Add Four Powerful 5Gb/s SuperSpeed USB 3.0 Ports –
Each with Its Own Dedicated Controller
Do you frequently need to hook up multiple USB 3.0 drives for fast backups and drive-to-drive duplication? If you are looking for the best possible performance, install the Allegro™ Pro USB 3.0 PCIe adapter in your Mac Pro® tower, Windows® PC, or Thunderbolt™ expansion system with a PCIe slot. This pro Sonnet card adds four SuperSpeed USB 3.0 ports to your computer, but unlike conventional adapter cards, each port has its own controller.
