Product description

Size Name:4 Ext Dual Bus  |  Style Name:PCI Express

Product Description

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

Faster USB performance
When multiple devices are connected, traditional single bus USB 3.0 cards share the maximum bandwidth between all ports. By employing a second host controller chipset, the transmission channel is shared across two ports rather than four. Dedicating up to 5 Gbps for each set of two ports reduces performance bottlenecks and doubles your total available bandwidth to 10 Gbps.

Enhanced with UASP support (USB Attached SCSI Protocol), the card performs up to 70 percent 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 Bulk-Only Transport, UASP technology optimizes transfers by allowing multiple commands to be processed simultaneously, significantly increasing transfer speeds on data transfers.

For high-power USB devices, this 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 card also supports USB Battery Charging Specification 1.2 (Apple Mode only), letting you charge compatible Apple devices (iPhones and iPads) faster than a standard USB 3.0 port.

Compatible with older USB devices
The controller card is compliant with USB 3.0 standards and is backward compatible with existing USB 2.0 / 1.1 devices. The USB 3.0 PCIe card ships with a separate low-profile bracket in the box, for installation in small form-factor computers.

PEXUSB3S42V is backed by a StarTech 2-year warranty and free lifetime technical support.
