Sonnet Allegro Pro Type-A USB 3.2 PCIe
Powerful USB 3.2 Gen 2 Performance
Add Four USB-A 10Gbps Ports to Mac Pro and Windows Computers with PCIe Slots; and Thunderbolt to PCIe Card Expansion Systems
The fastest SSD-based USB 3.2 Gen 2 drives now available can transfer data at 800 MB/s—many are bus-powered, too. But, most desktop computers (including many new models) feature old-generation USB interfaces that can’t support that performance, and may not provide enough power to enable those bus-powered drives to function. Break through the bottleneck—install Sonnet’s Allegro Pro Type-A USB 3.2 PCIe(1) card in your Mac Pro® or Windows® PC computer with PCIe slots; or Thunderbolt™ to PCIe card expansion system to support your fast USB drives at maximum performance.
Two Gen 2 Controllers, Four USB-A Ports
Featuring two 10Gbps USB 3.2 Gen 2 controllers and four USB-A ports, the Allegro PCIe card supports the fastest USB drives available, yet provides the most common connection type for peripheral devices.
The Speed and Power
Connected to a single USB 3.2 Gen 2 SSD RAID device, Sonnet’s Allegro PCIe card supports data transfers up to 800 MB/s—transfers complete in half the time(2) compared with using a USB 3.1 Gen 1 or USB 3.0 adapter card! Made possible through the use of dual controllers, with two connected drives, each port supports simultaneous 660 MB/s transfers. With four drives connected, each port supports simultaneous 300 MB/s transfers!
Sonnet Port Power Advantages:
Unlike ordinary USB adapter cards, Sonnet's Allegro PCIe card was designed with a focus on intelligent power management and delivery for powering attached drives through its ports.
No Auxiliary Power Needed
Ordinary USB-A cards require the connection of a separate power connector. The Allegro draws the power it needs from the slot it’s installed in to power connected drives, enabling you to install the card in any compatible computer or Thunderbolt expansion system that doesn’t have these power connectors available.
Independent Power Regulation for Each Port
Ordinary USB-A cards can provide poor power regulation through their ports. The Allegro PCIe card protects each port from power glitches on adjacent ports—such as when a hard drive spins up after connection—preventing auto-disconnects of already-connected drives.
Resettable Fuses
Unlike ordinary USB-A cards, the Allegro features a resettable fuse on each port to protect the card and your computer should a cable or peripheral fail. Resetting a tripped fuse is simple— just shut down and restart your computer.
Add USB 3.2 to Your Thunderbolt Mac
Got a Mac with a Thunderbolt connection, but no PCIe slot? The Allegro is ideal 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 Pro Type-A USB 3.2 PCIe card is an excellent way to inexpensively add four SuperSpeed USB-A 10Gbs ports to your computer.
