Echo Pro
ExpressCard/34 Thunderbolt Adapter

Mac / PC / Thunderbolt / ExpressCard
Add ExpressCard/34 and SxS card reader support via Thunderbolt
Expanding Beyond the Box
Thunderbolt technology is amazing-the speed (up to 10Gb/s) and versatility (supporting high-resolution displays plus high-performance data devices through a single, compact port) make it clear that this is the next generation I/O technology, available today. But what about connecting existing FireWire® and eSATA peripherals, as well as high speed memory cards? Sonnet's Echo ExpressCard/34 Thunderbolt Adapters expand Thunderbolt connectivity to support more than just storage systems and monitors. This Sonnet adapter adds an ExpressCard/34 slot to any computer to which it's connected, enabling you to use a wide variety of ExpressCard/34 cards to add a range of interfaces and capabilities to your system. Plus, it's the fastest, least expensive SxS™ memory card reader available!
Add more connectivity options to your system
Imagine adding more FireWire ports or an eSATA interface through a single Thunderbolt adapter. These card adapters allow you to choose your connections and add more to your setup. Because these adapters support hot-swapping, you can select and change the ExpressCard to use as needed-they supports most Sonnet ExpressCard/34 cards (with a PCI Express interface), such as our FireWire interfaces, CompactFlash® and SDXC™ card readers, select eSATA controllers, and interface cards for our Qio™ CF4 and Qio E3 pro media readers. They also support 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*.
Simple setup
Set up for these Sonnet adapters is simple-just connect one 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 or SxS memory 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.
Versatile Connectivity via Thunderbolt
Sonnet's Echo ExpressCard/34 Thunderbolt Adapter opens a world of connectivity options to any Thunderbolt technology-enabled computer. ExpressCard/34 adapters, originally intended for use with notebook computers, offer users additional connectivity and functionality beyond what's available through their computers' stock configuration. With Sonnet's EchoExpressCard/34 Thunderbolt Adapter, you can have an eSATA Thunderbolt adapter, a FireWire 800 Thunderbolt adapter, or an SDXC or CF Thunderbolt adapter.
Supports Ultimate Performance with PCIe 2.0 Interface for ExpressCard 2.0 Cards
The Pro version supports ExpressCard 2.0 cards at full bandwidth for the ultimate performance (for example, Sonnet's newest super-fast Pro eSATA cards yield read/write speeds as high as 375 MB/s.) Ingest footage from SxS memory cards at up to 100 MB/s. The Echo Express Pro also includes a 5-year warranty. Sonnet's Echo ExpressCard/34 Thunderbolt Adapter gives you the additional connectivity you need, today.

  1. Requires Thunderbolt cable (sold separately).
  2. Under Windows, ExpressCard must be plugged in before plugging in Thunderbolt cable.
  3. Drivers: SxS Device Drivers Installer for OS X, Sony SxS UDF Driver 2.1.1, XQD Adapter Device Drivers Installer for OS X, Echo ExpressCard Thunderbolt Adapters Thunderbolt Hot Plug Drivers (Windows) 1.0
  4. A computer's ExpressCard slot supports two bus standards, PCIe and USB. ExpressCard adapters fall into two basic categories: those that use the ExpressCard's PCIe interface, and those that use its USB interface. Upon inserting the ExpressCard card, a computer automatically senses which interface the adapter is using. Examples of PCIe-based adapters include the cards listed above. Examples of USB-based adapters include USB 2.0 adapter cards and many multi-format memory card readers such as Sonnet's 21-in-1 Multimedia Memory Card Reader & Writer. 

    Thunderbolt technology natively supports the PCIe bus standard, but not USB, so the Echo adapter only interfaces with PCIe-based ExpressCard/34 adapters. As a result, all USB-based ExpressCard/34 cards are unsupported.
