Sonnet Echo Thunderbolt to ExpressCard/34 Adapter

Sonnet Echo Thunderbolt to ExpressCard Adapter Harnessing both the incredible speed and powerful flexibility that the Thunderbolt interface offers, Sonnet presents a product that opens the range of ExpressCard devices to computer systems with no or little expandability. The Echo Thunderbolt to ExpressCard/34 Adapter allows Thunderbolt equipped iMacs, MacBook Airs, MacBook Pro, and Mac minis, to now take advantage of high end devices like eSATA 6Gb/s, add additional FireWire 800 ports, and even utilize PCIe based SDXC UHS-I or UDMA6 CompactFlash Readers at full throughput! Even more exciting is that fact that these systems can now use speciality products one only available for use with high end machines featuring built in expansion slots. Examples include Sonnet's Qio Universal Media Reader, the AJA io Express, or the Matrox MX02 family of products. A Mac Pro or 17-inch MacBook Pro is no longer manatory for interfacing with special hardware,

Set up for this Sonnet adapter is simple—just connect it directly to your computer or at the end of a Thunderbolt device chain with a Thunderbolt cable (not included, sold at the Apple Store)—that's it. There's no software to install and no power supply to plug in. Plug the ExpressCard/34 card into the Echo ExpressCard/34 Thunderbolt Adapter as you would into a notebook computer's ExpressCard slot, install software for the adapter if necessary, and you are ready to work. Sonnet's Echo ExpressCard/34 Thunderbolt Adapter gives you the additional connectivity you need, today. Please see Sonnet's Compatibility List before purchasing this device.
