Introduction
The PCIUSB3S22/PCIUSB3S4 2/4-Port PCI to SuperSpeed USB 3.0 Card, with SATA
power, allows for legacy PCI slots to support the USB 3.0 standard, which is capable of
data transfer rates up to 5 Gbps (10x faster than USB 2.0). Using USB 3.0 devices with
this card will increase data transfers, with up to 1.3 Gbps of available bandwidth (PCI
bus limit), more than double the performance versus USB 2.0. With optional power
connectors, each USB port can provide up to 900mA of power to connected USB 3.0
devices, ensuring sucient power for the most power hungry devices. Backward
compatible with USB 2.0 and 1.x devices, this versatile PCI USB 3.0 card will work with
any future USB 3.0 devices, while still being able to support older devices. Designed for
older PCI-based systems or computers with only PCI expansion slots left available, this
adapter card allows those systems to stay relevant and up-to-date with the latest USB
technology. Backed by a StarTech.com lifetime warranty and free lifetime
technical support.
