The Sonnet Echo Pro ExpressCard 34 Thunderbolt Adapter expands Thunderbolt connectivity to any computer with a Thunderbolt port, enabling you to use a wide variety of ExpressCard/34 cards to add a range of interfaces and capabilities to your system. Because this adapter supports hot-swapping(1), you can select and change the ExpressCard to use as needed—it supports most Sonnet ExpressCard/34 cards, such as our FireWire interfaces and SDXC card readers, select Gigabit Ethernet adapters, USB 3.0 interfaces, eSATA controllers, and interface cards for our Qio E3 and Qio CF4 pro media readers. Sonnet Echo Pro ExpressCard 34 Thunderbolt Adapter also supports specialty adapters like RME's HDSPe ExpressCard, plus interface cards for the AJA io Express and the Matrox MX02 family. Support for Sony SxS memory cards simply requires the installation of Sony's latest SxS driver(2).
