Adds USB 3.2 Gen 1 Connectivity—Adds four USB-A 5Gbps ports to your Mac Pro®, Windows PC®, or Linux® computer with PCIe slots; or Thunderbolt™ to PCIe card expansion system. Speedy Performance—Transfers data up to 10x faster than over USB 2.0 connections. Super-Powered Ports—Supports USB 3.0 bus-powered hard drives, SSDs, DVDs & Blu-ray devices with up to 2.0A per port.

When it comes to supporting the fastest USB drives available, your computer’s USB 3.0 ports are perfectly adequate…for connecting peripherals that don’t depend on the ultimate USB 3.2 speeds. However, common USB 3.0 ports can be underachievers—at 5Gbps, they can’t support the maximum performance from many storage devices, and may not provide enough power to enable them to operate.

The Allegro™ USB-C PCIe⁽¹⁾ card supports data transfers at up to twice as fast as USB 3.0, and can also deliver 15W of power per port to USB-C bus-powered devices (three times the 4.5W specified in the USB 3.0 spec). Don’t settle for mediocre performance or insufficient power for the fastest SSDs—install an Allegro USB-C card to instantly add two Gen 2 USB 3.2 ports to your system and take full advantage of today’s SSD performance.
