New card brings USB 3.0 support to original Mac Pro line
Upgrade vendor Sonnet 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.
The 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. Four USB 3.0 ports are available to users, with two external USB 3.0 ports and a 20-pin header for two internal USB 3.0 ports.
The Tango 3.0 PCIe adapter card (part number FW8USB3-E) is now available at a suggested retail price of $99. The card is compatible with OS X 10.8.4 and above, OS X 10.9 Mavericks, and Windows 7 and 8.
