Product Description & Reviews
The 4-Port USB 3.0 PCI Express card lets you add four dedicated 5Gbps 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 using four host controller chipsets, each port operates on a separate independent transmission channel. Dedicating up to 5Gbps to each USB port reduces performance bottlenecks, and effectively quadruples your total available bandwidth to 20Gbps. Enhanced with UASP support (USB Attached SCSI Protocol), this USB PCIe card performs up to 70% faster than conventional USB 3.0, when paired with a UASP supported enclosure. (Note: UASP requires a compatible operating system). 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 an optional SATA or LP4 power connector to connect to your system power supply and deliver up to 900mA of power per port to USB 3.0 bus-powered devices (500mA for USB 2.0). The USB 3.0 card also supports USB Battery Charging Specification 1.2 (Apple Mode only), letting you charge compatible Apple devices (iPhones and iPads) faster than using a standard USB 3.0 port. The USB 3.0 expansion card is backward compatible with existing USB 2.0 / 1.1 devices. For added versatility, the card is equipped with a standard-profile bracket and includes a low-profile (half-height) bracket for installation in small form-factor computers. The PEXUSB3S44V is backed by a StarTech.com 2-year warranty and free lifetime technical support.
