Product Description
The StarTech.com PEXUSB3S11 2 Port PCIe USB 3.0 Card is designed to expand connectivity within computers by offering both internal and external USB 3.0 ports. Engineered for high performance, this card utilizes PCI Express 2.0 for rapid data transfers, supporting speeds up to 5Gbps on Super Speed USB 3.0 connections. Backward compatibility ensures seamless integration with older USB 2.0 and USB 1.1 devices, allowing a versatile range of peripherals to connect.
Enhanced with UASP (USB Attached SCSI Protocol) support, the PCIe card offers up to 70% faster read and 40% faster write speeds compared to traditional USB 3.0, when paired with UASP-enabled enclosures and compatible operating systems. UASP optimizes protocol efficiency, enabling simultaneous command processing, which significantly reduces transfer times and processor load. This feature is particularly advantageous for environments with frequent large file transfers or high-performance storage needs.
Offering both internal and external ports, the PEXUSB3S11 is ideal for connecting front-bay hubs, internal storage solutions, or external peripherals such as printers, scanners, and external hard drives. The optional SATA power connector delivers up to 900mA per port for USB 3.0 bus-powered devices, ensuring adequate power supply for high-demand peripherals, while USB 2.0 ports receive 500mA.
Fully compliant with USB 3.0 revision 1.0 and Intel xHCI rev0.96 specifications, the card supports diverse communication types including Control, Bulk, Interrupt, and Isochronous transfers. Hot Swapping and Plug-and-Play compliance means users can connect or disconnect devices without system restart, streamlining workflow and minimizing downtime.
Safety and environmental compliance are assured through adherence to CE and RoHS standards. The robust design and technical features make this card suitable for diverse applications, including industrial automation, laboratory data acquisition, manufacturing environments, commercial workstations, and IT infrastructure upgrades. Backed by a lifetime warranty and technical support, the StarTech.com PEXUSB3S11 delivers reliable USB expansion for demanding applications.
