Allegro USB-C 4-port PCIe Card
2X THE PERFORMANCE OF USB 3.0 AND USB 3.1 GEN 1 CONNECTIONS

Equipped with SSDs the fastest 3.1 Gen 2 USB drives you can buy today are capable of 800 MB/s data transfers—many are bus-powered too. But 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. Break through the bottleneck—install Sonnet’s Allegro™ USB-C 4-Port PCIe card in your Mac Pro? tower Windows? PC or Linux(1) computer with PCIe slots; or Thunderbolt™ to PCIe card expansion system to support your fast USB drives at maximum performance.
