Allegro USB3C-4PM-E, 4 x USB-C to PCI Express 2.0 x4 Add-On Card
Powerful USB 3.2 Gen 2 Performance: Add Four USB-C 10Gbps Ports to Computers and Thunderbolt Expansion Systems with PCIe Slots
Equipped with SSDs, the fastest USB drives you can buy today are capable of 800 MB/s data transfers, and many are bus-powered. Most desktop computers (even new models) include generations-old USB interfaces that will throttle that performance and may not offer adequate power to allow bus-powered drives to operate. Install Sonnet’s Allegro USB-C 4-Port PCIe card into a PCIe slot of your Mac Pro®, Windows®, or Linux® computer, or Thunderbolt Expansion System, and support fast USB drives at maximum performance.
