Sonnet Technologies has announced the Echo ExpressCard/34 Thunderbolt Adapter, which enables the use of many Sonnet ExpressCard/34 adapters with computers equipped with a Thunderbolt port, including the latest iMac, Mac mini, MacBook Air, and MacBook Pro models. ExpressCard/34 adapters, originally intended for notebook computers, offer users additional connectivity and functionality beyond what’s available through their computers’ stock configuration. 

The new Echo ExpressCard/34 Thunderbolt Adapter supports most PCI Express-based Sonnet professional ExpressCard/34 adapters and specialty adapters from other manufacturers. Sonnet expects other manufacturers’ ExpressCard/34 products to become compatible as their drivers are updated to be Thunderbolt technology-aware.

“The Echo ExpressCard/34 Thunderbolt Adapter gives users tremendous flexibility to connect a wide range of peripheral devices through the Thunderbolt port on their computers,” says Robert Farnsworth, CEO of Sonnet Technologies. “With a single Thunderbolt adapter, they can instantly add connectivity to their computers, whether increasing the number of ports, incorporating new interfaces, or simply using devices that otherwise could not connect through a Thunderbolt port. Support for hot-plugging and -swapping of ExpressCard/34 cards gives customers the freedom to change interfaces and devices when needed.” 

The Echo ExpressCard/34 Thunderbolt Adapter supports Sonnet ExpressCard adapters ranging from CompactFlash and SDXC UHS-I card readers to FireWire 800, Gigabit Ethernet, USB 3.0, and select eSATA adapters. It also supports ExpressCard adapters supplied with specialty devices such as Sonnet’s new line of Qio professional media readers, as well as the AJA Io Express.

The Echo ExpressCard/34 Thunderbolt Adapter is compatible with all Apple computers running Mac OS X and equipped with Thunderbolt ports. It’s expected to be available at the end of October at a suggested retail price of US$149.95. More information about the Echo ExpressCard/34 Thunderbolt Adapter is available at .
