Four-Port USB 3.0 Expansion Card
This PCIe add-in card adds two external and two internal USB 3.0 ports to a desktop system. The internal ports use a standard 20-pin header for front-panel or drive-bay brackets. It delivers SuperSpeed data rates up to 5.0 Gbps and remains compatible with USB 2.0 and 1.1 devices.
Builders Adding Front-Panel Ports
The card suits enthusiasts upgrading an older chassis that lacks native USB 3.0 headers or users who need extra high-speed ports for external drives and peripherals. It is not for systems without a free PCIe slot or for anyone requiring USB 3.1 or 3.2 transfer speeds beyond the 5.0 Gbps limit.
Single-Lane PCIe Interface
The controller connects through a single PCIe lane, so total bandwidth is shared across all four ports when multiple devices transfer simultaneously. This shared throughput is the key specification that determines whether the card meets a specific multi-device workload.

أسئلة حول هذا المنتج
Should I pick the version with two external and two internal ports or a different layout?
This model provides exactly two external USB 3.0 ports and two internal USB 3.0 ports using a 20-pin header, so there is no alternative layout to choose.
What does the 5.0 Gbps rate actually deliver when I plug in a drive?
The 5.0 Gbps figure is the theoretical maximum of the USB 3.0 interface; real-world throughput will be lower due to protocol overhead and the performance of the connected storage device.
Which PCIe interface does the card use and what bandwidth does that provide?
The card installs in a standard PCI Express slot; the USB 3.0 controller is limited to 5.0 Gbps per port regardless of the PCIe generation.
