Product Overview Add Four Powerful 5Gb/s SuperSpeed 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.

4 Independent Controllers!
This pro Sonnet card adds four SuperSpeed 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.(see FAQs)

The Power to Charge and Sync
Sonnet specially engineered the Allegro Pro card to provide extra power through its ports without the need for you to connect an auxiliary power cable. Delivering up to 10W of power per port, this Sonnet solution supports USB 3.0 bus-powered hard drives, SSDs, DVDs & Blu-ray™ devices without the need to connect an additional AC power adapter. The Allegro also supports the USB 3.0 charging specification that enables you to simultaneously charge and sync your iPad®, iPhone®, or other device that supports USB 3.0 charging.

Optimized for Thunderbolt
Got a Thunderbolt connection, but no PCIe slot? This card is ideal for use in one of Sonnet’s Echo Express™ or xMac™ Thunderbolt 2-to-PCIe Card Expansion Systems—the combo enables you to add four SuperSpeed USB 3.0 ports to iMac®, Mac® mini, new Mac Pro®, MacBook Air®, and MacBook Pro® computers with Thunderbolt ports.

Why limit performance by connecting multiple storage devices to your Mac’s built-in USB 3.0 ports? Install the Allegro Pro card into an Echo Express III-D (or other Thunderbolt-to-PCIe card expansion system) and connect it to your Mac via Thunderbolt cable—you’ll add four USB 3.0 ports, each with a dedicated controller, for faster data transfers from media card readers, storage, and other peripherals.

Sonnet Allegro Pro PCIe Ultra High-Performance USB 3.0 Adapter Card With 4 Powered Ports on 4 Independent Controllers is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Excellent product I'm very happy with this card. I've plugged into my Mac Pro 5.1 (2009) running El Capitan and it just worked!! With NO ISSUES whatsoever!!! I've tried the USB 3.1 version before, but it did not work at all with El Capitan. And I'm not moving from this OSX, so I bought this one instead. It is fast enough for me. I use it to connect a couple of external SSDs with pro audio library. It loads everything quite fast.
