Upgrade to SuperSpeed Performance
Your computer’s USB 2.0 ports are perfectly adequate for connecting mice, keyboards, and printers, but if you need to connect external storage drives, USB 2.0 ports are underpowered in more ways than one—limiting data transfer speeds to around 25–30 MB/s, they can hardly be called “high performance”. Most drives available today include faster USB interfaces and offer significantly better performance than USB 2.0-equipped drives. Though you can connect them to your computer’s USB 2.0 ports, their performance would be reduced by as much as 85 percent! Don’t settle for slow performance—install a Sonnet Allegro Type-A USB 3.2 PCIe 4-Port(1) card to instantly add four SuperSpeed USB 5Gbps ports to your system to take full advantage of today’s drives’ performance capabilities.
PCIe Interface
The Allegro features a PCIe 2.0 bus interface to take advantage of your computer’s fast expansion card slots. This card installs easily into any 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 peripherals.
Powerful Ports
Sonnet specially engineered the Allegro PCIe 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!
Add Four USB 3.0 Ports to Older Mac Computers with USB 2.0
Got an older Mac with USB 2.0 ports, no PCIe slots, and a Thunderbolt or Thunderbolt 2 port? The Allegro is a great way to add four USB-A 5Gbps ports for use in Sonnet’s Thunderbolt 2 and Thunderbolt 3 to PCIe card expansion systems, including Echo Express™ and xMac™ desktop and rackmount systems.
Perfect for the Extra Slot in Your Multi-Slot Thunderbolt System
Have a multi-slot Thunderbolt 2 or Thunderbolt 3 to PCIe card expansion system with an open slot? Installing an Allegro Type-A USB 3.2 PCIe 4-Port card is an excellent way to inexpensively add four SuperSpeed USB-A 5Gbps ports to your computer.
