USB 3.0 PCIe Expansion Card - 4-Port SuperSpeed Adapter with 2x 5Gbps Channels (PEXUSB3S42V) StarTech.com

The USB 3.0 PCIe expansion card adds four high-speed ports to your computer, allowing you to connect multiple devices simultaneously. It uses two dedicated 5 Gbps channels for data transfer, which helps avoid performance bottlenecks that can occur with traditional single-channel USB 3.0 cards. This design ensures faster file transfers and better overall performance when using multiple USB devices at once.

The card supports UASP (USB Attached SCSI Protocol), which allows for more efficient data transfers by processing multiple commands at the same time. This can significantly increase transfer speeds when used with compatible devices and operating systems. Additionally, the card includes an optional SATA or LP4 power connector to provide more power to high-demand USB devices, ensuring they operate at their full potential.

This expansion card is compatible with PCIe x4-enabled systems and works with both USB 3.0 and older USB 2.0 / 1.1 devices. It supports the USB Battery Charging Specification 1.2, which allows for faster charging of Apple devices like iPhones and iPads when connected directly to the card. The card is designed to be backward compatible, making it a versatile upgrade for a wide range of computers.

Installation is straightforward, requiring only a free PCIe slot and a compatible power supply connection if needed. The card comes with all necessary mounting hardware and instructions for setup. It is ideal for users who need additional USB ports for external storage, peripherals, or high-power devices that require more bandwidth and power than standard USB ports can provide.
