SoNNeT Allegro USB PCIe Card 4-Extended + 1-Int USB2 Ports Macintosh/Windows Model USB2-E

Add More USB Connections Without Compromise
Everybody's got USB 2.0 peripherals - keyboards, mice, printers, scanners, joysticks, digital cameras, external drives, an iPod®, an iPhone® - 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™ USB PCIe in your computer to add five more USB 2.0 ports! Considering a hub? Consider the trade-offs. 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 USB PCIe adds five (four external, one internal) high-speed USB 2.0 connections to your computer without the need for an external box or AC power adapter - no trade-offs necessary. This Sonnet adapter features hot-pluggable and hot-swappable device connection support with automatic device configuration, so you can plug in and disconnect devices without having to shut down your computer. Each of Allegro USB PCIe’s five powered ports supports bus-powered peripherals (devices that work without a separate power supply, including some small 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 USB PCIe adds more USB 2.0 connectivity to your computer, outside and in, without compromise.
