Needed a reliable 3.1 USB upgrade card for my Mac Pro 5,1. Read many reviews that pointed me to the Sonnet card. The reviews were correct. Plug and play? no issues. Glad I chose the Sonnet. Now have a 3.0 and 3.1.

Works great with my Lacie Raid setup. Speeds are great. Just what I need to add some extra USB-C ports. Did not work with my Occulus Quest though. Only reason it gets 4 out of 5 stars.

Designed for maximum compatibility, this card is ideal for Mac Pro, Windows PC, or Linux computers with PCIe slots. It's also Thunderbolt compatible, making it a versatile choice for those with Thunderbolt-enabled devices.
Unlike ordinary USB-C cards, the Allegro USB-C 4-Port PCIe card features two 10Gbps USB 3.1 Gen 2 controllers and four USB-C ports, supporting data transfers at lightning-fast speeds. With its dual controllers, this card not only speeds up data transfers between connected drives but also enables your computer to load and off-load data more quickly.
This card is not just about speed; it's also about power. Each of its four ports provides 7.5W of power, supporting USB bus-powered hard drives and SSDs without the need for an additional AC power adapter. The Allegro card's intelligent power delivery and management system ensures optimal power regulation, preventing auto-disconnects of already-connected drives.
The Allegro USB-C 4-Port PCIe card also features resettable fuses on each port, protecting both the card and your computer in case of a cable or peripheral failure. Resetting a tripped fuse is as simple as restarting your computer.
Perfect for use in Sonnet's Thunderbolt 2 and Thunderbolt 3 to PCIe card expansion systems, this card adds four SuperSpeed+ USB-C ports to your computer, even without expansion card slots. It supports hot-pluggable and hot-swappable device connection with automatic device configuration, and works with all USB-IF compliant USB peripherals.
Experience the convenience of easy installation into any PCIe x4 (mechanical) or larger slot. Upgrade your tech setup with the Allegro USB-C 4-Port USB 3.1 Gen 2 PCIe Card, and enjoy faster, more efficient data transfers and power delivery.
