The PEXUSB3S44V 4-Port PCI Express USB 30 Card lets you add four quad bus USB 30 ports to your PCIe x4-enabled PC Quad bus architecture improves USB 30 performance by transferring data on independent channels to your computer giving you faster file transfers When multiple devices are connected traditional single bus USB 30 cards share your maximum bandwidth between all ports By employing four host controller chipsets each port operates on a separate independent transmission channel Allocating 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 30 controller performs up to 70 faster than conventional USB 30 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 See our UASP test results below for further details For high-power USB devices this PCIe USB 30 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 30 bus-powered devices (500mA for USB 20) The USB 30 card also supports USB Battery Charging Specification 12 (Apple Mode only) letting you charge compatible Apple devices (iPhones and iPads) faster than a standard USB 30 port The controller card is compliant with USB 30 standards while offering backward compatibility with existing USB 20 11 devices For added versatility the USB 30 PCIe card is equipped with a standard profile bracket and includes a low-profilehalf-height bracket for installation in small form-factor computers Provides four external quad bus USB 30 PortsSupports up to 20 Gbps total transfer bandwidth – Up to 5 Gbps per portUASP support across all four portsPCIe x4 interface compliant with PCI Express 20 specificationsOptional LP4 or SATA power connector provides up to 900mA per USB portSupports USB Battery Charging Specification 12 (Apple Mode only)Fully compliant with USB 30 rev 10 and Intel xHCI rev 10 specificationsBackward compatible with USB 20 and USB 1011 devicesIncludes a Low Profilehalf-height installation bracketHot-swap feature to connectdisconnect devices without powering down the systemPerformanceData Transfer Rate Up to 50 GbpsInterfacesPortsExternal Connectors 4 – USB 30 A (9 pin; SuperSpeed) FemaleInternal Connectors 1 – LP4 (4 pin; Molex Large Drive Power) Female • 1 – SATA Power (15 pin) PlugConnector 1 – PCI Express x4 MaleSystem RequirementsOperating Systems Supported Windows 8 (3264) 7 (3264) Vista (3264) XP (3264) • Windows Server 2012 2008 R2 2003 (3264) • Linux Kernel 2631 or laterEnvironmentalEnvironmental Operating Temperature 0 to 50 °C – Humidity 5 to 85 PhysicalForm Factor PCI Express CardIn The Box 1 – 4 Port PCIe USB Card • 1 – Low Profile Bracket • 1 – Driver CD • 1 – Instruction ManualDimensions 15 cm (W) x 167 cm (D) x 55 cm (H) – 090 kg
