A PCI Express USB 3.0 2-port expansion card is a hardware device that adds additional USB 3.0 ports to your computer system by connecting to a PCIe slot on your motherboard. Here are the typical details you might find for such a card:

1. Interface: PCI Express (PCIe) interface, which provides high-speed data transfer between the expansion card and the motherboard.

2. USB Ports: Two USB 3.0 ports for connecting various USB devices, such as external hard drives, flash drives, printers, cameras, and more. USB 3.0 ports offer faster data transfer speeds compared to USB 2.0, making them suitable for high-bandwidth devices.

3. Data Transfer Speed: USB 3.0 ports support data transfer speeds of up to 5 Gbps (gigabits per second), allowing for quick file transfers and efficient data access.

4. Compatibility: Compatible with standard PCI Express slots on desktop computers. Ensure that your motherboard has an available PCIe slot and is compatible with the expansion card.

5. Backward Compatib
