StarTech.com 4 Port PCI Express (PCIe) SuperSpeed USB 3.0 Card Adapter
W/ 2 Dedicated 5Gbps Channels

Product Description

Add four USB (Universal Serial Bus) 3.0 ports with two independent channels, LP/SATA power, & charging support to your PC through a PCI Express slot. The PEXUSB3S42V 4-Port PCI Express USB (Universal Serial Bus) 3.0 Card lets you add four USB (Universal Serial Bus) 3.0 ports with two dedicated 5 Gbps channels to your PCIe x 4-enabled PC. This independent port architecture improves USB (Universal Serial Bus) 3.0 performance by transferring data on two individual channels to your computer, giving you faster file transfers. When multiple devices are connected, traditional single bus USB (Universal Serial Bus) 3.0 cards share your 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, & effectively doubles your total available to bandwidth to 10 Gbps. Enhanced with UASP support (USB Attached SCSI Protocol), this USB (Universal Serial Bus) 3.0 controller performs up to 70% faster than conventional USB (Universal Serial Bus) 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 (Universal Serial Bus) 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 (Universal Serial Bus) devices, this PCIe USB (Universal Serial Bus) 3.0 card

Includes:: an optional SATA or LP4 power connector to connect to your system power supply & deliver up to 900m A of power per port to USB (Universal Serial Bus) 3.0 bus-powered devices (500m A for USB (Universal Serial Bus) 2.0). The USB (Universal Serial Bus) 3.0 card also supports USB (Universal Serial Bus) Battery Charging

Specification 1.2 (Apple Mode only), letting you charge compatible Apple devices (iPhones & iPads) faster than a standard USB (Universal Serial Bus) 3.0 port. The controller card is compliant with USB (Universal Serial Bus) 3.0 standards while offering backward compatibility with existing USB (Universal Serial Bus) 2.0 / 1.1 devices. For added versatility, the USB (Universal Serial Bus) 3.0 PCIe card is equipped with a standard profile bracket &

Includes:: a low-profile
