Built with a PCIe 2.0 x4 interface, this card features dual USB 3.2 Gen 2 controllers, each of which drives two of the USB ports. Data transfer speeds are supported up to 800 MB/s when one drive is connected, and up to 600 MB/s when two drives are connected. With all four ports in use, each port supports speeds up to 300 MB/s. Designed to be hot-pluggable and hot-swappable, this card may also be used in Thunderbolt 2 or Thunderbolt 3-to-PCIe card-expansion systems, including Sonnet's Echo Express and xMac.
