The StarTech.com PEXUSB312A3 is a PCIe expansion card that adds two USB-A ports rated up to 10Gbps each, suited to desktop or server users who need more high-speed USB connectivity for external SSDs and other peripherals.
Recommended For
- Desktop users who regularly move large files between a USB-A external SSD or NVMe enclosure and their PC, and need a 10Gbps USB port where the motherboard lacks one.
- PC builders or workstation users adding two USB-A ports for high-speed external drives and other USB devices, with an available PCIe x4-or-larger slot.
- Users connecting a mix of USB storage and older USB 3.0 or USB 2.0 peripherals who want them on an add-in controller; the card supports those earlier USB standards and UASP storage devices.
- Small-form-factor desktop builders who need added USB-A ports and can use the included low-profile bracket in a compatible PCIe slot.
