Sonnet Allegro Pro USB 3.0 PCIe card

Add four powerful 5 gb/s super speed USB 3.0 ports-each with its own dedicated controller. Do you frequently need to hook up multiple USB 3.0 drives for fast backups and drive-to-drive duplication? If you are looking for the best possible performance, install the allegro pro USB 3.0 PCIe adapter in your mac pro tower, windows PC or thunderbolt 2-to-PCIe card expansion system. This pro sonnet card adds four super speed USB 3.0 ports to your computer, but unlike conventional adapter cards, each port has its own controller. Instead of sharing a single controller's bandwidth, each port gets its own, enabling the allegro pro card to support aggregate transfer speeds of up to 1,800 mb/s (450 mb/s per port). The allegro pro USB 3.0 PCIe card features a PCIe 2.0 x4 bus interface to take advantage of one of your computer's fast expansion card slots. This card installs easily into any x4 pci express (PCIe) slot that supports a full-height card, features hot-pluggable and hot-swappable device connection support with automatic device configuration and works with all usb-if compliant USB 3.0 and USB 2.0 peripherals.
