PCI Express is the next revolution in I/O interconnect standards that will deliver the bandwidth and features required by PCs, consumer electronics and communications devices. The architecture is a cost-effective, low-pin count, and point-to-point technologies offering maximum bandwidth, reducing cost and design complexity and enabling smaller form factors. USB4414N is the best solution for USB2.0 High-Speed PCI Express and the interface has a potential transfer rates of 2.5 Gbps using a single-lane (or x1) PCI Express link. SUNIX USB4414N equips Hot-Swapping and plug-n-Play feature, and you don't have to not only power down your system installing hardware but also worry about running out of slots on your mainboard or those confusing IRQ's again. The USB2.0 High-Speed implementation of the Universal Serial Bus standard supports transfer speeds up to 480 Mbps. With USB USB2.0 High-Speed ports, its make you connect kinds of USB devices and peripheral to your desktop computer instantly and conveniently, such as hubs, data storage devices, PC video cameras, digital cameras, CD-R/RWs, DVD-ROMs, scanners, printers, memory card readers, and more.
