The StarTech.com 2-Port 10Gbps USB-A & USB-C PCIe Card (PEXUSB311AC3) is an internal PCI Express expansion card that adds high-speed connectivity to desktop computers or servers. It uses a PCIe 3.0 interface to provide a maximum data transfer rate of 10 Gbit/s per port, doubling the throughput of standard USB 3.0 connections. These speeds support tasks such as transferring large files to NVMe-based external storage. The ASMedia ASM3142 chipset manages data across both ports simultaneously.
The card features one USB 3.2 Gen 2 Type-C port and one USB 3.2 Gen 2 Type-A port. It includes brackets for both full-height and low-profile installations to accommodate standard and small-form-factor cases. Integrated UASP technology improves read and write performance when using external drives. The hardware is compatible with Windows, macOS, and Linux systems. The printed circuit board is red.
