The StarTech.com PEXUSB3S24 is a PCIe x1 card that adds two USB 3.0 Type-A ports supporting data rates up to 5 Gbps and UASP, making it suitable for desktop users who need more high-speed USB connections.
Recommended For
- Owners of older desktop PCs with an available PCIe x1 slot who want to add two USB-A USB 3.0 ports for newer external drives or peripherals.
- Desktop users who regularly move files between a PC and a UASP-compatible external SSD or hard-drive enclosure, and want a dedicated USB 3.0 connection for those transfers.
- Small-form-factor desktop owners who need two rear USB-A ports and can use the included low-profile bracket.
- Linux users upgrading a PCIe desktop for basic USB 3.0 peripheral or storage connections, provided their distribution and kernel support the card’s Renesas/NEC controller.
- Homelab users exploring PCIe USB-controller passthrough to a virtual machine; community discussion names the PEXUSB3S24 as a candidate, but passthrough success depends on the host and setup.
