The Sonnet Thunderbolt 2 ExpressCard/34 Adapter is not a typical USB adapter—it functions as a Thunderbolt-to-PCI Express bridge, extending a native PCIe lane outside the computer through an ExpressCard/34 slot.
Because Thunderbolt supports PCIe tunneling, ExpressCard devices are detected by the operating system as native PCIe hardware, allowing them to use their original drivers and deliver near-native performance. This provides lower latency, better compatibility, and support for advanced features such as DMA, SMART, TRIM (when supported), and direct access to PCIe devices.
It is ideal for professional ExpressCard peripherals, including SATA/eSATA controllers, FireWire adapters, USB 3.0 controllers, Gigabit Ethernet cards, RME audio interfaces, and Sony SxS/XQD card readers.
