Professional-Grade USB Expansion
The Sonnet Allegro Pro is a seriously impressive USB expansion card. What makes this card special is its architecture: the four USB 3.2 ports are split across two independent channels, which means you can run multiple high-speed devices at the same time without them fighting for bandwidth. Copying data from one port group to the other is incredibly fast and consistent — it feels like having two separate USB controllers in one card. In real-world use, this makes a huge difference. I regularly connect multiple SSDs, card readers, and capture devices at once, and performance stays stable instead of collapsing the moment you plug in a second device. Transfers between devices on different channels are especially quick, which is exactly what you want in a professional workflow. Build quality is excellent, as you’d expect from Sonnet. It installs cleanly, is instantly recognized by the system, and just works without drivers or fiddling. No glitches, no disconnects, no weird behavior. If you need serious USB performance in a desktop or workstation, this card is on a completely different level from cheap multi-port USB cards. It’s built for real work, and it shows. Five stars.

Great value for the increase in performance
The card was easy to install. Performance measurements are well beyond my expectations. Brought new life into the Mac Tower for increasing data rates to/from my USB devices. I also installed a 3.0 hub that allows me to install multiple USB drives on the first port of the card. On the second port I connected a 3.1 RAID (4 drive system) from OWC which runs independently form the first port. This allows maximum speed from two independent ports on the card. Highly recommend the addition of this card for increasing the usefulness of portable USB drives and backup systems!
