Sonnet today introduced the Tango 3.0 PCIe, a combination USB 3.0 and FireWire 800 PCIe adapter card. The Tango card provides users with a simple way to add USB 3.0 and FireWire 800 connectivity to Mac Pro and Windows computers with PCIe slots, and to Thunderbolt-to-PCI Express expansion chassis. This Sonnet adapter can run bus-powered devices such as hard drives through each of its ports, and it is also backward-compatible with USB 2.0 and FireWire 400 devices.

USB 3.0, which offers a tenfold increase in data transfer speeds over USB 2.0, has become a standard interface on Mac systems and most Windows PCs, as well as external storage devices. The iconic, but now discontinued, Mac Pro tower never included native USB 3.0 ports, and many perfectly functional PCs were built with only USB 2.0 ports. Therefore, users wanting to take advantage of the new fast interface have to rely on third-party expansion cards. The Sonnet adapter provides four USB 3.0 ports: two external USB 3.0 ports and a 20-pin header for two internal USB 3.0 ports. The internal ports support panel-mount connector kits (sold separately).
