When it comes to supporting the fastest USB drives available, your computer's USB 3.0 ports are perfect... for connecting peripherals that don't rely on ultimate USB 3.2 speeds. However, common USB 3.0 ports can underperform: at 5 Gbps, they cannot support the maximum performance of many storage devices and may not provide enough power to run them. With Sonnet's Allegro USB-C PCIe card installed in a PCIe slot of a Mac Pro®, Windows® or Linux® computer or Thunderbolt expansion system, you can upgrade to the benefits of SuperSpeed USB-C!
