt to PCIe expansion system.

Will my existing USB 3.0 drives still work when connected to the 10Gbps USB-A ports?

They will work at their native 5Gbps speed; the card is backward compatible with USB 3.0 and 3.1 Gen 1 devices.

How can I confirm each port is delivering the full 7.5W of bus power after installation?

Connect a bus-powered SSD or RAID; if it mounts and transfers without disconnects, the independent power regulation and resettable fuses are functioning correctly.
