Add More USB Connections Without Compromise
Everybody's got USB peripherals - keyboards, mice, printers, scanners, joysticks, digital cameras, iPod® mobile digital devices, external drives and there never seems to be enough ports on a computer to plug all of them in at the same time. Problem solved install a Sonnet Allegro™ Express USB in your computer to add five more USB 2.0 ports! Considering a hub? Consider the tradeoffs. Every peripheral you plug in has to share a single port's bandwidth (potentially affecting the devices' performance), and you may have to plug it into a power outlet as well as your computer in order to operate some devices.

Sonnet's Allegro Express USB adds five full-bandwidth, high-speed USB connections to your computer without the need for an external box or AC power adapter - no trade-offs necessary. Each of this card's five powered ports supports bus-powered peripherals (devices that work without a separate power supply, including some external drives and scanners) and hi-speed data transmission. With no drivers to install, this card offers simple plug and play installation in Mac and Windows computers. Allegro Express USB adds USB connectivity, outside and in, without compromise.
