Product Description


USB 3.0 for Fast Performance and Common Connectivity

Most drives available today include USB 3.0 interfaces. Although you can connect them to the USB 2.0 ports on your computer, their performance would be reduced by as much as 85 percent! This useful adapter offers native USB 3.0 support to ensure great performance from the fast drives you connect, enabling data transfers at up to 350 MB/s. Need to connect more than one drive? It works with multi-drive enclosures with hardware raid controllers, too. This adapter also supports hubs and other USB 3.0 devices, and is backward compatible with USB 2.0 devices. If your computer already has USB 3.0 onboard, this adapter provides another handy port.

eSATA for Extra Speed

Sonnet’s USB 3.0+eSATA Thunderbolt Adapter is well suited to handle the increased bandwidth requirements of 6Gb/s SSDs through its fast eSATA interface. Capable of transferring files at up to 375 MB/s, this Thunderbolt adapter also supports the latest multi-drive enclosures with hardware raid controllers, and older ones with port multipliers, enabling you to access up to five drives through one eSATA cable. The eSATA port allows you to boot from an attached drive under OS X, and offers support for media readers with eSATA interfaces such as the RED STATION REDMAG 1.8" and 2.5".

Simple to Set Up, Simple to Use

When used with a Mac computer, the USB 3.0+eSATA Thunderbolt Adapter requires no setup—the necessary drivers are already installed—just plug it into your computer and it works. When connected to a Windows PC, a simple driver download and installation is all that’s required to get you going.

This device is bus-powered, so there’s no need to connect an AC power adapter, making it perfect for use anywhere. Wherever you use it, the Sonnet USB 3.0+eSATA Thunderbolt Adapter is a simple and cost-effective solution that enables you to simultaneously connect your USB 3.0 and eSATA peripherals without hassle.
