The StarTech.com 4-Port USB 3.0 PCI Express Expansion Card adds four external USB 3.0 ports to a computer system, supporting data transfer speeds up to 5 Gbps. It is compatible with USB 2.0 and 1.x devices, making it a versatile upgrade for systems needing more connectivity options. The card is ideal for users who require faster data transfers, such as those working with large files or external storage devices.
This expansion card includes UASP (USB Attached SCSI Protocol) support, which allows for faster data transfers by enabling multiple commands to be processed simultaneously. This feature can improve performance by up to 70% when used with compatible enclosures and operating systems. However, UASP functionality requires a compatible OS, so users should verify their system meets this requirement before installation.
The card uses a stacked port layout, placing the four USB ports one on top of the other. This design allows all ports to be external-facing while fitting into low-profile or small form factor systems. A low-profile bracket is included to ensure compatibility with compact cases. The built-in SATA power connector allows each port to supply up to 900mA of power, which is useful for powering external devices that require more than standard USB power.
Installation requires a free PCI Express slot on the motherboard. The card is suitable for desktop computers that support PCIe expansion. It does not include additional software or drivers beyond what is necessary for basic operation. Users should ensure their system has a SATA power connector available for optimal use of the power delivery feature.
