By employing four host controller chipsets, each port operates on a separate independent transmission channel.

When multiple devices are connected, traditional single bus USB 3.0 cards share your maximum bandwidth between all ports.

This independent port architecture improves USB 3.0 performance by transferring data on four individual channels to your computer, giving you faster file transfers. The PEXUSB3S44V 4-Port PCI Express USB 3.0 Card lets you add four, dedicated 5 Gbps USB 3.0 ports to your PCIe x4-enabled PC.
