Sonnet has introduced the compact Presto Gigabit USB 3.0, a USB 3.0-to-Gigabit Ethernet adapter. The Presto adapter provides users with a simple way to add Gigabit Ethernet-wired networking connectivity to Mac and Windows computers with USB 3.0 ports, exploiting the 5Gb/sec SuperSpeed USB 3.0 interface to deliver full Gigabit speed performance with suitably equipped computers. This Sonnet adapter is also backward-compatible with USB 2.0.
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, MacBook Pro, and many Ultrabook devices. Sonnet's Presto Gigabit USB 3.0 adapter instantly bridges the gap left by the missing onboard RJ-45 port, enabling wired file access and sharing at up to 1Gb/sec.
The Presto Gigabit USB 3.0 adapter supports 1000/100/10BaseT auto negotiation and full/half duplex communication, enabling it to connect easily 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.
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 (part number USB3-GE) is now available at a suggested retail price of US$39.
