Sonnet's Presto Gigabit USB 3.0, an USB 3.0-to-Gigabit Ethernet adapter, provides users with an easy way to add Gigabit Ethernet-wired networking connectivity to Mac and Windows computers with USB 3.0 ports. Plus, it's backward-compatible with USB 2.0.

The Presto Gigabit USB 3.0 adapter supports 1000/100/10BaseT auto negotiation and full/half duplex communication, enabling it to connect with most networks. It also supports jumbo packet transfers (compared to 1,500-byte standard packets) to provide higher performance and reduced overhead when transferring large files.

With the introduction of thinner and lighter computers, manufacturers continue to remove ports that were once standard. One of the first to go was the bulky RJ-45 connector for Ethernet, the wired networking interface standard. The connector is no longer present on popular computers such as the MacBook Air and MacBook Pro. Sonnet's Presto Gigabit USB 3.0 adapter bridges the gap left by the missing onboard RJ-45 port, enabling wired file access and sharing at up to 1 Gb/sec.

The port-powered Presto Gigabit USB 3.0 is energy-efficient while in use, and consumes even less power when no data is being transmitted. This adapter includes a short USB 3.0 cable to keep the device close to the computer and allow the user to see its power, link, and activity LED indicators.

The Presto Gigabit USB 3.0 adapter is available at a suggested retail price of $39. More information on this product is available at http://tinyurl.com/l2y2t9g .
