The fastest SSD-based USB 3.1 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 USB 3.1 PCIe card in your Mac Pro® tower, Windows® PC, or Linux computer with PCIe slots; or Thunderbolt™ to PCIe card expansion system to support your fast USB drives at maximum performance.
Featuring two 10Gbps USB 3.1 Gen 2 controllers and four USB-A ports, the Allegro Pro USB 3.1 PCIe card supports the fastest USB drives available, yet provides the most common connection type for peripheral devices.
Connected to a single USB 3.1 Gen 2 SSD RAID device, Sonnet’s Allegro Pro USB 3.1 PCIe card supports data transfers up to 800 MB/s—transfers complete in half the time 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!
Ordinary USB-A cards require the connection of a separate power connector. The Allegro Pro 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 chassis that doesn’t have these power connectors available.
Ordinary USB-A cards can provide poor power regulation through their ports. The Allegro Pro 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.
Unlike ordinary USB-A cards, the Allegro Pro 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.
Got a Thunderbolt connection, but no PCIe slot? The Allegro Pro USB 3.1 PCIe card 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 chassis. Now you can add four SuperSpeed+ USB-A ports to your computer without expansion card slots.
Have a multi-slot Thunderbolt 2 or Thunderbolt 3 to PCIe card expansion chassis with an open slot? Installing an Allegro Pro USB 3.1 PCIe card is an excellent way to inexpensively add four 10Gb USB-A ports to your computer.
The full-height Allegro Pro USB 3.1 PCIe card installs easily into any PCIe x4 (mechanical) or larger slot. The Sonnet card features hot-pluggable and hot-swappable device connection support with automatic device configuration, and works with all USB-IF compliant USB peripherals.
