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. This independent port architecture improves USB 3.0 performance by transferring data on four individual channels to your computer, giving you faster file transfers. When multiple devices are connected, traditional single bus USB 3.0 cards share your maximum bandwidth between all ports. By employing four host controller chipsets, each port operates on a separate independent transmission channel. Dedicating up to 5 Gbps to each USB port reduces performance bottlenecks, and effectively quadruples your total available to bandwidth to 20 Gbps. Enhanced with UASP support (USB Attached SCSI Protocol), this USB 3.0 controller performs up to 70% faster than conventional USB 3.0 when paired with a UASP supported enclosure . Using a more efficient protocol than the traditional USB BOT (Bulk-Only Transport), UASP technology optimizes transfers by allowing multiple commands to be processed simultaneously, significantly increasing transfer speeds for less wait time on data transfers. For high-power USB devices, this PCIe USB 3.0 card includes a power connector to connect to your system power supply and deliver up to 900 mA of power per port to USB 3.0 bus-powered devices (500 mA for USB 2.0). The controller card is compliant with USB 3.0 standards while offering backward compatibility with existing USB 2.0 / 1.1 devices.
