Add an eSATA port and a USB 3.0 hub port to your Thunderbolt™-equipped MacBook® or laptop

  • 1 x eSATA (5Gbps) and 1 x USB 3.0 port (5Gbps), through a Thunderbolt connection

  • Compact and durable case design with an integrated Thunderbolt cable, for maximum portability

  • Supports Thunderbolt data rates of up to 10Gbps, with 2 dedicated PCI Express lanes (one per port)

The TB2USB3ES Thunderbolt™ to eSATA + USB 3.0 Adapter lets you expand your MacBook or laptop connectivity by combining Thunderbolt to eSATA and Thunderbolt to USB 3.0 functionality into a single, compact adapter. You gain two vital interfaces that are unavailable or limited on most Thunderbolt-equipped systems, delivering fast, reliable performance, more connection possibilities, and rugged portability.

Fast, Reliable Performance

Experience fast, effective and reliable performance from your essential peripherals! Now, you can leverage the 10 Gbps bandwidth of your Thunderbolt port to create a scalable, high-speed solution that offers eSATA and USB 3.0 connectivity.

To maximize efficiency, two dedicated lanes connect the Thunderbolt adapter directly to your system PCIe bus. Each lane delivers 5 Gbps bandwidth so you effectively avoid performance bottlenecks when both ports are in use. This versatile adapter gives you fast, simple and reliable external connectivity, offered by revolutionary Thunderbolt technology.

Thunderbolt Performance With 2 Dedicated PCI Express Lanes

Connection Possibilities

Take full advantage of your current peripherals! Saving you the added expense of purchasing new devices, this single adapter lets you simultaneously connect your existing peripherals through your Thunderbolt port - perfect for eSATA external hard drives (with SATA III support), as well as USB 3.0 hubs (with UASP support), or for syncing with your tablet or smartphone.

You can even integrate the adapter into the end of a Thunderbolt daisy-chain configuration! Connect the adapter to your Thunderbolt Docking Station (SKU: TBDOCKHDPBC - sold separately), for further MacBook expandability!
